Specifications
1. Waveform Power meter display voltage, current, power, Hz, kWh,
kvarh, *3rd harmonic
2. 4DI/ 4DO, RS**5 Modbus-RTU, Ethernet
PMAC**0 Power Quality Analyzer, Ethernet Power Meter with following features:
PMAC**0 is designed for monitoring and displaying electric parameters include Current, Voltage, Active/ Reactive/ Apparent power, Power factor, Frequency, Active/ Reactive energy. This also includes basic alarm on over/ under current or voltage, unbalance, demand based load shedding, and capacitor power factor correction control. All monitored values are available via two digital RS**5 communication ports running the Modbus protocol. If Analog values are required for direct interface to PLC, any of the monitored values can be output to one of 4 isolated analog outputs. A process variable can be measured using an analog . A front panel RS**2 communication ports can be connected to PC for simultaneous access of information by other plant personnel.
