AC-DC power supplies for medical devices
26 June 2019, Power Electronics / Power Management
XP Power has announced two new ranges of AC-DC power supplies that provide BF class insulation for healthcare applications where ehnanced EMC performance is a key requirement.
The PBR500 and PBR650 series offer power levels up to 500 W and 650 W, respectively. Both series accept a very wide, universal input range of 80 V – 264 V a.c. at 47 Hz to 63 Hz, and offer a total of eight single-output voltages (12 V, 15 V, 18 V, 24 V, 28 V, 36 V, 48 V and 57 V), 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 their lifetime. The PBR500 is available in two formats: the U-channel format provides 350 – 400 W when convection cooled and 450 – 500 W with external forced air cooling. The covered version, including a variable-speed integral cooling fan for low audible noise, provides a complete 450 – 500 W solution. The PBR650 provides 600 – 650 W 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 4000 V a.c. with input-to-ground and output-to-ground isolation rated at 1500 V a.c. 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 5 V standby supply, over-voltage and over-current 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 12 V / 0,3 A output suitable for powering system cooling fans.
