Product Description

 

DC Multi-function Energy Meter PZ72L-DE

Product Description

 

PZ series intelligent DC energy meter is designed for applications such as DC panels, solar power, telecommunications base stations, and charging posts. This series of instruments can measure voltage, current, power, and forward and reverse power in a DC system. It can be used for local display and connected with industrial control equipment, and computers, to form a measurement and control system. And it has a variety of external excuse functions for the user to choose: from RS485 communication interface, Modbus-RTU protocol, relay alarm output, and digital input/output. According to different requirements, through the instrument panel keys, you can set the ratio, and communication parameters. The product meets the relevant technical requirements of the standard Q/GDW1825-2013 DC power meter specification, GB/T29318-2012 Non-vehicle charging electric energy metering for electric vehicles, Q/GDW364-2009 Single-phase energy meter specification.
