ZWS-BAF Series 

## 33 to 302W Single Output, High Reliability Power Supplies 

https://product.tdk.com/en/power/zws-baf www.emea.lambda.tdk.com/zws-baf 

The ZWS-BAF industrial grade power supplies are used in a wide range of applications where equipment down-time cannot be tolerated during years of operation.  Globally, process control, test and measurement equipment, machinery, semiconductor fabrication, communications and large LED display manufacturers depend upon the ZWS-BAF to provide a reliable source of power.  Conservatively rated electrolytic capacitor temperatures offer improved field life-times of up to 10 years.  Available in five power levels, 50W, 75W, 100W, 150W and 300W, the series provides a choice of 3.3 to 48V outputs. A variety of mechanical configurations are available, in addition to a double sided board coating option. 

|**Features**|**Benefits**|
|---|---|
|• 10 Year Electrolytic Capacitor Lifetimes|• Improved Field Life|
|• Convection Cooled|• Reduced Dirt and Dust Contamination|
|• Curve B Radiated and Conducted EMI|• Easier System Compliance|
|• 5 year Warranty|• Low Cost of Ownership|

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Request a quote →

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
