Voltage too high or too low? Stay prepared with an OVR⚡
An Over & Under Voltage Monitoring Relay detects when the supply voltage moves outside the set limits, causing the relay output to respond when overvoltage or undervoltage conditions occur.
Choose between an option for single-phase AC and DC voltage monitoring, or a three-phase option with additional monitoring for phase failure, phase sequence and asymmetry.
Compact, DIN-rail mounted and adjustable for different applications, an OVR is a practical addition to electrical panels where reliable supply monitoring matters.
