How To Choose Power When Buying A Voltage Stabilizer

When purchasing Automatic Voltage Stabilizer, the method of selecting the power used:

The output power of the voltage stabilizer produced by the domestic voltage stabilizer factory is the maximum power. The nominal power of household appliances refers to the active power, and the inductive loads such as refrigerators, air conditioners, and water pumps have a large current at the moment of startup, so refrigerators, air conditioners, and water pumps are rated at power x (3 to 5 times).

For example: 3-horsepower domestic air conditioners (220V electricity). 1 horsepower is equal to 0.75 kilowatts * 3 horses = 2.25 kilowatts * 3 times the inductive load starting current = 6.75 kilowatts. The above voltage stabilizers are applicable. (Air conditioning maintenance and installation technicians recommend the use of 8KVA voltage stabilizers)

Based on professional water and electricity installation technicians and factory professional electricians, engineers and voltage stabilizers, the power calculation method is:

General industrial equipment uses the rated power at least twice the rated power. When used on equipment with motor operation, high current starting devices and impact loads, a voltage stabilizer with a capacity of more than 3 times should be selected to avoid excessive starting current and power supply line voltage reduction and inability to work normally.

For example: a steam pump machine (380V electrical equipment) in a factory has a motor power of 7.5 kilowatts. However, when it starts to run and the surge current exceeds 3 times of the motor power, a voltage stabilizer with a power greater than 3 times must be selected.
