Carlo Gavazzi Voltage Monitoring Relay Code PPB01CM44

The Carlo Gavazzi voltage monitoring relay can operate on both 3Ph and 3Ph+N mains detecting, besides the phase loss and the correct phase sequence, possible overvoltages and undervoltages. The power supply is provided by the monitored mains is wide input range and switch mode. A delay on alarm, up to 30s, for the over/under voltage alarms, filters unwanted trippings for temporary conditions.

Wide input voltage range and frequency
Over and under voltages are adjustable from + or - 2 to 22% of the selected range
Switch mode power supply
Output LED indication
22.5mm standard DIN enclosure
Relay contact output for indication of the alarms/output status
