- The three-phase voltage regulator consists of three sets of single-phase voltage regulators, which are independently regulated by phase separation and have high output precision. It is an ideal regulated power supply for three-phase equipment. The following is the manufacturer of the power adapter manufacturer
The three-phase voltage regulator consists of three sets of single-phase voltage regulators, which are independently regulated by phase separation and have high output precision. It is an ideal regulated power supply for three-phase equipment. The following is the manufacturer of the power adapter manufacturer:
1. Connect the instrument input to the power distribution board and place the fuse on the power distribution board to ensure safe use of electricity.
2. Connect the power supply of the electrical equipment to the output of the instrument. Note that the rated input voltage of the appliance should be the same as the output of the regulator, and it should not be misconnected.
3. First turn on the power switch of the regulator, the work indicator lights up, and observe whether the voltmeter indicates normal. When the output voltage is normal, the voltage regulator can automatically adjust the voltage and provide normal power by turning on the power switch of the electrical device.
4. When the electrical equipment is not used for a long time, please turn off the power switch of the power supply to reduce power consumption and extend the life of the regulator.
5. The voltage regulator must not be overloaded. When the voltage is low, the output capacity is reduced, so the load on the regulator should be reduced accordingly.
6. When the electric appliance has a motor operated device such as a refrigerator, an air conditioner, a water pump, etc., the capacity of the regulator should be selected more than three times to avoid the device starting current exceeding the regulator fuse current or the overcurrent protection circuit breaker current, so that the regulator fuse or The circuit breaker tripped or the pressure drop was too large to work.
7. The conductor connected to the regulator should have sufficient load surface to prevent heating and reduce pressure drop. A voltage regulator with a capacity exceeding 2KVA is connected by a terminal. A single copper wire should be selected and the terminal screws should be tightened as much as possible to prevent heat build-up at the joint.
8. The three terminals A, B and C on the left side of the voltage regulator are connected to the three-phase line, the three a, b and c on the right are connected to the load, and the intermediate terminals are connected to the input and output neutral lines.
9. The voltage detection switches on the three-phase voltage regulator panel do not indicate the AB and AC phase line voltages based on the arrival time, respectively.
The above is the application of high-power power shared by the joint power adapter manufacturers, I hope to help everyone.
