Precautions for reasonable installation, use and maintenance of voltage stabilizer

First, connect the input of the power distribution board, and install a fuse that meets the power guarantee rate of the instrument on the user power distribution board to ensure the safety of electricity use.

Second, connect the power supply of the electrical equipment to the output terminal of the instrument. Note that the rated input voltage of the electrical equipment should be consistent with the output of the voltage regulator, and do not connect it wrong.

Third, first turn on the power switch and the working indicator lights. Observe whether the indicated value of the voltmeter 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 to reduce power consumption and extend the life of the regulator.

Fifth,  must not be overloaded. When the mains voltage is low, the output capacity decreases, and the load on the regulator should be reduced accordingly.

Sixth, when selecting appliances such as refrigerators, air conditioners, water pumps and other motors, voltage regulators with a capacity of more than 3 times should be selected to prevent the device starting current from exceeding the regulator fuse current or overcurrent protection circuit breaker current to stabilize The fuse of the voltage transformer blows or the circuit breaker trips or the voltage drop is too large to work.

Seventh, the wire connected to the voltage regulator should have enough load surface to prevent heat generation and reduce voltage drop. Voltage stabilizers with a capacity of more than 2KVA are connected by terminals. A single copper wire should be selected, and the terminal screws should be tightened as much as possible to prevent the connection from heating.

Eighth, whether it is a single-phase or three-phase voltage regulator, after connecting all input and output lines, the power switch of the load should be turned off first, and then the voltage regulator is turned on. After checking that the output voltage is normal, then turn on the power switch of the load .

8 precautions for the use of voltage regulators
1. Do not use excessively high loads;
2. Please use enough wires;
3. Please carefully connect the input voltage and the output of the equipment;
4. The output voltage of instruments and should be unified;
5. Please choose the same input voltage switch as the power supply voltage;
6. If the fuse is burnt out, please check the load equipment;
7. Use fuses of the same rating, not non-rated fuses or wires;
8. Install in a dry and ventilated place.
