E-Mon’s Smart Meters for energy / power quality and BAS integration offer dual-protocol operation, load control, net metering, expanded memory and more. All series devices provide revenue-grade accuracy for 3-phase, 3-wire (delta) and 3-phase, 4-wire (wye) circuits. The series’ wide range of functionality lets users select the ideal feature set for their energy monitoring needs, without paying for unnecessary functions.
Three of the meters — the 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 and 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 as an independent building automation system meter.”
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 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 both 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 communications simultaneously, along with independent communication with E-Mon’s Automated Meter Reading (AMR) systems and the 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 Lon-Works (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 standalone, non-MMU configuration.
