PQM II
Power Quality Meter
The PQM II is an ideal choice when continuous monitoring of a three phase system is required. It provides metering for current, voltage, real and reactive power, energy use, cost of power, power factor and frequency. Programmable setpoints and 4 assignable output relays allow control functions to be added for specific applications. This includes basic alarm on over/under current or voltage, unbalance, demand based load shedding, and capacitor power factor correction control. More complex control is possible using the 4 switch inputs which also can be used for status such as breaker open/closed, flow information etc.

New In Version 2.10:
  • Voltage Disturbance Recorder (VDR) to monitor voltage dips (voltage sags) and voltage spikes (voltage swells) with capacity for 500 sag/swell events.
  • DNP 3.0 Communications Protocol standard feature.

Features and Benefits
  • Mounting Versatility
  • Keypad with large illuminated 40-character display
  • Any assignable output may be used to trigger an alarm
  • May be connected to DCA or SCADA systems
  • Flash upgradable

Applications
