Ultra High Voltage BCM Modules


Go to High Voltage Bus Converter Module »


The Ultra High Voltage BCM is a high efficiency K=1/16 fixed ratio converter operating from either a 400 - 700 V primary input to produce an unregulated SELV DC output voltage. Initial products are available in the Vicor Integrated Adapter (VIA) package which simplifies customer cooling approaches as well as providing integrated PMBus control, EMI filtering, and transient protection.
