Dent RoCoil Flexible 16" Current Transformer

The DENT RoCoil™Current Transformers have been designed for accurate non-intrusive measurement of AC current, pulsed DC or distorted waveforms where conventional rigid core CTs are unsuitable. This type of sensor may be used to measure AC current over a wide dynamic range and from 20 Hz to 5 kHz. Note: Some applications may require use of integrator/amplifier. See also RoCoil mV™.

*Depending on meter compatibility. RoCoil CTs UL Rated to 100KA AC.
ELITEpro SP/XC (v .212 or newer firmware) and PowerScout™ 3 and 24 (v. 3.16 or newer firmware) rated for 5-5000A. Meters with earlier firmware versions rated from 50-5000A AC.
PowerScout™18 rated for 50-3500A.
**Installed using best practices with conductor centered in the CT window and ensure any external conductors are a minimum distance of > 2X the diameter of the RoCoil. Accuracy below:
20A rated at 1.5% +/- 0.5A when used with DENT ELITEpro/PowerScout meters. RoCoil have been 100% verified to meet the C57.13-2008 Class 1.2 Standard.
