AC Voltage Protection Relay

  IMPORTANT:  

The UVR500 AC under voltage relay has entered our Stage V product migration and phase-out program.

Production of this relay has been discontinued, but limited stocks remain available to order on a first-come first-served basis until Friday 31st March 2017. After that date, or beforehand if all stock is depleted, we reserve the right to withdraw supply of this item. Please contact us to check stock availability.

UVR500 AC voltage relay, 3phase and neutral, 230VAC - click to enlargeThe UVR500 is a DIN rail or surface mountable relay for the voltage monitoring and protection of AC mains or generator systems.

The UVR500 monitors a 3 phase and neutral AC power supply. The internal DPCO relay de-energises if any phase-neutral voltage falls below the front facia "trip volts" setting (adjustable 160 - 240VAC Ph-N). A "differential volts" setting (2 - 26VAC) allows control over the relay energisation voltage.

The relays can be used for the monitoring of AC mains/genset failure or under voltage, for the control of load contactors, and for triggering automatic start of a diesel generator, pump or other backup equipment.

Features:

  • AC under voltage protection
  • 3 phase & neutral connection
  • Front facia "trip volts" adjuster sets relay de-energisation
  • Front facia "diff volts" adjuster sets relay re-energisation
  • DPDT relay outputs, rated 5 Amp @ 240 VAC
  • LED indication of relay state
  • DIN rail/surface mout case, screw terminals
