What is a TV stabilizer and what it does
A TV stabilizer is an electrical device for converting voltage. Has an input and output, which are designed to adjust the output voltage in a given range.
The stabilizer is an intermediary between electrical appliances and the general power grid of the house. It protects home appliances from damage due to unstable voltage surges.
An unstable voltage value is supplied to the input to the stabilizer. It can fluctuate or act in irregularities. Inside the stabilizer, its value is transformed and then changed within the required range. This ensures the safe operation of the electrical network, and also protects the devices from damage due to voltage surges. At the output, the voltage is always equal to the specified parameters and is supplied to the electrical appliance continuously at the required voltage.
Do i need a voltage regulator for an LCD TV
When buying technical equipment or household appliances, including TVs, sellers advise using them in conjunction with voltage stabilizers. The essence of their joint work is to extend the life and service conditions of the TV.
Many consumers do not use voltage stabilizers for years and their equipment works without interruptions. But once the voltage inside the network goes beyond the permissible limit, the equipment burns out.
In such cases, the question arises. does the LCD TV need a stabilizer??
Is it worth buying
Many new TV models already have built-in stabilizers, the so-called “auto voltages”. They protect the electrical network from interference that the device itself creates. But does not protect against general voltage surges in the network.
All modern household appliances, especially new generation TVs, are equipped with switching power supplies. They continue to operate over a wide input voltage range. Their instructions for use indicate the voltage amplitude at which there will be no damage to the device. It usually ranges from 110 to 250 units.
REFERENCE! If voltage is abruptly applied to the outlet or its value is unstable, you should expect two scenarios.
First, the input voltage is too low. If the voltage is too weak, the TV will simply turn off. An emergency termination of work will not entail any consequences. As soon as the voltage returns to the operating range, you can use the device again.
The second option is a voltage jump above the permissible value. This is the worst case scenario. In such cases, a special element built into the input of the TV is damaged. a varistor.
A varistor is a semiconductor resistor. Its performance and stability depends entirely on the input voltage. A sharp jump in voltage above the desired level will lead to a short circuit.
At the moment of damage to the varistor, the fuse blows and the TV circuit is deactivated. A damaged fuse can be replaced, and the circuit itself will autonomously return to working condition after a while. But excessive overload inside the device will deteriorate its operability and performance each time.
Pros and cons of such a purchase
The advantages of the stabilizer can be considered point by point:
- The entire power grid will be controlled by a stabilizer and balanced in the desired range. about 220 volts. All jumps and fluctuations will be smoothed out, and at the output they will be converted to a stable voltage.
- Safety and durability of equipment performance. Many devices are sensitive to sudden changes in voltage. This leads to breakdowns and malfunctions. The stabilizer will prevent such emergencies.
- Acceptable price. Due to the affordable cost, many consumers can afford to purchase a TV stabilizer without sacrificing their wallet.
- Among the shortcomings, one can single out the exactingness of stabilizers to the operating conditions. They can only be installed in dry locations that are protected from dust and moisture. Any such interference will quickly render the instrument malfunctioning.
The size of the stabilizer and its need for constant cooling can also add to the problem. The stronger the load on the device, the larger its dimensions and the more it will heat up. Proper cooling will protect it from malfunctions.
Despite the prudence of manufacturers and their attempts to secure the operation of devices, power surges can damage the equipment. It remains for the consumer to decide whether it is necessary to minimize the risks of equipment failure.
REFERENCE! There is a good alternative to a voltage regulator. This is a UPS. an uninterruptible power supply. It protects the mains from interference and provides various technological devices with reliable, continuous, uniform power.
In the use of technology, you can do without a stabilizer, but any voltage surge beyond the working upper limit will lead to breakdown of all or individual parts of the device.
Features of modern TVs
All modern electronic devices, including LCD TVs, are equipped with their own switching power supplies covering a wide range of input voltage. At the output of these devices, the voltage is stabilized to the desired level and in this form is supplied to all nodes and elements of the TV.
Thus, TVs, including those of Samsung and Sony, made after 2000, may well do without a separate stabilizer. Sellers literally impose expensive stabilizers on gullible buyers, assuring that without them the TV will not be able to work normally and will immediately burn out in an emergency.
