SKMW40/DKMW40 40W DC-DC Converters

MEAN WELL SKMW40/DKMW40 DC-DC Converters offer standard pins, high efficiency of up to 91%, and 4:1 ultra-wide input range. These converters feature protections like continuous mode short circuit, overload, overvoltage, over-temperature, input under voltage, remote on/off, and trimmable output voltage. The SKMW40/DKMW40 converters come in a DIP 1"x1" package and comply with BS EN/EN55032 class A/B with additional components. Typical applications include electrical panels, telecommunication equipment, industrial automation, distributed power architecture, and transportation.
