Application

This document provides operating, maintenance and installation instructions.
The unit measures and displays the characteristics of single phase two wire(1p2w) supplies, including voltage, frequency, current, power, actve and reactive energy, bi-directional energy measurement, etc. which makes it a good choice for solar PV energy metering, residential, utility and industrial application.
The unit equipped with a white back-lighted LCD screen for prefect reading. Built-in interfaces provides RS485 Modbus RTU outputs and pulse output. Digital input is provided for external signal counting. Configuration is password protected.

Output
RS485 output for Modbus RTU (For RS485 Modbus meters only)
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, 9600,19200 bps. Default: 2400bps
Parity: NONE/EVEN/ODD. Default: NONE
Stop bits:1 or 2
Modbus Address: 1 to 247

Mbus Port (For SDM230-Mbus only)
The meter rovides a Mbus port for remote communication. The meter adopts EN13757-3 Mbus communication protocol. The communication parameters can be configured via the SET-UP mode.
Baud rate: 300, 600, 1200, 2400, 4800, 9600 bps
Parity: NONE/ EVEN/ODD
Stop bit: 1 or 2
Primary address: 001-250
Secondary address: 00000001~99999999

Pulse Output (Not avaiable for SDM230M-DI)
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.

2T for dual source measurement (For SDM230-2T only)
This unit can measure energy from two different power supplies. For example, when public grid is power off and el ectric generator is on, the meter switches to tariff 2 measurement automatically.
The meter can also be used as a tariff meter. The tariff is controlled by an external time relay.

• During normal operation, voltages hazardous to life may be present at some of the terminals of this unit. Installation and servicing should be performed only by qualified, properly trained personnel abiding by local regulations. Ensure all supplies are de-energized before attempting connection or other procedures.
• Terminals should not be user accessible after installation and external installation provisions must be sufficient to prevent hazards under fault conditions.
• This unit is not intended to function as part of a system providing the sole means of fault protection good engineering practice dictates that any critical function be protected by at least two independent and diverse means.
• If this equipment is used in a manner not specified by the manufacturer, protection provided by the equipment may be impaired.
