3 PHASE VOLTAGE CONTROL RELAY
The phase failure relays are designed for applications where a three-phase system needs to be monitored for unbalance or deviation in balance voltage. The relays includes a standard timing function. In addition the PADI and PANI offers a true time delay on drop out even at total power failure. The relay works in “fail safe”mode and need no external power supply. If an external stable power supply is available the 45mm housing offers seperate terminals for internal power.
