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) |
