APPLICATION
The energy-meters are used to measure single-phase applications like residential, utility and Industrial. The unit measures and displays various important electrical parameters.
It is equipped with a white back-lighted LCD screen for perfect reading. As well as an RS485 communication port for remote reading and monitoring. Bi-directional energy measurement makes it a good choice for solar PV energy metering. The compact design and din rail installation provide an easy and economical solution for your metering demand.
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: 0.001/0.01/0.1/1 kWh/kVArh.
Pulse width: 200/100/60ms
Pulse output 2 is non-configurable. It is fixed to total kWh. The constant is 1000imp/kWh.
RS485 output for Modbus RTU
The meter provides an RS485 port for remote communication. Modbus RTU is the protocol applied. For Modbus RTU, the following RS485 communication parameters can be configured by the Modbus command.
Baud rate: 1200, 2400, 4800, 9600 bps. Default: 2400 bps
Parity: NONE/EVEN/ODD
Stop bits: 1 or 2
Modbus Address: 1 to 247
