1. The function of the voltage stabilizer: 1. It can stabilize the voltage of low voltage 125V-165V or high voltage 250V-270V between 200-230V, so that household appliances can work normally;
2. When the input voltage is higher than 255-275V or lower than 125-160V, the power supply can be automatically cut off;
3. When there is a sudden call after a power failure, the output power can be started after a delay of 5-8 minutes to avoid damage to the electrical appliance due to excessive voltage. When purchasing a household voltage stabilizer, you must pay attention to whether the above three basic functions are complete or not.
2. Classification of voltage stabilizers: The first is the manual voltage stabilizer, which has basically been eliminated because of inconvenient operation.
The second is the automatic voltage stabilizer:
(1) Polar automatic voltage stabilizer: The high-grade voltage stabilizer uses a servo motor to control the voltage. Its advantages are that there is no instantaneous power failure, the output voltage is stable, and the general voltage stabilization accuracy is 3-5%. It is suitable for high-end and high-voltage electrical appliances, such as computers and testing equipment.
(2) Relay-type automatic voltage stabilizer: The output voltage is adjusted by switching the relay, the voltage fluctuation is large, and the accuracy is relatively low. It is used for mid-range voltage stabilizers, such as Yalang TM series high-power switching automatic AC voltage stabilizers. These products have high stability and low price, and are suitable for equipment that does not require high voltage accuracy.
Third, the principle of voltage stabilizer purchase:
When buying a voltage stabilizer, it is recommended that you at least buy a voltage stabilizer with a power three times larger than the actual power, because the voltage stabilizer must overcome the surge shock of the mains and the starting shock of the inductive load (such as refrigerators, air conditioners, etc.) in actual work. , motors and electric motors).
When the voltage stabilizer is used in an inductive load, due to the large instantaneous starting current of the inductive load, it is generally about 3-5 times of the rated current and often exceeds 9 times of the running current (such as refrigerators, air conditioners, washing machines, fans, large Air conditioners, printing presses, air compressors, elevators, water pumps, etc. are all inductive loads), so any voltage stabilizer equipped with inductive loads such as motors and compressors must consider its power reserve. Sufficient margin should be reserved to avoid immediate damage to the voltage stabilizer caused by the inrush current generated when the load is turned on. If the whole plant uses a voltage stabilizer, when starting the machine, avoid high-power inductive loads from starting at the same time, so when purchasing a voltage stabilizer, there should be 1.5 times the reserved capacity. 3 times.
● When choosing a voltage stabilizer, you should also pay attention to choosing products with high brand awareness, because these manufacturers have reliable quality and considerate service; at the same time, whether the manufacturers have good after-sales service, such as product quality implementation of three guarantees, etc., is also what consumers should pay attention to important factor. If the boat wave regulator is a product underwritten by the People's Insurance Company of China, it can be used with confidence.
When wiring, put the cooking appliances on one line (induction cooker, water heater, etc.). Put the household appliances on one line (air conditioner, refrigerator, fan) and then route the TV, computer, etc. all the way. .. The main function of the voltage stabilizer is that the mains is unstable and the fluctuation (150~250V) cannot be stabilized at a number for a long time. It is only necessary. Generally, it is not necessary at 220V, , plus or minus 5V. Unless , often time is lower than 220V, then you should consider one. If you use it, you may not use all the equipment in your home. The more expensive electrical appliances are used, the others are not necessarily, you can look at the manual, above There are voltage ranges.
