240 W Medical AC/DC Open frame Switching Power Supply; 12 VDC 20 A MQF500O-12S

The MQF500O series of compact low profile open frame Medical AC-DC power supplies comprises 3 models offering a single regulated output to 240 W providing all the popular nominal output voltages from +12 to +48 VDC.

With power factor correction (PF>0,94) these highly efficient units, typically >90% efficiency, measure just 127,8 x 76,2 x 35 mm (5.03” x 3” x 1.38”) feature 4000 VAC or 5656 VDC isolation, low component density, low profile, high efficiency, high reliability and long life and fit into an industry standard footprint.

The MQF500O are convection cooled units, with no additional forced air cooling being required to reach nominal 240 W output power. When using only 30 CFM of forced air flow, or by specifying an optional fan model, the full output power of 500 Watts is available. They are capable of operating over a wide range of temperatures from -30 to + 70°C (with derating).

Meeting the IT equipment safety specifications of UL 60950 and Medical safety specifications of ANSI/AAMI ES60601-1 and CAN/CSA 60601-1 and 2xMOPP, the series suit a broad range of medical, information technology and industrial equipment. They also comply with the EN61000-4 and EN55011 class B standard for conducted emissions without the need for additional filtering components.
