ACR PowerWatch

Voltage Disturbance Recorder (VDR)

ACR PowerWatch Voltage Disturbance Recorder

ACR PowerWatchDo you have equipment failing repeatedly or behaving strangely? Expensive out of warranty repairs due to voltage surges? Get to the root of the problem by measuring your incoming mains voltage and recording every surge, sag, spike and dip that happens.

PowerWatch 220/240V is the easiest way to monitor and record critical voltage disturbance information from any 220/240 volt Australian power outlet. Just set up your pre-determined voltage threshold values, or use the industry standard default values, and plug it in to a GPO power point. No wiring or dangerous connections required.

The data you record with the PowerWatch can be easily presented to your electricity authority or building manager, for discussion and complaints about power quality.

Applications:

  • Troubleshooting repeated equipment failures
  • Medical and scientific equipment
  • Point-of-sale terminals
  • Computers
  • Other sensitive electronic equipment
