Meter Options

Pulse Output (Suffix Q)
Load Control Option (Suffix LC)


Communication Options

Requires E-Mon Energy software
for reading:
Telephone Modem (Suffix M)
Ethernet Communication (Suffix E)

Requires third-party EMS/BMS system supplied by others. E-Mon Energy not used:

Pulse Output (Suffix Q)
Modbus RTU (Suffix RTU)
** Modbus TCP/IP (Suffix ERTU)
**BACnet IP (Suffix EB)
LONworks TP (Suffix LTP)

** Modbus TCP/IP and BACnet IP communicates over Ethernet. No RS-485 daisy-chain capabilities with Modbus TCP/IP and BACnet IP. Each meter must connect directly to the BACnet/Modbus backbone and have a unique IP address.


Class 3000 Advanced Submeter with Communications


  • • Easy to read cycling 4-line by 20 character backlit LCD display:
    0000- kWh
    0000- kWh/Demand (with peak date and time)
    • 0000- Power factor per Phase
      • 0000- Real-time load in kW
      • 0000- Amps per Phase
      • 0000- Volts per Phase
      • 0000

• Patented 0-2 volt output split-core current sensors promote enhanced safety and accurate remote mounting of current sensors up to 500 feet from the meter without power interruption. (Optional solid-core current sensors available in 100 & 200 Amp.)
