PS/PQ7777 digital power meter
Measure and display the single/three phase active power\reactive power in the electric lines with digital direct reading method. Both 3 phase 3 wire and 3 phase 4 wire signal input method are allowed. The meter can be used as normal digital wattmeter\varmeter, it can also be used as active/reactive power transmitter with the function of displaying one measuring value by installing the analog input module. It can be used as active/reactive power data collector with the function of displaying one measuring current by adopting RS-485 digital communication module, it can also be used for protecting over-limit alarm of normal active/reactive power by adopting the relay input module. Besides, by adopting all the three function modules, it can be a multi-functional network electric meter, which has measuring, alarming, transmitting, communicating, etc.

There are programmable keys on the panel, which can program and set parameters including transformer rate\upper and lower limit alarm value\communication address of the meter\communication baud rate\transmitting output method\transmitting output range, etc.
