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