The ION 7550-ION 7650

ION7550/ION7650 Meters provide high performance in HV or LV installations.
Designed for main circuits or critical loads.

Energy usage and power quality meter for industrial or utility network installations.

The ION7550 and ION7650 each have a different feature set:

  • ION7550: revenue-class power and energy metering, event and min/max logging, historical logging (up to 800 channels), expandable memory, sag/swell monitoring, harmonics measurement, waveform capture at 256 samples/cycle, setpoints, digital and analogue I/O, and Internet-enabled multi-port Cat5 of fiber communications
  • ION7650: provides symmetrical components measurement, fast transient detection, waveform capture at 1024 samples/cycle, and power quality compliance monitoring.

Characteristics (some features are optional):

  • Panel-mount, large customizable LCD display (also available without display)
  • Multilingual support for English, French, Spanish and Russian. User-configurable IEC or IEEE notations. 12/24 hour clock support in multiple date/time formats.
  • 3-phase, 4-quadrant metering, class 0.2 accuracy (IEC, ANSI)
  • Voltage, current, neutral and earth current, power, frequency, power factor, demand, energy, and time-of-use metering
  • Instrument transformer correction, transformer/line loss compensation
  • IEC 61000-4-30 class A ed. 2, IEEE 519/1159, EN50160, IEC 61000-4-7/4-15 power quality compliance monitoring
  • 1024 samples/cycle waveform capture, transient capture (20 μs @ 50 Hz), sag/swell monitoring, harmonics measurement (up to 63rd), symmetrical components
  • COMTRADE waveform format available directly from the meter
  • Disturbance direction detection to indicate whether a disturbance originated upstream or downstream from the meter
  • Setpoint learning to automatically learn what constitutes a sag, swell, transient or high and low setpoint
  • Sequence-of-events, coincident minimum/maximum, historical trends, and high-speed snapshot recording, 1 ms resolution timestamping, GPS time synchronisation
  • 4 analogue inputs, 4 analogue outputs, 16 digital status/counter inputs, 7 digital control/pulse outputs
  • 65 setpoints for alarms and control, 1/2 cycle response, multi-condition, call out on alarm
  • 5 communication ports: Ethernet, modem, RS-232/485, RS-485, front panel optical
  • 100Base–TX and 100Base–FX for faster Ethernet communication
  • Protocols: Modbus RTU slave/master, Modbus TCP, DNP 3.0, MV-90, IEC 61850
  • Ethernet and modem gateways to 31 devices on RS-485 port
  • On-board web server, email for alarms and data, FTP server
