4-20mA / 0-20mA Output Flexible Current SensorRIK 4-20mA / 0-20mA Rogowski Integrator Kit

The Accuenergy mA 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 mA nominal current transformer input. The mA Rogowski Integrator will allow the installation of Rogowski coil CTs in a variety of applications where space constraints may limit the use of other current transformers

The 4-20mA flexible coil integrator kit is designed with three independent channels of 4-20mA or 0-20mA output, plus a sum output channel and Accuenergy flexible Rogowski coil current sensor.

Included in the kit are one or three Rogowski coils customized for each order.

Rogowski Coil Benefits

Rogowski Coils are high-specification flexible current transformers that are ideal for use when space is limited. The flexible form factor of a Rogowski Coil means they easily fit into tight panels and come in a range of sizes to suit most installations.

Like standard split core transformers, Rogowski coils can be easily integrated into existing panels without having to cut any lines.

Items Included In The Kit

Each Rogowski Integrator Kit includes:

  • Single or three channel integrator
  • Three AcuCT Flex current sensors
  • Available in an array of sizes from 16” to 47”.
  • 100-240Vac Din-rail mount power supply
  • Choice of DIN rail or surface mount
  • Each part is highly configurable to the appropriate application.
