Medical AC/DC switchers offer 200 or 300W
XP Power’s latest medical, low-profile, 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 25 deg C) and full medical agency safety approvals. The PBM200 is 177.8 x 101.6 x 38.1mm (7 x 4 x 1.5 inches) and the PBM300 190.5 x 114.3 x 44.45mm (7.5 x 4.5 x 1.75 inches). There are 22 models in the PBM200 series and 21 in the PBM300 family. Output voltages are from 3.3VDC to 48VDC in single, dual, triple and quad-output versions.
DesiPBM 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 264VAC, power density of up to 4.76 Watts per cubic inch 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.
