3 Phase Flexible Transformer RCS-2400 by Magnelab


All RCS units require Active Power

Product Description

Magnelab’s RCS-2400 is a 3 Phase Flexible Transformer kit that transforms an AC input current up to 5000 Amps to a 0.333 Volt output.

The RCS-2400 is a 3 Phase Flexible Transformer kit that comes with three 24″ flexible rope coils (Rogowski Coils) and one integrator (signal conditioner) that converts the RopeCT voltage to 0.333 volt AC output. The integrator requires a DC power supply that operates between 9 and 36 Vdc.

The RCS-2400 allows for very wide ranges of input currents.  The product operates from 10% to 130% of the rated current with 1% accuracy.  For example, the RCS-2400-500, which is the 500A version, will be 1% accurate from 50A to 650A.  Each rope is 24″ long (~8″ diameter).

The RCS-2400 has these advantages in comparison to a traditional current sensor:

  • Greater linearity
  • High amperage measurement capability
  • Extremely flexible
  • Lightweight
  • Large circumference
  • No shorting block required

Compatible power meters accept a voltage input.  Look for meters on our website that start with this symbol:


If you are purchasing a Measurlogic, Veris or eGauge meter you do not need to purchase the RCS integrator (at least if ordered properly).  Instead, you can use QTY 3 of the passive RCT-2400-000 (that comes without the integrator) and save money.  If you are not using one of these 3 manufacturers, you will most likely need an integrator to compensate for the phase shift and low voltage output of the RCT-2400-000.

Note: The RCS-2400 integrator requires a power supply of 9 to 36 Vdc, which is not included. You may
purchase one here.
