The CCM250 250-W ac/dc power supply is the first such unit to reach up to 95% efficiency. The supply saves space by employing a three-stage converter using an interleaved, resonant, half-bridge design that uses two small transformers to replace one larger transformer. The power supply measures 6 x 4 x 1.54 in., fits into a 1U enclosure, and targets medical, IT, and industrial systems.
The supply is convection cooled and delivers full output from 90 to 275-Vac input and 200 W at 80 Vac, at ambient temperatures from –10° to 50°C. The unit also supports short-term peak power needs of 300 W for 500 ms. Conducted and radiated emissions are below Class B limits defined by EN55011. ($195 ea/large qty — available now.)
