PQMII-T20-C-A

PQMII is ideal when continuous monitoring of three-phase systems is required. It provides metering of current, voltage, actual and reactive power, energy use, power cost, power factor and frequency. Programmable setpoints and 4 assignable output relays allow the addition of control functions for specific applications. This includes basic alarms for current or voltage over/under, unbalance, demand-based load shedding, and capacitor power factor correction control. More complex control can be achieved with four switching inputs, which can also be used for circuit breaker on/off, flow information, etc
The Voltage Disturbance Recorder (VDR) monitors voltage surges (voltage surges) and voltage spikes (voltage rises) with a capacity of 500 voltage drop/voltage rise events. DNP 3.0 communication protocol standard features
