Air-conditioner Three Phase Voltage Monitoring Relay , phase protection relay

JVR800-2 is multi-functional monitoring and protection device which includes timing, counting and voltage show, over-voltage and under-voltage protection, open phase protection and phase sequence protection.

It uses advanced microprocessor chip and nonvolatile storage technology. LCD display is easy to operate

It can record working times and working hours, fault times and hours, show the current supply voltage

Cut off power to protect the equipment when meet over-voltage and under-voltage, phase loss and phase reversal faults

It is widely used in passenger elevator, hoist , machine tool and other device which frequent start for protect the voltage and phase to make sure equipment working

Fault Record: Three-phase power protector | Power protector adopts non-volatile memory technology. When overvoltage, undervoltage, phase loss, unbalance, or phase sequence fault occurs, faults are recorded. Even if the product is completely powered off, the fault can be memorized. Information, convenient troubleshooting.
