Phase Failure 3 Phase Power Monitor Relay JVRD-W 480 Vac For Compressors

Description:

The Phase and voltage monitoring relay JVRD-W is Miniature size and low weight,always be used in Pump / Fans / Blowers / Motors / Compressors etc.Protective the three phase power and keep the equipment working when it happened Phase sequence / phase loss / over voltage / under voltage or Phase unbalance , is the directly ways to prevent the equipment broken of the question above

Adjustable functions : With the Knob in the shell , the user can adjust the over voltage range and under voltage range by himself to choose the suitable voltage range that the most needed

Alarm functions: The five LED lights for satus indication the phase loss / phase reverse / under voltage / over voltage /normal , You can check the circuit situation from it to Monitor the euipment safely

The reversed phase sequence of the power supply reversed the accident or equipment damage. Such as elevators, central air conditioning, cranes, motors, etc. If the phase sequence of the power supply is wrong after repair, it will lead to accidents. The phase sequence protector must be connected to the control circuit to ensure the phase sequence is correct. Air-conditioning compressors also use phase sequence protectors to ensure that the compressor will not be reversed after maintenance

When the phase sequence protector generates power overvoltage, undervoltage, phase loss, phase error, unbalance, etc., the LCD flashes overvoltage, undervoltage, phase loss, phase sequence, unbalance, etc. If the time exceeds the set operating time, words such as overvoltage, undervoltage, phase loss, phase sequence, and unbalance will remain on. At the same time, the voltage value at the time of fault will be displayed. At this time, the output contacts will be switched.
