Targeting the EV and VEH markets that require higher power converters that can be charged quickly, the DM1200 also features a large 45mm diameter opening that makes testing easier and more cost-effective, as frequent installation and replacement of the system under test can be carried out without the need to remove the primary cable connector.
Like all Danisense current sensors, the DM1200 is based on a closed-loop system, powered by a flux gate as a magnetic field detector. This zero-flux technology allows the DM1200 to exhibit excellent linearity.
Henrik Elbaek, CEO of Danisense A/S, comments: “The electric mobility industry is a game-changer for power converter measurement and testing tools. The increase in power combined with higher switching frequencies means we must offer higher-performing, robust, and highly accurate products, and the DM1200 is our first product specifically designed to meet all these requirements.”
The DM1200 also boasts a high bandwidth of up to 300 kHz to match the increased switching speeds, especially of SiC and GaN devices. To protect against EMC disturbances caused by these high-frequency signals, the DM1200 incorporates a metal housing for shielding. Horizontal and vertical mounting brackets are included to provide flexibility in the mechanical design of the test bench.
The DM1200 is part of a range of high-precision current sensing transducers from Danisense that ranges from 50 to 10,000 Arms.
