333mV Flexible
Current Transformers
The Accuenergy Rogowski Integrator allows the convenience of a Rogowski coil to be used with any power meter or device with a 333mV nominal input. The RIK mV 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.

RIK 333mV Series Overview
What is an 333mV Integrator?
Integrators can amplify and transduce the standard output from the Rogowski coil to a commonly accepted signal, such 333mV. The integrator can also compensate for the Rogowski coil's inherent 90 degree phase shift. The 333mV output signal is a commonly used to monitor energy usage from a faciliity’s panel or through individual load circuits. 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

RIK 333mV Product Map
How it Works
If your third-party device does not include integrator circuitry, or you require a specific industrial output signal, select an Accuenergy RIK with an output option compatible with your device.
AcuCT Flex Rogowski Coils
The AcuCT Flex Rogowski coils are available in multiple lengths and flexible, rope-like form factor is ideal for measurement around irregularly shaped conductors or in crowded electrical panels. With a wide measurement range, Rogowski coils are the superior choice for demanding applications.
Accuenergy RIK mV
The Accuenergy RIK mV are designed to bridge the gap between AcuCT Flex Rogowski coils and devices without built-in integrator circuitry. Select from a number of industry-standard output signals and adapt to any installation with multiple, field-configurable ratio options.
Third-Party Devices without an Integrator
Add the convenience of AcuCT Flex Rogowski coils to any third-party device without a built-in integrator. The Accuenergy RIK mV connects devices such as such as a power meters, PLCs, RTUs, IEDs, or controllers to versatile Rogowski coils to overcome a range of installation challenges.
EMS Platforms, Gateways, or Servers
An effective energy management system, comprised of gateways, servers, and other hardware, relies on high-quality, reliable energy data provided by power meters and high-accuracy sensors, such as the AcuCT Flex Rogowski coils, for comprehensive energy management.
RIK mV Accessories
Rogowski Coils
RIK mV is compatible with Accuenergy's AcuCT Flex line of Rogowski coil sensors. Four standard lengths - 16", 24", 36", and 47", it can easily install into tight spaces. The non-invasive design is rated for high accuracy 0.5% measurements and a frequency response range of 10Hz-20kHz.
Power Supply
Accuenergy's PSU-240-24 power supply is compatible with RIK mV. With a DIN-rail mounting option, it can conveniently install in electrical panel enclosures. RIK mV uses 24Vdc power supply.
