EM3500 series

Compact, affordable series of DIN mounted meters

DIN rail energy meters for monitoring in building automation systems

EM3500 series
  • Features

    The PowerLogic EM3500 series energy meters combine exceptional performance and easy installation to deliver cost-effective power monitoring applications to your customers. The DIN rail-mounted meters can be surface mounted as needed.

    The PowerLogic EM3500 series meters come in four models.


    • Pulse outputs for real and reactive energy consumption
    • Real-time alarm output
    • All other measurements available on backlit LCD display


    • 2-wire RS-485 serial communication with Modbus RTU protocol
    • Pulse outputs for real energy consumption and real-time alarms
    • 2 quadrant metering


    • 2-wire RS-485 serial communication with Modbus RTU protocol
    • Pulse outputs for real energy consumption and real-time alarms
    • 4 quadrant metering
    • Logging capacity


    • 2-wire RS-485 serial comm with BACnet MS/TP protocol
    • Pulse inputs to accommodate sensors measuring other forms of energy
    • 2 quadrant metering
    • Logging capacity

    Common characteristics

    • ANSI C12.20 class 0.5% and IEC 62053-22 Class 0.5S for active energy
    • Class 2% for reactive energy
    • Supports single phase, split-phase, or 3-phase circuit configuration (delta or wye)
    • Backlit LCD display
    • All Models provide a full range of data measurements
    • Uses low-voltage CTs (1V or 1/3V)
    • External control power supply (90-600 V) for maximum flexibility
    • Operating Temperature -30°C to 70°C


    Low voltage current transformer (LVCT) connections are more compact and provide lower installation costs and a safer environment.

    Native building automation protocols (BACnet or LONworks) allows for direct integration into building management system (BMS) software.

    600 V direct connections for measurement inputs and control power reduce the need for potential transformers, which saves space and installation costs.


    Energy efficiency and cost control applications (cost management)

    • Bill verification
    • Tenant metering (commercial sub metering)
    • Cost allocation
    • Green technologies monitoring (Renewables)

    Power availability and reliability applications (network management)

    • Power metering
    • Basic network monitoring
