Model:EC-3A

Description

The EC-3A is used to determine feeder loading and is mainly used by power distribution companies, heavy industry, facilities management, electrical or site services and maintenance engineers to monitor loading variations on site helping them to diagnose any related issues, transformer and feeder sizing problems. The EC3A is perfect for gathering data to make a case for splitting-up the loading or increasing circuit capacity.

The EC-3A-xK models are designed for large loads up to 3kA versions. If you require higher inputs still then currents up to 10kA are possible. Please contact us regarding these.

The Rogowski Coils fit around cables of 140mm diameter or less.

The EC3A-xK uses USB communications.

2014: Now available as -RS version, with selectable ranges: 4A to 400A or 20A to 3kA.

For lower currents, we recommend the CT-3A-RS (ex EC-3CT) which uses traditional clamp-on current transformers (CT's) and has selectable input ranges of 0.5 to 60A or 4A to 400A, making it accurate at lower currents, suitable for domestic and light commercial logging.

Features

  • Rogowski fits round 140mm diameter cables. 
  • Complete with Coils USB lead carry case & software.
  • Records true RMS Iavg, Imax & Imin to 5%.
  • 10 bit resolution.
  • USB Comms
  • Free software included.
  • Prints dispatch & return documentation.
  • Allows rapid response to issues.
  • Sealed to IP65 or NEMA 12/4.

Specifications

  • Recorded Values: Iavg,  Imax,Imin on all 3 channels
  • Current Input socket types (all channels): Hard-wired through cable glands
  • Imax & Imin Time resolution: Always one cycle (50/60Hz), independent of averaging period
  • Supplied Current Sensor Accuracy: +/-2% of range
  • Current Measurement Range (Irms):
    4A to 400A or 20A to 3kA
  • Sampling frequency (all channels): 16 samples per cycle 800Hz @ 50Hz
  • Data recorded: Average, Max. and Min. values during the averaging period
  • Memory Capacity: 192kB, able to record up to 32,000 levels per channel/phase
  • Memory type: non-volatile SEEPROM
  • Memory averaging period and duration: 1sec- 60 mins (1sec average gives 2 hours of logging, 60min average gives 300 days)
  • Real-time clock accuracy: greater than 0.001%
  • Input lead length: 1.3m
  • Battery life while logging: Unlimited - 12Vdc PSU option + battery backup or 3 months while unpowered
  • Battery type: unit contains fourteen 9V Alkaline battery (PP3 type) or External PSU
  • Communications interface type: USB, baud of 19200, optically isolated to 5.2kV
  • Environmental: -10°C to +40°C, IP65
  • Dimensions and Weight: 250 x 175 x 70mm @ 1Kg
  • Standards: Recording - EN50160: 1994 - Cat III
