## Notes 

1. Ripple is peak to peak with 20 MHz bandwidth and 10 μF (Tantalum capacitor) in parallel with a 0.1 μF capacitor at rated line voltage and load ranges. 

2. Specifications are for nominal input voltage, 25°C unless otherwise stated. 

3. 400W with Forced cooling at 115 VAC to 264VAC. 

4. Combine Output Power of Main Output, Fan supply should not exceed 400 W. 

5. Output ripple can be more than 2 % of the output voltage.

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.
