PWR METER BMED W-QTY3 400A REV-GRADE CT

Siemens MD-BMED 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. These “revenuegrade” meters 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.

Description

Siemens Industry's MD-BMS and MD-BMED Model Power Meters are submetering devices designed to provide real time, accurate electricity metering to enable proper control over energy costs. The meter can capture kWh/kW energy and demand data, as well as virtually all relevant energy parameters for diagnostics and monitoring on three-phase or singlephase circuit installations. The meters’ flexibility, size, and ease-of-use make them ideal tools for gathering detailed consumption information in commercial, industrial, governmental, and retail environments. The meters use direct connections to each phase of the voltage and various interchangeable current transformer (CT) options such as split-core CTs or flexible Rogowski Coils (for large loads or large cables and bussbars) to monitor current on each phase. All of Siemens' current transformers are internally shunted for intrinsically safe operation on energized conductors. The power meters make over 75 total electrical measurements which are derived from the voltage and current inputs. Electrical load diagnostic parameters such as power factor and line frequency are captured in addition to energy and demand values. The Siemens MD-BMS and MD-BMED Power Meters require no external power and the power supplies can accommodate service voltages ranging from 80 to 600V (phase-to-phase). The simple installation is accomplished by connecting the color-coded voltage leads and clearly labeled CTs. A three-LED indicator display confirms proper CT-to-phase installation. The meters automatically adjust for CT orientation—greatly reducing set-up time and all but eliminating installation errors. The display model (MD-BMED), features an integrated 2 × 16-character backlit display which cycles through key configuration data along with voltage, current, power, and power factor, by phases

Features

(Continued) Siemens MD-BMS and MD-BMED Model Power Meters use interchangeable CT options such as splitcore or flexible Rogowski-style CTs. The meters have embedded Rogowski Coil CT amplifier/integrator circuitry, so there is no need to provide external power to the CTs.

Communications interface to the meters is through an RS-485 serial connection using BACnet MS/TP (default) or Modbus RTU protocol. Advanced configuration can be completed by using ViewPoint™ software.

The MD-BMED has an integrated Ethernet port which supports BACnet IP or Modbus TCP in addition to the RS-485 communication options noted above. This model also provides a new backlit display.
