Application
The energy-meters “with a white back-lighted LCD screen for prefect reading” are used to measure single-phase
like residential, utility and industrial application. The unit measures and displays various important electrical
parameters, and provide a communication port for remote reading and monitoring. Bi-directional energy
measurement makes the unit a good choice for solar PV energy metering.

Output
Pulse Output
The meter provides two pulse outputs. Both pulse outputs are passive type.
Pulse output 1 is configurable. The pulse output can be set to generate pulses to represent total / import/export
kWh or kVArh.
The pulse constant can be set to generate 1 pulse per: 0.001(default) /0.01/0.1/1kWh/kVArh.
Pulse width: 200/100/60ms
Pulse output 2 is non-configurable. It is fixed to import kWh. The constant is 1000imp/kWh.
RS485 output for Modbus RTU
The meter provides a RS485 port for remote communication. Modbus RTU is the protocol applied. For Modbus
RTU, the following RS485 communication parameters can be configured from the Set-up menu.
Baud rate: 1200, 2400, 4800, 9600 bps. Default: 2400bps
Parity: NONE/EVEN/ODD
Stop bits:1 or 2
Modbus Address: 1 to 247
Mechanics
Din rail dimensions 36x100x63 (WxHxD) DIN 43880
Mounting DIN rail 35mm
Ingress protection IP51 (indoor)
