ac voltage stabilizer working: 1 kva automatic voltage stabilizer
Automatic voltage regulator is when the grid voltage is unstable or the load power changes, the automatic control circuit drives the servo motor according to the output voltage change, adjust the position of the carbon brush on the contact auto-voltage regulator, so that the output voltage is adjusted to the rated value, to achieve automatic voltage regulation. In short, it is to keep the changing voltage in a stable range through the voltage regulator to ensure the normal operation of electrical appliances.
First, the input of AC voltage regulator is connected to the switchboard(three-Phase Automatic Voltage Stabilizer For Home), and a fuse conforming to the power protection rate of voltage regulator is installed on the user's switchboard to ensure the safety of electricity use.
Second, connect the power supply of the electrical equipment to the output terminal of the AC voltage regulator, and pay attention to the rated input voltage value of the electrical appliances should be consistent with the output of the voltage regulator, do not connect wrong.

Third, first open the ac voltage regulator power switch, work indicator light. Observe whether the voltmeter indication is normal. When the output voltage is normal, then turn on the power switch of the electrical equipment, the voltage regulator can automatically adjust the voltage, normal power supply.
Fourth, when the electrical equipment is not used for a long time, please turn off the power switch of the electrical equipment, in order to reduce power consumption and extend the service life of the AC voltage regulator.
Fifthly, ac voltage regulator should not overload. When the power supply voltage is low, the output capacity is reduced and the load of voltage regulator should be reduced accordingly.
Sixth, when electing to use electric appliances with refrigerator, air conditioner, water pump and other equipment with motor running, should choose the AC voltage stabilizer with more than 3 times capacity, so as to avoid the equipment starting current exceeding the voltage stabilizer fuse current or over-current protection circuit breaker current that makes the voltage stabilizer fuse to fuse or circuit breaker trip or the voltage drop is too big to work.
Seventh, the wire connected to the AC voltage regulator should have enough loading surface to prevent heat and reduce pressure drop. Voltage regulators with a capacity of more than 2KVA are connected with terminals. A single copper wire should be used, and terminal screws should be tightened as far as possible to prevent heating at the connection.
Eighth, whether single-phase or three-phase AC voltage regulator, after all the input and output lines are connected, should first turn off the load power switch, then turn on the voltage regulator, check the output voltage is normal, then turn on the load power switch.
