What Are The Characteristics Of An Automatic Voltage Stabilizer?

Automatic Voltage Stabilizer (single-phase 0.5kVA~3kVA, 10k horizontal and below, three-phase 9kVA and below) When the input phase voltage is lower than 198V, the output capacity begins to decrease; when the input phase voltage is equal to 160V, it drops to 50% of the rated capacity of the voltage stabilizer. Therefore, special attention should be paid to reducing the load and derating at the low end of the power supply voltage to avoid overloading and burning the voltage stabilizer;
The automatic voltage stabilizer can output 220V and 110V voltages at the same time. But even when all outputs are 110V, the load carried by the voltage stabilizer cannot exceed 50% of the rated capacity, otherwise it is overloaded.
⒈ Connect the input of the voltage stabilizer to the distribution board, and install a fuse that meets the power protection rate of this instrument on the user's distribution board to ensure safe power consumption.
⒉ Connect the power supply of the electrical equipment to the output terminal of this instrument. Note that the rated input voltage value of the electrical appliance should be consistent with the output of the voltage stabilizer. Do not connect it wrongly.
⒊ First turn on the power switch of the voltage stabilizer, and the working indicator light will be on. Observe whether the voltage meter indication value is normal. When the output voltage is normal, turn on the power switch of the electrical equipment, and the voltage stabilizer can automatically adjust the voltage and supply power normally.
⒋ When the electrical equipment is not used for a long time, please turn off the power switch of the electrical equipment to reduce power consumption and extend the service life of the voltage stabilizer.
⒌ The ​​voltage stabilizer must not be overloaded. When the mains voltage is low, the output capacity is reduced, and the voltage stabilizer load should be reduced accordingly.
⒍ When the selected electrical appliances include refrigerators, air conditioners, water pumps and other equipment with motors, a voltage stabilizer with a capacity of more than 3 times should be selected to prevent the starting current of the equipment from exceeding the fuse current of the voltage stabilizer or the current of the overcurrent protection circuit breaker, causing the voltage stabilizer fuse to melt or the circuit breaker to trip or the voltage drop to be too large to work.
⒎ The wire connected to the voltage stabilizer should have sufficient load surface to prevent heating and reduce voltage drop. Voltage stabilizers with a capacity of more than 2KVA use terminal connection. A single copper wire should be selected and the terminal screws should be tightened as much as possible to prevent heating at the connection.
⒏ Regardless of whether it is a single-phase or three-phase voltage stabilizer, after connecting all input and output lines, you should first turn off the power switch of the load, then turn on the voltage stabilizer, and after checking that the output voltage is normal, turn on the power switch of the load.
