Current transducer provides extra-large bandwidth for high-frequency applications

Danisense introduces its new DW series of closed-loop compensated zero-flux current transducer measuring up to 500A and providing exceptional accuracy with 10ppm linearity and low offset at 15ppm. To satisfy the increased needs in terms of high frequency coming from the latest power conversion products based on wide bandgap semiconductor technologies such as GaN and SiC, it has revised its winding processes. It now achieves an exceptionally wide bandwidth of up to 10MHz with its latest DW500UB-2V product.

The series devices benefit from a full aluminium body for superior EMI shielding and a wide operating temperature range from -45C to +40C. Further features include high power measurement accuracy, low noise, and an industry-standard BNC connection. The main target application is power measurement in laboratories for the design optimisation of power converters - generally for e-mobility applications. The series current transducers can also be utilised for power measurement and analysis for stable power supplies, MPS for particle accelerators, precision drives, gradient amplifiers for MRI devices, battery testing and evaluation systems and current calibration purposes.
