Magnelab’s RCS-1800 is a 3 Phase Rogowski Coil that transforms an AC input current up to 5000 Amps to a 0.333 Volt output.
The RCS-1800 is a 3 Phase Rogowski Coil kit that comes with 3 RopeCTs (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-1800, like other Rogowski coils, allows for very wide ranges of input currents. The product is designed to operate from 10% to 130% of the rated current with 1% accuracy. For example, the RCS-1800-250, which is the 250A version, will be 1% accurate from 25A to 325A. The RCS-1800 has three lengths, each 18″ long (~6″ opening).
The RCS-1800 has these advantages in comparison to a traditional CT:
- Greater linearity
- High amperage measurement capability
- Extremely flexible
- Large circumferences available
- 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-1800-000 (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-1800-000.
Note: The integrator requires a power supply of 9 to 36 Vdc, which is not included. You may
