- ※ Note:  When the input voltage is AC 230V the model delivers EMI Class B  for both conducted emission and radiated emission for the power supply, When the input voltage is AC110V the model delivers EMI Class B  for conducted emission ,Class A for radiated emission for the power supply. 

   - It delivers Class A for conduted emission and radiated emission, when configured into ClassⅡ (without FG) system.

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.

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.
