YUMO NP4-V OVERVOLTAGE AND UNDERVOLTAGE PROTECTOR 40/63A 80~400VAC

An OVERVOLTAGE AND UNDERVOLTAGE PROTECTOR is an electrical equipment protection device that triggers a protection mechanism when voltage exceeds or falls below a preset value. It is mainly used to prevent voltage fluctuations from damaging electrical equipment or causing safety hazards.In power systems, voltage fluctuations are always inevitable. In the case of overvoltage, equipment may suffer electrical shock or burnout, while in the case of undervoltage, equipment may fail to operate. The OVERVOLTAGE AND UNDERVOLTAGE PROTECTOR can automatically monitor voltage and trigger a protection mechanism when the voltage exceed the set range, cutting off the circuit and protecting the electrical equipment.The OVERVOLTAGE AND UNDERVOLTAGE PROTECTOR is widely used in various fields, such as power systems, industrial automation, building automation, and traffic signal control systems. It is characterized by easy installation, convenient operation, high sensitivity, fast response and efficient equipment protection, preventing voltage fluctuations from damaging electrical equipment.

Application Method

1. Connect the measure voltage to the 1 and 2 terminal

2. Connections of meter with internal current transformer as graph 1. Make the wire through the hole in the meter and the direction chose arbitrarily.

3. Connections of meter with external current transformer as graph 2. Make the wire through the hole in the meter, and connect the two wires of the secondary transformer to the 3 and 4 terminal.

4. When power on, the meter display the measure parameters.

5. When power on, you can press the button of SAM CK last for 5 seconds, then the electric energy will to be zero and start to cumulate when release the button. And when power off, the meter can save the value of electric energy and go on cumulating data when the meter power-on next.
