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.

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.
