Single class II series covers more medical applications, says XP Power

A range of 500W AC/DC power supplies that provide class II safety certification, including BF class insulation, for medical device applications requiring class II (without earth) installation, have been introduced by XP Power.

The PBL500 series offers power levels up to 500W forced cooled or 250W convection cooled, when fitted with an integral fan. The series accepts a wide, universal input of 80 to 264V AC at 47 to 63Hz and offers single output voltages from 12 to 57V. According to XP, system designers can cover many applications with the same series.

There are two formats available. The U-channel units provide 250W when convection cooled and 450 to 500W with external forced air cooling. The top fan cover version, including a variable speed integral cooling fan for low audible noise, provides 450 to 500W.

The product has a low patient leakage current and provides 2 x MOPP from input to case, 2 x MOPP from input to output and 1 x MOPP from output to ground. Input to case and input to output isolation is rated at 4000V AC and output to ground is 1500V AC. Both conducted and radiated emissions are class B, and the series complies with IEC/ES/EN 60601-1 edition 3.1 and 60601-1-2 edition 4

The PBL500 series includes a 5V standby supply, over-voltage and over-current protection, remote sense and thermal shutdown. There is also an ‘AC OK’ signal and remote on/off control. The U channel version also provides a 12V, 0.3A output suitable for powering system cooling fans.

The PBL500 series is available now from Digi-Key, Farnell, Mouser, RS Components, approved regional distributors, or direct from XP Power. All power supplies are covered by a three-year warranty.

XP Power provides AC/DC power supplies, DC/DC converters, high voltage power supplies and RF power supplies. Certified to ISO9001:2008, XP Power in-house design through to manufacturing facilities around the world. The company has 24 sales offices throughout Europe, North America and Asia.
