Power Block

The Power Block series of both surface mount and pin thru hole power modules are industry standard power building blocks used with either digital or analog controllers as part of a power system. These blocks address the ever growing demands of higher power density and increased system level flexibility. Designed to operate from typical intermediate bus voltage levels between 7V and 13.2V, these power blocks were designed for superior power density with self-contained thermal management. Measuring 0.5″ x 1.0″ x 0.38″ and rated up to 30A of output current, the Bel Power Blocks boast a power density of 285W/in3 and a current density of 60A/in2. All products are RoHS EU Directive 2002/95/EC compliant.
