MD-3HD Networked Power Meters
Features
• Standalone sub meters with various
communication options including:
MS/TP, Modbus RTU, Modbus TCP
and BACnet IP
• MD-3HD-R-D-N for DIN Rail mount
• MD-3HD-C-D-N for wall mount
• Order CTs separately.
These highly accurate ANSI C12.20-2010
Class 0.2 meters provide real time
electricity metering data to any building automation system to support
control of building or equipment energy costs. They capture kWh/kW
energy and demand data in addition to over 90 other electrical
parameters for three-phase or single-phase electrical services.
No current transformers are included with these individual meters.
These sub meters can be configured to utilize a wide range of MD series
CTs via the meter USB port; using the free ViewPoint HD software.
Applications
These meters can be configured to utilize any MD series CTs to create
job-specific current metering ranges. They can also be replacements.

MD-12HD Series
High Density Networked Metering System
Features
• 12-channel networked power metering
device with optional display, enclosure.
• Supports BACnet MS/TP, IP; Modbus RTU,
TCP per SunSpec IEEE-754 floating point.
• Includes four pulse inputs, power/current
alarms and internal logging of kWh data.
• ANSI C12.20-2010 Class 0.2 Revenue Grade
meter for voltages from 90 to 600 Vac.
• Metering targeted for single- and three-phase circuit
measurements.
This 12-channel networked metering system provides real time
electricity metering data to any building automation system to support
control of building or equipment energy costs. They capture kWh/kW
energy and demand data in addition to hundreds of other electrical
parameters for three-phase or single-phase electrical services.
No CTs are included with these metering systems. These high-density
meters can be configured to utilize any of the MD series CTs via the
meter’s USB connection; using the free ViewPoint-HD software.
Applications
This high-density networked meter’s flexibility, size, and ease-of-use
make it ideal for gathering detailed consumption information for retail,
commercial, data center, educational, government and industrial uses.

MD-3HD-R-D-N Installation Accessories
Features
• Accessories to promote proper
installation and safety practices
• Meter mount and fuse protection
module provides increased safety.
• Small meter enclosures provide
NEMA1 housing for two meters.
• Optimized for use with MD-BMS
and MD-BMED metering systems.
The model #567-090 DIN rail mount and fuse module provides easy
meter mounting and meter external fusing for up to 600 Vac. Fuse
blocks are clearly labeled for phase connections and convenient wires
provide quick connection to the MD series meters.
NEMA 1 rated cabinets, with UL and CSA listings, are available in sizes
optimized for the MD series meters. See models #567-551 for a blank
door and #567-556 for a windowed door for observing the display.
Applications
For sub meter interior mounting and fusing in locations near the
equipment being measured.
