Jan 01, 0001

The specifications below are designed to be cut and pasted into your engineering/ordering documents for easy specification of E-Mon D-Mon Class 3400 meters.

  • Meter shall be fully electronic with 4-line x 20-character backlit LCD display showing kWh, kW demand (with peak date and time), power factor per phase, real-time load in kW, Amps per phase and Volts per phase.
  • Meter shall use 0-2 volt output current sensors to allow paralleling and/or mounting up to 500 feet from the meter. Sensors shall be of split-core configuration to allow installation without disconnecting cabling, etc. Split-core sensors shall be available from 100 amp to 3200 amp. Sensors shall be optionally available in solid-core configuration (100 & 200 amp.)
  • Meter shall be field programmable for meter date/time, IP address and ID code for communication option and optional load control settings.
  • Meter shall provide installation diagnostics on display.
  • Meter shall be enclosed in a NEMA 4X polycarbonate enclosure (standard) with padlocking hasp & mounting flanges for indoor/outdoor installation (stand alone) with one 1 1/16" KO on bottom of enclosure. Optional heavy duty JIC steel enclosure available for indoor installation.
  • Meter shall be UL Listed/CUL Listed to latest applicable standards for safety.
  • Meter shall meet or exceed ANSI C12.20 accuracy standards.
  • Meter shall meet or exceed MID accuracy standards.
  • Meter shall provide non-volatile memory to maintain reading during power outages.
  • Meter shall store interval data for kW and kVAR for up to 72 days in first-in first-out format. (Standard firmware.) Interval data not available via BACnet or LonWorks.
  • Meter shall be optionally available in single-phase, 3-wire configuration.
  • Meter shall provide optional 5th & 6th channel for logging inputs from third-party metering devices (gas, water, BTU, etc.) Both channels provide interval data logging that can be read via E-Mon Energy software and Modbus.
  • Meter shall be capable of daisy-chain connection using RS-485 communications in combinations of Din-Mon D2 & D5, Class 3200s, 3400s, 5000s, IDR-8s, IDR-16s not to exceed 52 devices. Cabling shall be available through terminal block (3-conductor), 18-22 AWG, up to 4,000 cable feet total.
  • Meter shall be available with the following communication protocol & option packages:
RS-485 Port Ethernet Port Specify
EZ7 EZ7 Ethernet 01
Modbus RTU EZ7 Ethernet 02
BACnet MS/TP EZ7 Ethernet 03
EZ7 Modbus TCP/IP 04
