Meter

Introduction

• The SDM230 series, manufactured by Eastron Electronic Co., Ltd., measures and displays the characteristics of a single-phase two-wire (1p2w) network. The series includes five models:
  • SDM230-Modbus
  • SDM230-Pulse
  • SDM230Mbus
  • SDM230-2T
  • SDM230M-DI
• The bi-directional measurement makes the meter suitable for import and export energy and power monitoring applications, and also perfect for solar PV measurements. With RS485 Modbus and M-bus ports, the meter is easy to remotely communicate with other AMR/SCADA systems.

Key Characteristics

• The SDM230 series measures:
  • Voltage (U)
  • Current (I)
  • Active power (P)
  • Reactive power (Q)
  • Apparent power (S)
  • Power factor (PF)
  • Frequency (Hz)
  • Demand (Dmd)
  • Energy (kWh)
  • Reactive energy (kVArh)

  • Export energy
• The SDM230 series also includes:
  • RS485 Modbus communication
  • Pulse outputs (configurable and non-configurable)
  • Multi-tariffs (SDM230-2T only)
  • Dual-source measurement (SDM230-Pulse only)

Pulse Output

The meter provides two pulse outputs. Both pulse outputs are passive type. Pulse output 1 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: 0.001/0.01/0.1/1kWh/kVArh (default is 0.001 export kWh). Pulse width: 200/100/60ms Pulse output 2 is non-configurable. It is fixed with active kWh (Imp). The constant is 1000imp/kWh.

Communication

The SDM230 series includes RS485 Modbus communication and M-bus communication (SDM230-Mbus only). Both ports provide a means of remotely monitoring and controlling the unit. Set-up screens are provided for setting up the RS485 port and M-bus port.

Usage Instructions

Before using the SDM230 series, please read the safety instructions provided in the user manual carefully.
To use the SDM230 series:

1. Install the meter according to the installation instructions provided in the user manual.
2. Connect the meter to the power supply.
3. Configure the pulse outputs (if applicable) and communication ports using the set-up screens provided in the user manual.
4. Use the RS485 Modbus or M-bus protocol to remotely monitor and control the unit.
   Note that the SDM230-Pulse model can measure energy from two different power supplies. For example, when the public grid is powered off and an electric generator is on, the meter switches to tariff 2 measurement automatically.

Safety Instruction

• The Installation instructions do not include a complete list of all safety measures necessary for operating the device. Special operating conditions may require additional measures. The installation instructions contain notes that must be observed for your personal safety to prevent property damage.
• Safety instructions in this document are highlighted with a warning triangle and are presented as follows depending on the level of risk.
• The General warning symbol calls attention to possible risks of injury. Observe all the instructions listed under the symbol to prevent injuries or even death
• This additional symbol indicates any electrical danger that can result in serious injuries or death
  Attention
  Warns of an imminently dangerous situation that can result in property damage or environmental damage in the event of noncompliance.
