DCCT Transducers

High Precison Current Sensor


EPOWERSYS range of high performance current transducer allows the electronic measurement of DC, AC and pulsed currents with galvanic isolation between the primary (high power) circuit and the secondary (electronic) circuit with <±1ppm linearity and stability.


  • <±1ppm linearity and stability
  • DC current
  • AC current
  • Pulsed currents
  • ± 200A Primary Current
  • Zero-flux technology
    · High Bandwith
    · Extremely low temperature drift
    · Very low noise


  • Power Supplies
  • Biomedical Devices
  • Nuclear Magnetic Resonance (NMR)
  • Calibration Systems
  • Test and Measurement Setups


The core involved in AC measuring may saturate with DC currents, leaving residual permanent magnetism in it. This may result in measuring errors and lack of accuracy.
EPOWERSYS DCCT SERIES fix the problem of magnetic remanences with the degaussing function. This process is performed at the start-up of the device or may be performed manually.

EPOWERSYS DCCT SERIES fix the magnetic remanence problem with a degaussing function which runs each time the device is switched on. It can be performed at any time by user request as well.


The highest specification available

EPOWERSYS DCCT Series presents excellent linearity and extremely low noise thanks to an extremely accurate Zero Flux detector used in the closed loop.

Galvanic isolation allows measuring currents at a different potential and simplifies interfacing when using the EPOWERSYS DCCT in power supplies regulation.
