Press Release: E-Mon Releases New Smart Meters with Dual Protocol Capabilities

E-Mon's new Smart Meters for Energy/Power Quality and BAS Integration earn UL/CUL/ANSI Listings. New meters extend feature set, offer wider range of metering functions from basic to dual protocol, load control, net metering ,expanded memory and storage, and more!

LANGHORNE, PA — December 1, 2011 — E-Mon, the electric submetering market leader and manufacturer of the widely installed E-Mon D-Mon product line, announces the availability of four new Smart Meter Class devices. E-Mon's new smart meters offer built-in communication, advanced energy information-including 38 metering parameters-and expanded communication functions. In addition to recently completing requirements for UL/CUL listing, the meters were certified by an independent testing lab as meeting ANSI C12.20 national accuracy standards of +/- 0.2% from 1-100% of rated load.

Three of the meters, Class 3400, 5000 and Green Class Net Meter offer simultaneous dual-protocol communications for integration with multiple BAS systems, billing packages or M&V reporting. "This capability enables one meter to talk to two systems at the same time over industry-standard protocols," said Don Millstein, President & CEO. "This greatly enhances the value of any meter investment by allowing the user to obtain granular meter data from a single device acting as a separate billing meter and also an independent building automation system meter."

To further facilitate cost-effective operation, the meters offer reduced-cost BAS protocol options. The individual features of each new meter include:

Class 3200 - Available now in a Multiple Meter Unit (MMU) version, the Class 3200 offers a 4-line LCD display showing kWh; demand with peak date and time; power factor (%) per phase, real-time load in kW, Amps per phase and more. Meters include built-in RS-485 communications and come standard with EZ7 protocol for use with E-Mon Energy software in NEMA 4X enclosures for booth indoor and outdoor use. Class 3200 meters are optionally available with Modbus RTU and BACnet MS/TP protocols.

Class 5000 - Offers everything the Class 3200 does, including dual-protocol functionality, Ethernet and more in a standalone, non-MMU configuration. The dual-protocol output allows operation for RS-485 and Ethernet communication simultaneously, along with independent communication with E-Mon's Automatic Meter Reading (AMR) system and Building Automation System (BAS) or other front-end monitoring system. Communication media choices include Modbus RTU, Modbus TCP/IP, BACnet MS/TP, BACnet IP or Lonworks (TP). Also provided are two external inputs for gas, water, BTU or other pulse-output meters and a phase-loss alarm.

Class 3400 - Provides everything the Class 5000 does, but comes in a larger 6" x 8" enclosure equipped with a larger 4-line LCD display and is available with an optional expanded feature package that includes built-in functions for load control and two pulse outputs (one kWh and one kVARh).

Green Class Net Meter - Designed for applications requiring collection of net data, this meter provides the same feature set as the Class 5000 but adds kWh delivered, received and net kWh. It also includes dual protocol functionality, Ethernet, pulse inputs and phase-loss alarming in a stand alone, non-MMU configuration.

The new meters provide revenue-grade accuracy and operation with 3-phase, 3-wire (delta) and 3-phase, 4-wire (wye) circuits. Models are available for 208, 480 and 600V applications with split-core current sensors from 100 amp to 3200 amp. Each meter class provides an MV-90 compatible configuration.

"The wide range of functionality offered by these meters allows users to select the model and feature set that best fits their needs, without paying for bells and whistles they may not need," Millstein noted.
