Current sensing is a critical element of most power supplies. Addressing the technological needs of the next generation of power supplies WCM has developed a number of products for both linear and switched applications. The design philosophy embodied in these products was to create very compact, highly linear, magnetic based current sensors, with robust isolation to satisfy global safety agency requirements. For switched applications WCM has a number of sensing transformers that can accommodate up to 50 amps of current, in both through-hole and surface mount configuration, with a frequency range from 10 kHz to 500 kHz. On the linear side, WCM offers a great through hole product with a highly linear response up to 500 amps. If you don’t see what you want in our standard products, contact us for a custom design.
