Product Description
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.
- The monitoring relay can be used from 100 to 690 V AC and from 50 to 400 Hz
- Adjustable voltage levels and time lag lets you respond to alarm conditions
- LED display for the operating status, alarm and relay status
- Two mounting versions are available as DIN rail (DPC01) or plugin module (PPC01)
- Adjustable ON delay to prevent faults during starting or starting up
- High immunity for noisy environments
- Three-line (3P) or four-line (3P + N) three-phase mains monitoring
- Detecting correct phase sequence, phase loss, unbalance and deviation
- Setpoints for overvoltage and undervoltage, unbalance and deviation can be adjusted using the front adjustment wheel
- Time delay
- Two changeover relay outputs
