MD-12HD Networked Multi-Circuit

Power Metering System, 12-Channel

Description

MAXIMUM FLEXIBILITY FOR MONITORING

The MD-12HD is a versatile, multi-channel electrical

metering instrument, used for monitoring up to twelve

electrical circuits. It uses any of the existing MD series

internally-shunted, 333 mV output split-core or

Rogowski Coil current transformers (CTs). Monitor any

combination of up to 4 three-phase or 12 single-phase

electrical devices with a single meter. With over 100

data registers, data updates every second and ANSI

C12.20-2010 Class 0.2 revenue grade accuracy, the

MD-12HD is well-suited for data center monitoring,

tenant submetering, and accountability metering in

commercial, retail, and industrial facilities.

INDUSTRY-STANDARD BACNET OR MODBUS

The MD-12HD supports both BACnet protocol and

Modbus protocol (based on SunSpec IEEE-754

floating point model). Communications interface can

be accomplished through standard serial RS-485 or

Ethernet using either BACnet MS/TP, Modbus RTU,

BACnet IP or Modbus TCP protocols. Additionally, the

MD-12HD features four pulse inputs.

EASY INSTALLATION

This meter is line-powered and designed to operate on

any voltage from 90 to 600 Vac. BACnet and Modbus

protocols are field-selectable and any combination of

split-core or flexible Rogowski Coil (RōCoil™) CTs can

be used. Configure the meter prior to installation using

the free ViewPoint™ HD software utility and a direct

USB connection or by using the built-in web server.

PhaseChek™ technology ensures proper CT-to-phase

installation the first time, eliminating installation errors.
