## CUS600M and CUS600M1 Series 

## 3 x 5” 600W AC-DC Power Supplies 

https://product.tdk.com/en/power/cus-m www.emea.lambda.tdk.com/cus600m 

The compact CUS600M is packaged in the industry standard 3x5” footprint and can deliver 600W with forced air or 400W with a 600W peak power with convection cooling. With Medical & ITE certifications, the unit can used in both Class I & Class II (no ground wire) applications[(1)] .  A 5V 2A standby voltage, remote on/off, remote sense and a Power Good signal is standard on the CUS600M. Options include an internal fan and output adjustment. The CUS600M1 models offer a reduced feature set for cost optimization.
