KWS-A Series 

## Single output 5-25W AC-DC Board Mount Power Supplies 

https://product.tdk.com/en/power/kws-a www.emea.lambda.tdk.com/kws-a 

The industrial grade KWS-A series of 5W, 10W, 15W and 25W board mount  power supplies offer high efficiency levels of up to 88% in compact package sizes and footprints.  The KWS-A has a wide operating temperature range of -40 (start up) to +85°C with derating above 45/55°C and less than 0.5W off-load power consumption. These converters are Class II double insulated, allowing operation without an earth ground connection. 

|**Features**|**Benefits**|
|---|---|
|• High Efficiency, Up to 88%|• Lower Operating Costs, Improved Thermal Performance|
|• Class B EMI with an External X Capacitor|• Minimal External Components Required|
|• Low No Load Power Consumption|• Energy Saving|
|• Wide Operating Temperature|• Operation In Harsh Environments|
|• Class II, Wide Range Input (85-265Vac)|• Global Application, No Earth Required|
