Carlo Gavazzi DUB01CD48500V Voltage Monitoring Relay, Over or Under Voltage, 2 to 500 V AC/DC

The Carlo Gavazzi DUB01CD48500V is a single phase voltage monitoring relay that detects over voltage or under voltage on AC or DC circuits from 2 to 500 V. It measures true RMS voltage, and the set point, hysteresis and alarm delay are adjusted on front knobs. It is commonly used to watch battery, DC bus and control supply voltages and trip an alarm before equipment is affected.
