Typical applications

The following table presents some of the functions of the different meters, the advantages and main applications.

Functions

Advantages

Applications

Meter

Total and partial energy counters

Energy usage monitoring

Sub-billing management

Metering applications

iEM3400 / iEM3500 series

Internal clock

Saves the date and time of last reset

Provides the timestamp of the last reset of the partial energy accumulation

iEM3400 / iEM3500 series

Manages up to four tariffs, controlled by the digital input(s), internal clock or communications (depending on meter model)

Categorize energy consumption into On Peak and Off Peak, working days and weekends, or by different electricity sources (for example, from the utility and an electrical generator)

Energy demand management

Sub-billing management

Identification of local energy consumption behavior by zone, by usage or by feeder

iEM3400 / iEM3500 series

Measures essential electrical parameters like current, average voltage and total power

Instantaneous measurements help you monitor the imbalance between phases

Total power allows you to monitor the feeder load level

Monitoring of feeders or any sub-cabinet

iEM3400 / iEM3500 series

Modbus communications

Communicate advanced parameters using Modbus protocol

Modbus network integration

iEM3455 / iEM3555

BACnet communications

Communicate advanced parameters using BACnet MS/TP protocol

BACnet network integration

iEM3465 / iEM3565

Four quadrant calculation

Identification of imported and exported active and reactive energy allows you to monitor energy flow in both directions: delivered from the utility and produced on-site

Ideal for facilities with back-up generators or green power capabilities (for example, solar panels or wind turbines)

iEM3400 / iEM3500 series

Measurement of active and reactive energy

Allows you to monitor energy consumption and production

Manage energy consumption and make informed investment to reduce your energy bill or penalties (for example, installing capacitor banks)

Programmable digital input

Can be programmed to:

  • Count pulses from other meters (gas, water, etc.)

  • Monitor an external status

  • Reset the partial energy accumulation and start a new period of accumulation

This allows for monitoring of:

  • WAGES

  • Intrusion (for example, doors opening) or equipment status

  • Energy usage

Programmable digital output

Can be programmed to:

  • Be an active energy (kWh) pulse output, with a configurable pulse weight

  • Alarm on a power overload at a configurable pickup setpoint

This allows you to:

  • Collect pulses from the meter with a Smartlink system, PLC or any basic acquisition system

  • Monitor power levels at a detailed level and to help detect an overload before the circuit breaker trips
