500W-650W AC-DCs for Medical Devices including BF Applications

XP Power has announced two new ranges of ac-dc power supplies that provide BF class insulation for healthcare applications where excellent EMC performance is a key requirement.

The PBR500 and PBR650 series offer power levels up to 500W and 650W respectively. Both series accept a very wide, universal input range of 80- to 264-Vac 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 350W to 400W when convection cooled and 450W to 500W with external forced air cooling. The covered version, including a variable speed integral cooling fan for low audible noise, provides a complete 450W to 500W solution.

The PBR650 provides 600W to 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. Input to output isolation is 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

Both series include a 5V standby supply, overvoltage & overcurrent protection, remote sense and thermal shutdown. Also included is an ‘AC OK’ signal and remote on/off control. The u channel version of the PBR500 also provides a 12V 0.3A output suitable for powering system cooling fans.

The PBR500 / PBR650 are priced from $179.63 for 500 pcs orders and are available from Allied Electronics, Digi-Key, Newark, or direct from XP Power.
