*”xx” denotes length of current transformer coil

Directly compatible with select Accuenergy power and energy meters including Acuvim II and AcuRev 200

Directly Compatible with Acuvim Power Meters

Compatible with Acuvim II and AcuRev 2000 series power meters. Flexible CT connects directly into the energy meter just like a standard solid core or split core CT.

Model Range Calibrated To
RCTxx-1000 5 to 1200A
RCTxx-2500 12.5 to 3000A
RCTxx-5000 25 to 6000A
RCTxx-10000 50 to 12000A
RCTxx-50000 250 to 50000A
RCTxx-Custom Customize to different current sensing range when coil is directly connected to a meter.

*”xx” denotes length of current transformer coil

This table of current sensing range only applies when coil directly connect with our meters. Otherwise the sensing range is 5A to 50,000A

5A Rogowski Integrator Kit

5A-output integrator for flexible Rogowski current transformers, offers an easy-to-install, plug-n-play solution.


Highly Configurable Rogowski coil integrator for 5A systems

The Accuenergy Rogowski Integrator Kit (RIK) provides users with an easy-to-install, plug-n-play solution to be used with any power meters or equipment with a 5A current transformer input.

  • Flexible rope-like current sensor, designed to easily fit into panels or busbars where space may be limited
  • 0-5A rated output that works with any power meter or equipment with 5A nominal current transformer input
  • Current sensing range from 2.5A to 50,000A to fit all systems
  • Seven field-configurable CT ratios: 500A, 1kA, 2.5kA, 5kA, 10kA, 25kA, 50kA
  • Individual CT ratios can be configured for each channel. Works in any single phase application with different current ratings
  • Works in both 50Hz and 60Hz systems