A weighty argument for unscrupulous sellers is often the so-called burnout of pixels due to voltage drops and short circuits. But modern TVs are initially protected from such external influences. In such cases, the direction of the current simply changes, and the receiver itself must turn off after power-off. If the short circuit occurred inside the Led TV, then the stabilizer will not help anything here.
Regarding fading pixels, it is worth noting that they cannot fail by themselves. The cause of the violation, as a rule, turns out to be transistors, which control the entire pixel system. That is, pixels still fly out, and the number of such departures directly depends on the degree of reliability of the entire system.
Do you need a voltage regulator for an LCD TV
All modern electronics are very sensitive to voltage drops in the network, especially at moments of overloads and short circuits. Therefore, where such phenomena occur systematically, it is recommended to connect household appliances together with stabilizing devices. Do you need a voltage regulator for your LCD TV? There is no single answer, everyone makes their own decisions. In any case, the use of a stabilizer will only be beneficial and will protect an expensive TV in a dangerous situation.
Stabilizers with TVs: an excursion into history
During the Soviet era, the population used exclusively tube TVs, which could only work normally together with a voltage stabilizer. These small TVs in a plastic or metal case had a significant weight, heated up during operation, emitting an even, well-audible hum.
Old TVs could theoretically do without a stabilizer, however, even minor fluctuations in the voltage in the network led to noticeable changes in the image, distorted pictures and other unpleasant consequences. Since such situations were repeated regularly, TV stabilizers were used everywhere, thus allowing you to get the required 220 volts. The principle of operation of such stabilizing devices was based on oversaturation of the transformer core, so each of them could operate only in one narrow power range. For example, black and white TVs worked with stabilizers designed for 100-200 watts, and color receivers already needed more powerful devices.
That is, a weak load could not connect to a powerful stabilizer. This led to a violation of the principle of operation and the device simply stopped working. If a powerful load was connected to a weak stabilizer, it quickly began to overheat, and its body melted.
How do LCD TVs behave with voltage surges and going beyond the regulatory limits?
If the readings are too low, the device will simply be turned off without any consequences. After the voltage returns to normal, the TV turns on and works normally.
The situation becomes more complicated when the voltage is too high. In this case, the varistor installed at the input breaks down and fails. As a result, a local short circuit occurs, accompanied by a blown fuse, blackout and shutdown.
After a certain period of time, the varistor returns to its normal state, and the blown fuse is replaced. If such situations arise regularly, you can still use a stabilizer so as not to waste time restoring burnt elements.
When choosing a system, you must adhere to the following rules:
- before buying, consult with our consultants:
- select the optimal power for your equipment;
- the device must be equipped with fuses for protection against short circuits;
- ergonomic design of the device;
- silent work;
- weight and dimensions;
- number of possible connections to the device.
Voltage stabilizer for LCD TVs
Should you buy a voltage regulator for your LCD TV? There is no single answer to this question. Many experts believe that the installation of a stabilizer is a mandatory measure, while others are of the opinion that it is necessary only if there are constant voltage interruptions.
Double conversion stabilizer
Ideal for modern LCD TV panels. They are superior in all properties to the above systems. They are silent, durable, withstand large voltage drops.
What is stabilizer
A stabilizer is a device that helps equalize voltage. It protects against overvoltage or undervoltage surges to medium voltage. In case of strong drops, it turns off the equipment, thereby protecting it from burnout.
But you should be aware that not every stabilizer for a TV copes with the task at hand, since most are designed for light loads. Therefore, an important factor when choosing is the power of the device. It is believed that a system for 500, 220, 1000 W is quite enough for LCD TVs. Read also how to measure TV diagonal in inches and centimeters using a table and a convector.
Relay stabilizers are in demand due to their budgetary cost. They are able to withstand a fifteen percent power surge.
One of the main disadvantages is quick wear. And also many relay systems are very loud, so it is recommended to use them only as a temporary option.
The disadvantage is the fact that thyristors can fail at high temperatures.
What are the stabilizers
There are four types of stabilizers, they differ in structure, technical properties:
- relay type;
- mechanical type;
- seven-story (teristor) type;
- double conversion devices;
In order to decide whether you need a stabilizer and if so, which one is better to choose, you need to take into account many factors: budget, how often there are voltage drops.
