Technical Data Sheet RACM40-K Series ◊ AC/DC Power Supply 40W ◊ Input: 100V-240VAC **AC/DC Converter** ## FEATURES - 1.8“x3.2“x1.2”, encapsulated module - 40W power from -40°C up to +65°C ambient - Operating temp. up to +85°C with derating - OVC III, 4kVAC/1min reinforced isolation - 2MOPP medical certified - 5000m (medical/ITE) operating altitude - Class B EMC filter built-in - 3 year warranty Dimensions (LxWxH): 83.23 x 46.43 x 30.40mm (3.2 x 1.8 x 1.2 inch) 185g (0.41 lbs) ## APPLICATIONS SAFETY & EMC E314885 **==> picture [24 x 10] intentionally omitted <==** **----- Start of picture text -----**<br> P 14<br>**----- End of picture text -----**<br> ## DESCRIPTION The compact encapsulated industrial + household + medical grade AC/DC converter series RACM40-K delivers 40 watts of output power from -40°C to +65°C with natural air convection only, and up to +85°C with derating or forced air cooling. With a clear focus on extended thermal performance for systems where space is limited, these 1.8“ x 3.2“ compact modules are designed to gain highest overall efficiency levels over the full output load range from universal AC inputs. The RACM40-K has ANSI/AAMI/IEC 60601-1 medical safety and EN 60601-1-2 medical EMC certifications, 2MOPP, 4kVac/1min isolation and offers OVC III certified to IEC61558. It is additionally certified (CB Report) to IEC/EN 62368-1; IEC61010 and IEC61558-1/-2-16 for industrial applications and IEC/EN 60335-1 for household appliances. The robust built-in class B EMC filter has sufficient margin to allow either Class II or Class I PELV with grounded output installations. The mechanically rugged construction with fully potted encapsulation, 1.6mm pins and additional threaded inserts gives the series enhanced stability against shock and vibrations. |SELECTION GUIDE|||||| |---|---|---|---|---|---| |Part|Operating Input|Output Voltage|Output|Efficiency|Output Power| |Number|Range(3, 4)|nom.|Current nom.|typ.(2)|continuous| ||[VAC]|[VDC]|[mA]|[%]|[W]| |RACM40-05SK-T(1)|80-264|5|6000|87|30| |RACM40-12SK-T(1)|80-264|12|3334|90|40| |RACM40-15SK-T(1)|80-264|15|2667|90|40| |RACM40-24SK-T(1)|80-264|24|1667|90|40| |RACM40-48SK-T(1)|80-264|48|833|90|40| Note1: “-T” single layer tray packing.

About Novapart
Novapart is a B2B electronic component broker specialising in stock shortages and cost reduction. We source hard-to-find parts and identify compliant alternatives across a catalogue of 410,000+ components from 500+ manufacturers.
Learn more →Stock Shortage Specialist
When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.
Request a quote →Compliant Alternatives
We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
