General
This multifunction power meter is featured by small size, high
accuracy and easy installation. It has functions including all
electrical quantities measurement, electric energy calculation and
management, single channel residual current measurement, and total
harmonics (within 21 times) measurement. Remote communication and
remote control functions can be realized due to the design of
digital input and relay output. This energy meter is equipped with
RS485 communication interface and configurable with Modbus RTU
protocol, it is widely applied in a variety of control systems,
SCADA systems and energy management systems. Technical parameter
