New 500W-650W AC-DC Power Supplies for Medical Devices Including BF Applications

XP Power released PBR500 and PBR650 series, 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 feature power levels up to 500W and 650W respectively and accept wide, universal input range of 80VAC – 264VAC at 47Hz to 63Hz offering a total of eight single output voltages (12V, 15V, 18V, 24V, 28V, 36V, 48V & 57V). This gives the system designers the flexibility to cover many applications with the same series and offers the efficiency of 90% by reducing the heat generated during operation and prolonging the lifetime.

 

The PBR500 comes in two formats where the U channel format provides 350 – 400W when convection cooled and 450 – 500W with external forced air cooling. Also the covered version provides a complete 450 – 500W solution including a variable speed integral cooling fan for low audible noise. The other PBR650 series gives 600 – 650W in an enclosed supply with a variable speed integral fan with low audible noise similar to PBR500. The PBR500’s U channel version provides a 12V 0.3A output suitable for powering system cooling fans.

 

The PBR500 and PBR650 series products features 2 x MOPP from input to output and 1 x MOPP from both input to ground and output to ground with very low earth and patient leakage currents. The series features Input to output isolation rated at 4000VAC with input to ground and output to ground isolation rated at 1500VAC. Both conducted and radiated emissions are class B and both series are compliant with IEC/ES/EN 60601-1 edition 3.1 and 60601-1-2 edition 4. The PBR500 and PBR650 series offers 5V standby supply, overvoltage & overcurrent protection, remote sense and thermal shutdown including an ‘AC OK’ signal and remote on/off control.

 

The PBR500 and PBR650 series are now available and can be ordered from Digi-Key, element14, Farnell, RS Components, approved regional distributors, or direct from XP Power offered with a 3-year warranty.
