SDM230-Modbus 100A Multifunction Energy Meter With RS485 Port Single phase Meter
Description:
The energy-meters “with a blue 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.
Features:
- Measures kWh, Kvarh, KW, Kvar, KVA, PF, Hz, dmd, V, A, etc.
- Bi-directional measurement IMP & EXP
- Two pulse outputs
- RS485 Modbus
- Din rail mounting 35mm
- 100A direct connection
- Better than Class 1 / B accuracy

| 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 up with 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
Parity: NONE/EVEN/ODD
