MD-xHD Series Power Meters
Revenue-grade, Single- and Multi-Point Power Meters
Siemens Industry, Inc.
Description
Siemens MD-xHD series Power Meters are sub-metering
power and energy metering devices designed to provide real-
time, accurate electricity metering to enable proper control
over energy costs. The meters can capture kWh/kW energy
and demand data, as well as virtually all relevant energy
parameters for diagnostics and monitoring on three-phase or
single-phase circuit installations

Digital Energy Meters
A. Meter shall monitor voltage, current, power, energy, and many other electrical parameters on an electrical system,
including but not limited to:
• System and Phase measurements for: Amps, Volts, Frequency, kW, kWh, KVAR, kVARh, kVA, kVAh, dPF or
aPF.
• Net System true energy (kWh).
• System True Power +/- (kW).
• Meter shall be capable of measuring both positive and negative power to ascertain between power demand or
power generation for demand response, smart grid and on-site generation applications.
• System True Energy +/- (kWh).
• Meter shall be capable of measuring both positive and negative energy to ascertain between energy
consumption or energy generation for demand response, smart grid and on-site generation applications.
• Peak Demand (adjustable window and min/max system power).
B. Measured data updates shall occur every 1 second.
C. Meter shall be configurable for operation on Single Phase (AN or AB), Split Phase (ABN), Delta (ABC), and Wye
(ABCN) systems.
D. Meter shall be available with both Serial RS-485 or Ethernet interface.
E. Serial RS-485 communication shall support either user-selectable BACnet MS/TP or Modbus RTU protocol. Meter
shall be a BACnet Testing Labs (BTL) certified smart sensor (B-SS)
F. Ethernet communication shall support BACnet IP or Modbus TCP protocols in addition to the meter’s serial interface
supporting BACnet MS/TP or Modbus RTU protocols.
G. Meter shall have a multi-line backlit LCD displaying measured parameters.
H. Meter shall be Line-Powered from L1 Phase to L2 Phase. 80 to 600 Vac, CAT III, 50/60Hz, 70 mA max. No external
power supplies shall be required to power the meter.
I. Meter shall measure up to three voltage channels: 80 to 346 Vac Line to Neutral, 600 Vac Line-to-Line, or CAT III.
