CUS100ME Series 

2 x 4” 100W AC-DC Power Supplies 

https://product.tdk.com/en/power/cus-m www.emea.lambda.tdk.com/cus100me 

The compact CUS100ME is packaged in the industry standard 2x4” footprint.  The series can deliver 100W convection cooled at 50°C or up to 75W at 85°C with forced air. Conduction cooled, the CUS100M can deliver 100W at 70°C and 50W at 80°C.  With Medical & ITE certifications, the unit can used in both Class I & Class II (no ground wire) applications, and meets Class B Conducted and Radiated EMI. Enclosure options include a baseplate, U channel or U channel with a cover.
