RIK 5A Overview

Highly Configurable Rogowski coil current transformer integrator for 5A systems.

The Rogowski Integrator Kit is ideal for projects that face spatial constraints yet still need a 5A output for their device or power meter. Rogowski Coils are high-specification current transformers that are flexible enough to fit into tight spaces where other form factors like a solid core CT or split core CT will not. The RIK can be used in both 50Hz and 60Hz systems with a rated frequency range of 45Hz to 65Hz.

How Rogowski Integrator Kit Works

A Rogowski coil will sense the current flow through a conductor and deliver it to the RIK. The Integrator can sense one of seven selected input ranges (500A, 1kA, 2.5kA, 5kA, 10kA, 25kA or 50kA with sensing range of 0.5% to 120% of rated current input) configurable by the user. The RIK has three 5A output channels that sends the signal to the connected equipment with a 5A input such as the Acuvim II series power meter.

RIK 5A Additional Details

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:

  • Integrator unit
  • Three AcuCT Flex current sensors
  • Available in an array of sizes from 16” to 47”.
  • 24Vdc power supply
  • Choice of DIN rail or surface mount
  • Each part is highly configurable to the appropriate application.
