Current transducer meets frequencies of wide bandgap technologies 

Offering extra-large bandwidth for high frequency applications, the DW series of closed-loop compensated zero-flux current transducers from Danisense are designed for the power measurement of GaN and SiC based converters.

The transducers measure up to 500A and offer 10ppm linearity accuracy and low offset (15ppm). Danisense has revised its winding processes to meet the increased frequency of the latest power conversion products based on wide bandgap semiconductor technologies such as gallium nitride (GaN) and silicon carbide (SiC). The DW500UB-2V transducers achieve a wide bandwidth of up to 10MHz.

All devices in the DW series have a full aluminium body for EMI shielding and a wide operating temperature range from -45 to +40 degrees C. They also have a very high power measurement accuracy, low noise and an industry standard BNC connection, added Danisense.

The main target application is power measurement in laboratories for the design optimisation of power converters – typically for e-mobility applications. The DW series current transducers can also be used for power measurement and power analysis for stable power supplies, MPS for particles accelerators, gradient amplifiers for MRI devices, precision drives, battery testing and evaluation systems and current calibration purposes.

Danisense was founded in 2012 and today is based in Denmark and Japan. The company’s founders and key employees are highly-experienced and possess specialised knowledge about high precision current transducers, enabling Danisense to create solutions that enable its customers to quickly and easy measure AC and DC currents with accuracies down to 1ppm. Its products have an extremely flat frequency response and outstanding DC stability.
