Multi format 180-W, 93% efficient power supplies have medical approval

September 06, 2013 // By Graham Prophet
XP Power's GCS series now includes single-output high efficiency AC-DC power supplies with both ITE and Medical safety approvals. Complementing the GCS150 150W models, the GCS180 range extends the power output capability up to 180W.

All models in the range have a no-load input power of less than 0.5W and a typical efficiency of 93%. The GCS180 series is available in multiple mechanical formats giving the designer several mounting configurations to choose from to suit the end application. Convection-cooled formats, providing up to 150W output, are in an industry standard 3 x 5 in. (127 x 76.2 mm) open frame package: an optional enclosed cover option is also available. The full 180W output is available when a forced air flow of 7 CFM is provided by the user or by using the optional top or end mounted fan formats.

Across the range, five single output models are available covering the popular nominal outputs of +12, +15, +24, +28 or +48 VDC. An additional 12V / 0.6A fan output is standard. Designers also have the choice of using an input earth connection, or not, due to the Class I and Class II input construction used. A remote on/off feature is available. The GCS180 series meets the Class B limits of EN55011 and EN55022 for conducted emissions and Class A limits for radiated emissions with no additional filtering components required. Complying with the IT equipment safety specifications of UL/EN60950-1 and the current 3rd edition medical safety standards of EN60601-1, ES60601-1 and CSA22.22 No 60601-1 per cUL, the GCS180 series is suitable for a wide range of medical, industrial and communication applications. With a wide range of operating temperature, from – 40 to + 70 degrees C, the units can be used in most environments. There is no derating until above + 50 degrees C. From Farnell-element14, or from;
