Use the PowerWatch as your first line of defense against power
quality problems. Simply plug it into any power receptacle
(120-volt North American or 220/240-volt Australian, European or
UK) and begin monitoring and recording essential voltage
disturbance information-surges, sags, outages, impulses,
dropouts, and frequency variations. Set up your pre-determined
disturbance threshold values or use the industry standard
default values using PowerWatch software. No wiring or dangerous
connections are required. |
