PH7777-series digital power factor meter

Summary&application: 

PH7777-series digital power factor meter is mainly applied for the real-time measurement and display for power factor and phase value in the single/three phase electrical circuit, realizing remote transmission for the measured electrical quantity data through RS485 interface or analog quantity transmitting interface, characterized with high measurement accuracy, good stability, free adjustment for long period of work, parameters to be set at site, etc.


1.Main functions and characteristics

◆It can measure and display single/three phase power factor value in the electrical circuit.

◆Extendible for analog quantity output function, transmitting specification of 4~20mA, 0~20mA, 0~10mA which is optional.

◆Extendible for switch quantity output function for the relay, realizing upper/lower-limit alarming output.

◆Extendible for RS-485 communication interface, adopting the standard ModBus-RTU communication protocol and the baud rate can be set.

◆Parameters including current/voltage ratio of the meter, upper/lower-limit alarm value, alarming return difference, communication address of the meter, baud rate, transmitting output mode, transmitting output range, etc. are programmable.
