Product Overview

Siemens MD-BMS-3-CTSC-100A, BACnet-Modbus Meter with three 100A, split-core current transformers with 1 Windows
p>Siemens MD-BMS Power Meters are BACnet-Modbus metering devices designed to provide real time, accurate electricity metering to enable monitoring and control over energy costs. They are compatible with most BMS systems. This revenue grade meter can capture kWh/kW energy and demand data, as well as other relevant energy parameters for high accuracy applications such as demand response or tenant submetering.


  • Works on Sigle or 3-Phase Power Services
  • Mounts inside electrical cabinet - no separate enclosure required.
  • Uses BACnet or Modbus protocols for easy interface to most BMS
  • LEDs indicate and ensure correct CT phase orientation
  • Data updates occur every 0.5 sec
  • Standard Pulse Output
  • Line-Powered: 60-600V Phase-Phase Power Supply. Use on 12024, 20/120, 4/277V or 580335V, 38022 services; 50or 60 Hz

Unique Sellig Points

  • Both models compatible with most BMS systems, communicatig via RS-4sig BACnet MS/TP or Modbus RTU protocols.
  • Measures over 75lectrical, power and enegy parameters.
  • ANSI C12.20200 class 0.2 revenuegrade meter performance;good for submeterig.
  • Kits provide meter plus three CTs with rages from 100 Amps to 40 Amp. Kits are pre-confgured in factory to minimize need for field confguration and setup.
  • New 5 year warranty!
