0-5V / 0-10V Output Flexible
Current Sensor

The Accuenergy Rogowski Integrator allows the convenience of a Rogowski coil to be used with any power meter or device with a 0-5Vdc or 0-10Vdc nominal input. The RIK V integrator facilitates the installation process of Rogowski coil CTs for a variety of applications where the spatial constraint may limit more rigid-style current transformer formats. The seven user-selectable input ranges ensure the Rogowski Integrator can be compatible with any system up to 60,000A AC. Available as either a three phase or single phase instrument, each integrator support the use of the AcuCT Flex Rogowski coils or 24Vdc power supply.

*Rogowski coil and power supply are sold separately.

  • Field-selectable 0-5Vdc or 0-10Vdc rated output works with any power meter or device with a V nominal current transformer input.
  • Integrator includes a fourth sum channel to output total current from the three other channels (three-phase kit only)
  • Flexible, rope-like current sensor, designed to easily fit into crowded electrical panels or around busbars*
  • Current sensing range from 2.5A to 50,000A for compatibility across any system.
  • 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.
  • Compatible with both 50Hz and 60Hz systems"

*Rogowski coil and power supply are sold separately.

RIK V Series Overview

What is an 0-5V / 0-10V Integrator?

Integrators can transduce the standard output from the Rogowski coil to a commonly accepted 0-5V or 0-10V signal. The integrator can also compensate for the Rogowski coil's inherent 90 degree phase shift. The 0-5Vand 0-10V output signal is a commonly used in flow or pressure applications such as lighting, water management and hydraulic systems. It provides an easy-to-use solution for 3rd party power meters or other equipment.

Rogowski Coil Benefits

Rogowski Coil current transformers are designed for precision AC current measurement in power metering or general energy monitoring applications. Flexible Rogowski coils provide a versatile solution in crowded electrical panels where rigid-body current transformers simply will not fit. Much like a split core current transformer, the user-friendly locking connector opens for easy integration into existing panels without disconnecting wires. Available in four sizes to suit any application.

Included in Kit

Rogowski Integrator includes:

  • A three channel integrator

Compatible Accessories (Each sold separately):

  • Three AcuCT Flex current sensors in one of four available sizes
  • 100-240Vac DIN-rail mount power supply
