CE Certification 72*72mm Digital Power Factor Meters

Model NO.: DM72-H G./N: 11.8/10.8kg Specification: CE, ISO Size: 72*72mm Trademark: cnsckj Origin: Zhejiang Single Phase Power Factor Meter

Function:
Measure and digital display on single-phase/three-phase power factor or phase value of electric wiring. The power factor Meter can see the frequency and phase value, and phase meter can see frequency and power factor value through the keyboard. Switching value output (higher and lower limit alarms) modules, analog value transmitting output module, RS485 communication module are optional offered.
It can conveniently realize the setting of many parameters including higher and lower limit alarm value, alarm return difference, communication address and communication baud rate, transmitting output specification, transmitting output range by the keyboard of instrument.
