CUT35 Series 

https://product.tdk.com/en/power/cut www.emea.lambda.tdk.com/cut 

Dual and Triple Output 35W Low Profile Power Supplies 

The triple output CUT35 power supplies have two independent, isolated, converters, one for the main 5V output, and one for the auxiliary outputs. This topology provides several benefits - no minimum loading, enhanced load & line regulation and the ability to connect the auxiliary outputs in series to generate either a 24V or 30V output. The series is certified to both the IEC60601-1 and IEC62368-1 safety standards. Several mechanical configurations are available - open frame, an attached baseplate or with a baseplate and cover enclosure. 

|**Features**|**Benefits**|
|---|---|
|• 2 x 4 Footprint With a Low 1.06” (27mm) Height|• Space Saving in End Equipment|
|• Output 1 Isolated From Outputs 2 & 3|• Flexible Utilization|
|• No Minimum Loading|• Reduced Load Regulation|
|• Open Frame, Baseplate or Enclosed Formats|• Versatile Mounting|
|• Three Year Warranty|• Low Cost of Ownership|
