  • Patent number: 6678181
    Abstract: An industrial power supply module includes a heatsinking structure, e.g., an extruded aluminum structure, comprising a plurality of walls joined to define a channel. first and circuit board assemblies comprising respective booster and DC/DC converter circuits are mounted to the heatsinking structure such that at least portions of the circuit board assemblies lie in the channel. First and second end caps are attached to the heatsinking structure at respective first and second ends of the channel. Environmental seals may be provided at the first and second ends of the channel. The booster circuit may be operative to produce a first DC voltage and the DC/DC converter circuit may be operative to produce a second DC voltage from the first DC voltage such that the second DC voltage is at least about ten times less than the first DC voltage.
