Installation precautions for AC voltage stabilizer


First: Connect the voltage stabilizer input to the distribution box, and install a fuse that meets the power of the power supply on the user distribution box to ensure the safety of electricity.


Second: The air switch on the power distribution box of the voltage stabilizer selects the D type air switch. Many users use the C type air switch, and the voltage stabilizer trips as soon as it is turned on.


Third: Connect the power supply of the electrical equipment to the output terminal of the voltage stabilizer. Note that the rated input voltage value of the electrical equipment should be consistent with the output of the voltage stabilizer.


Fourth: Turn on the power switch of the voltage stabilizer first, the working indicator light is on, and observe whether the indicated value of the voltmeter is normal. When the output voltage is normal, turn on the power switch of the electrical equipment, and the voltage regulator can automatically adjust the voltage and supply power normally.


Fifth: 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.


Sixth: The voltage stabilizer must not be overloaded. When the mains voltage is low, the output capacity will be reduced, so the load of the voltage stabilizer should be reduced accordingly. If the input voltage is lower than 200V, the load of the regulator should not exceed 70%; if the input voltage is lower than 180V, the load of the regulator should not exceed 50%.


Seventh: When selecting electrical appliances such as refrigerators, air conditioners, water pumps and other equipment with motors running, a voltage stabilizer with a capacity of more than 3 times should be selected to prevent the equipment starting current from exceeding the voltage stabilizer fuse current or the overcurrent protection circuit breaker current to stabilize The voltage fuse is blown or the circuit breaker is tripped or the voltage drop is too large to work.


Eighth: The wire connected to the voltage stabilizer should have enough load surface to prevent heat generation and reduce voltage drop. Voltage stabilizers with a capacity of more than 3KVA are connected by a terminal block, a single copper wire should be used, and the terminal screws should be tightened as much as possible to prevent the connection from heating.

Ninth: Whether it is a single-phase or three-phase voltage stabilizer, after connecting all input and output lines, turn off the power switch of the load first, then turn on the voltage stabilizer, and then turn on the power switch of the load after checking that the output voltage is normal .


Summary: The service life of the voltage stabilizer is closely related to the use and maintenance of the customer. Properly maintained, it can be used for more than ten years, and the wrong installation and use method can only be damaged after one to two years.


Precautions for using AC voltage stabilizer


1. Don't overuse the load, preferably 70% of the voltage stabilizer, and 50% of the voltage is the best;


2. The input and output cables must meet the rated requirements;


3. Please carefully connect the input wiring of the regulator and the output wiring of the regulator;


4. The output voltage of the instrument and the voltage regulator should be unified;


5. Please choose the input voltage switch to match the voltage regulator switch current; note that you must use a D-type air switch;


6. If the fuse is burned out or the switch is tripped, please check the power of the load equipment;


7. To use the same rated fuse, can not use non-rated fuse or wire;


8. Install in a dry and ventilated place; leave a space of one meter around the equipment to facilitate future maintenance;


9. Dust removal once every six months.