This type is in many ways superior to the relay mechanism in all respects. But it was not without its drawbacks: the mechanical system works quite slowly, and you also need to often change the brushes in the service.
What to look for when choosing a stabilizer?
In order for the purchase of an additional device to be justified, and the stabilizer to serve for a long time, you need some points from Honor:
- Determine how necessary the purchase of such a device is. If the jumps in current intensity are small or extremely rare, then some power supplies are quite capable of withstanding them. In this case, you can get by with the protective system of the unit itself.
- It is advisable to look for a device with additional protection against short circuits and a system for cleaning the network from interference.
- Dimensions of the device.
- Ways to connect to the network and to devices.
- Noise during operation.
- Device power. One of the important indicators, since if the power of the control device is less than the TV indicator, then the meaning of this purchase will be reduced to zero. Therefore, before choosing a stabilizer, you need to see what the power of the TV is. Typically, this information is indicated in the technical data sheet or on the back of the case. Based on the power indicator of the TV or its power supply, it is necessary to choose a stabilizer that has high power.
- The number of connected equipment representatives and their total power value. In order to connect the control system to several devices, it is necessary to summarize the power indicators of all devices and, based on these data, choose a voltage regulator.
Voltage stabilizer for TV: how to choose what you need for?
Why do some sellers advise buying a voltage stabilizer when buying a TV? How to choose this unit, and is it really necessary? A sudden blackout and voltage drops are unpleasant, but common. Horse racing most often happens:
- when the cable is broken;
- when using powerful equipment (for example, a welding machine for a construction site);
- temporary power outage.
Voltage regulation devices for different types of TVs
Some buyers mistakenly believe that if you choose a voltage regulator for LCD TVs, then it cannot be used, for example, for a plasma receiver. In fact, this is not the case. Regulators are universal units capable of connecting to any type of equipment, including any type of TV. Any of the representatives of the devices for regulating the current intensity indicators can be used to connect to any TV. The choice of the type of regulator depends only on the power of the TV. So, for various stereos and home theaters, you will need a more powerful unit than for a conventional TV. At the same time, there are special models of such devices from the manufacturers themselves Phillips, LG, Samsung, but often they have a cost that significantly exceeds the cost of a conventional stabilizer.
Do power surges affect household appliances?
Of course, small fluctuations cannot have a special effect on the condition and serviceability of equipment. But if we are talking about a sharp jump in voltage, then such a phenomenon can damage the TV’s power supply and the device itself. In this case, it is better to secure it by connecting a stabilizer.
What is a voltage regulator?
This is a special device designed to analyze the indicators of the incoming voltage and equalize it, if necessary, up or down, converting it into standard 220V.
According to the principle of operation, stabilizers are:
Overview of regulator models and their characteristics
This review presents models of inexpensive devices
- DefenderAVRInitial series 1000. Inexpensive automatic regulator with a power of 320 watts. Equipped with an overheating and overload protection system, as well as a built-in surge protector. Compact device with indicator of the current network status.
- DefenderAVR iPOWER model A medium-sized electronic device with a power of 300 watts. Provides high-speed operation, quiet.
- SvenNeo R 600. Stabilizer capable of converting current intensity to 220V at an input value from 150 to 280V. The device is equipped with an additional function for filtering high-frequency interference. This is especially important for sensitive devices such as televisions. This device will automatically shut down when overload, overheat and short circuit.
- Uniel STR500 power 300 W. Convenient and compact regulator with a maximum power of 300 W. Able to align indicators of current intensity in the network from 145 to 280V at the input. Equipped with an indicator that shows the status of working voltage and overload.
It should be noted that the purchase of regulators for each separate type of equipment is not advisable. Therefore, to provide protection against drops of all household appliances in the house, it is better to purchase a more powerful wall stabilizer. Such devices are distinguished by high power (about 8000 W) and are able to withstand significant voltage and load fluctuations.
If we are talking only about protecting an expensive TV or home theater, then in this case it is better to purchase a special small power regulator which will be enough for one device. Some television receivers have built-in stabilizers, but the power supplies of modern televisions are unable to completely protect the device from sudden and significant voltage surges. Therefore, the purchase of a stabilizer may significantly extend the life of the device.
