XP Power has announced two new ranges of AC-DC power supplies that provide BF class insulation for healthcare applications where EMC performance is a key requirement. The PBR500 and PBR650 series offer power levels up to 500W and 650W respectively. Both accept a very wide, universal input range of 80VAC – 264VAC at 47Hz to 63Hz and offer a total of eight single output voltages (12V, 15V, 18V, 24V, 28V, 36V, 48V & 57V), giving system designers the flexibility to cover many applications with the same series. Both series offer efficiencies of 90%, reducing the heat generated during operation and prolonging the lifetime. The PBR500 is available in two formats. The U channel format provides 350 – 400W when convection cooled and 450 – 500W with external forced air cooling. The covered version, including a variable speed integral cooling fan for low audible noise, provides a complete 450 – 500W solution. The PBR650 provides 600 – 650W in an enclosed supply also with a variable speed integral fan with low audible noise. The products have very low earth and patient leakage currents and provide 2 x MOPP from input to output and 1 x MOPP from both input to ground and output to ground. ...
