High-precision fully automatic AC household voltage stabilizer

Description

■ Do household appliances need to be equipped with a voltage stabilizer?

Because some household appliances contain coil components, household appliances will generate eddy currents that hinder current at the beginning of power-on. The generation of eddy currents will not only weaken the instantaneous voltage when the appliance starts, resulting in slow startup, but also strengthen the instantaneous voltage generated after the circuit is broken, which may cause sparks and damage the circuit. Therefore, it is necessary to use a voltage stabilizer for voltage stabilization.
In addition, household voltage stabilizers have a delayed output function. When the power is suddenly restored after a power outage, the delayed output of the household voltage stabilizer can protect the compressors of air conditioners and refrigerators. Because the compressors of refrigerators and air conditioners suddenly lose power when working, the local pressure in the pipelines of the machine is very high. When the power is restored immediately, the compressor is difficult to start and is easily overheated and burned. If it is started after 5 to 10 minutes, the pressure in the machine will gradually spread evenly, which can protect the compressor.

■ Principle of household voltage stabilizer

The household voltage stabilizer consists of voltage regulating circuit, control circuit, and servo motor. When the input voltage or load changes, the control circuit samples, compares, and amplifies, and then drives the servo motor to rotate, so that the position of the voltage regulator carbon brush changes, and the output voltage is kept stable by automatically adjusting the coil turns ratio. 5000VA and above voltage stabilizers also work on the principle of voltage compensation.

■ Advantages and uses

The SVC (TND, TNS) series of household voltage stabilizers have wide voltage range, high voltage stabilization accuracy, delayed output protection, beautiful appearance, and small size. It has the characteristics of no waveform distortion, reliable performance, and long-term operation. It is equipped with overvoltage protection function. According to user needs, undervoltage, delay and other protection functions can be set.
It is widely used in any electrical places such as home computers, audio equipment, air conditioners, refrigerators, computers, monitoring equipment and test equipment, lighting systems, communication systems, medical equipment, industrial automation equipment, etc. It is an ideal voltage stabilizer.

■Precautions for use

This series of voltage stabilizers should be used indoors, and the normal use conditions are:
1. Do not use too high a load;
2. Please use enough wires;
3. Please carefully connect the input voltage and the output of the instrument and equipment;
4. The output voltage of the instrument and equipment and the voltage stabilizer should be unified;
5. Please select the input voltage switch to be the same as the power supply voltage;
6. If the fuse burns out, please check the load equipment;
7. Use the same rated fuse, and do not use unrated fuses or wires;
8. Install in a dry and ventilated place;
