Picture

YC7VAN Overvoltage and Undervoltage Protector

Voltage and current display relay is a microprocessor-based voltage monitoring device for sinale-phase AC networks to protect electrical equipment from surge voltage. The device analyzes the main voltage and displays its curent value on a digital indicator. Load is switched by electro magnetic relay. The user can set the current voltage value and delay time through the button.The value is stored in non-volatile memory. Aluminum wires and copper wires can be used for connection.

1. In caseofover-voltagefault, under-valtagefault orover-current tault insingleghaseline, the product canpower line over a time delay after voltageor current of the lineis recovered to normal condition.

2. In case of transient over voltageinline, the product canprotect the equipmant from false aperation.

3. In case that theline subjects to unstable Voltage connectionand other fault, the product willdisconnec theline.

4. When fault vollage of thelinereaches thepeak, the product it self will not bedamaged.
