Meter with inside relay support for connect and disconnect functions.
2. Features and Technical Parameters
2.1 Features
●LCD display show voltage, current, power, and kWh.
●Measuring total energy consumption, support both active and reactive energy measurement.
●Meter with inside relay 80A which support on and off function through communication program
●Meter support both RF and RS485 communication, protocol for RS485 is DTL645, protocol for
RF is self defined.
RS485 communication: baud rate 9600 (fixed), eight data bits, even parity check, one stop bit
