The RCS-900T is a three-phase RopeCT by Magnelab that transforms an AC input current up to 5000 Amps to a 0.333 Volt output.
The RCS-900T is a three-phase RopeCT 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-900T has a 9″ opening and is made of very flexible material, allowing it to easily fit around conductors. If a true circle is not needed, such as in the case of a bus bar, the 9″ opening can be stretched to become much larger (1 ft or more).
The teardrop design of the RCS-900T allows for superior centering of the Rogowski coils (all Rogowski coils encounter small error if they are not perfectly centered). It is designed to allow a zip tie to be secured around the Rogowski coil, perfectly centering the primary conductor.
The RCS-900T, like other Rogowski coils, allows for very wide ranges of input currents. The product is designed to operate from 10 to 130of the rated current with 1accuracy. For example, the RCS-900T-250, which is the 250A version, will be accurate from 25A to 325A.
The RCS-900T 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-900T-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-900T-000.
Note: The integrator requires a power supply of 9 to 36 Vdc, which is not included.
