Low-profile switchers are medically sound

XP Power's latest low-profile medical AC/DC switchers, the PBM200 (200W) and PBM300 (300W), combine the flexibility of up to four outputs with an MTBF of over 300,000 hours (MIL-HDBK-217F at 25C) and full medical agency safety approvals. The PBM200 is 177.8 x 101.6 x 38.1mm and the PBM300 190.5 x 114.3 x 44.45mm. There are 22 models in the PBM200 series and 21 in the PBM300 family.

Output voltages are from 3.3 to 48V DC in single, dual, triple and quad-output versions.

Designed primarily for medical applications, the PBM200 comes complete with a cover and integral fan and produces 200W, the unit is also available as a 100W convection-cooled U-channel supply.

The equivalent PBM300 ratings are 300 and 150W, respectively.

PBM series power supplies have dual input fusing, meeting requirements for European medical systems without additional external fusing.

The units feature universal AC inputs of 90 to 264V AC, power density of up to 4.76W/in3 and up to 80% efficiency.

All models offer remote on/off and single output versions also have a remote sense function to compensate for up to 0.5V drop between the power supply output terminal and the load.

Overtemperature, overload, overvoltage and short circuit protection are all built in.

The PBM200 and PBM300 are available now.
