MAF150US18B

The P-DUKE MAF150US18B is an open-frame AC/DC converter from the MAF150 series, designed for medical, industrial, and ITE applications. It accepts a universal input voltage range of 85 to 264 VAC and provides a single regulated output of 18 VDC. Under natural convection cooling, it delivers 6.12 A (110 W); with forced air cooling, output increases to 7.5 A (150 W). Efficiency reaches 92%, reducing power loss. The converter features active power factor correction (PFC) and a built-in EMI filter, minimizing input harmonics and conducted emissions. Standby power consumption is less than 0.3 W. Input-to-output isolation is 4000 VAC with 2xMOPP reinforced insulation, suitable for medical equipment. Leakage current is below 100 µA. The output voltage is adjustable by ±10%. Protection includes overcurrent, overvoltage, and short circuit. Operating temperature range is -25°C to 85°C with derating. The unit is chassis mount with dimensions 101.6 mm x 50.8 mm x 29.5 mm (4.00" x 2.00" x 1.16"). Safety certifications include IEC/EN/ANSI/AAMI 60601-1, IEC/UL/EN 62368-1, CB, CE, cURus, and FCC. The converter is suitable for both Class I and Class II installations.
