RACM65S-K/277 are the new benchmark in power density for low power AC-DC power supplies with over 90% efficiency over a load range of 6 to 65

watts. Two different mounting options as encapsulated solder mount modules on industry standard P12+ pinning at 20 W/in³ or in an open chassis

mount structure with optional cover on a 1.5”x3” footprint with 31 mm overall height. International safety approvals according to medical, household and

industrial standards with OVC III rating up to 5000m operating altitude ensure worldwide use in ambient temperatures from -40 °C to 90 °C. The integrated EMC filter according to EN55032 Class “B” for floating loads only in the solder modules and additionally for grounded load connections in the chassis mount modules simplify system implementation.
