The P-DUKE MAF150US28B is an open frame AC/DC converter from the MAF150 series, designed for medical and ITE applications. It accepts a wide input voltage range of 85-264VAC and provides a regulated 28VDC output. Under natural convection cooling, it delivers 110W (3.93A); with forced air cooling (10CFM), it can deliver up to 150W (4.83A). The converter achieves up to 92% efficiency and includes active power factor correction (0.95 typical).
Electrical specifications include 4000VAC input-to-output isolation with 2xMOPP insulation, low leakage current under 100µA, and a hold-up time of 16ms at 115VAC full load. Output voltage is adjustable by ±10%. The unit features line regulation of ±0.2% and load regulation of ±0.5%. It operates over a temperature range of -25°C to 85°C with derating, and at altitudes up to 5000m.
The converter is chassis-mountable with an open frame package measuring 101.6mm x 50.8mm x 29.5mm (4.00" x 2.00" x 1.16"). It is certified to IEC/EN/ANSI/AAMI 60601-1 (medical) and IEC/UL/EN 62368-1 (ITE) safety standards. The MAF150US28B is suitable for medical equipment, industrial controls, telecom, and datacom applications.
