Specifications

1. waveform Power meter display voltage, current, power, Hz, kWh, kvarh, 63rd harmonic
2. 4DI/ 4DO, RS485,Ethernet

PMAC760 ethernet analog power meter with following features:

 

PMAC760 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 RS485 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 input. A front panel RS232 communication ports can be connected to PC for simultaneous access of information by other plant personnel.

 

Features:

• Realtime parameters measuring
• Two-way/ four-quadrant energy display
