DPC01DM48 DPC01 voltage monitoring relay, triple-phase, 380 - 480 V AC

DPC01 and PPC01 are three-phase mains monitoring relays. They can be operated on both the 3P and 3P+N mains and, in addition to the phase failure and the correct phase sequence, can detect possible overvoltages, undervoltages, unbalance and deviation. The supply voltage for the monitoring relays is supplied via the monitored mains. Two independent alarm time lags of up to 30 seconds can be set for overvoltage/undervoltage alarms and unbalance/deviation alarm messages.
