Note:
1. The power supply is considered a component which will be installed into a final equipment.
The final equipment must be re-confirmed that it still meets EMC directives.
2. All specifications are typical at nominal input, full load, at 25°C ambient unless noted. Consult
factory for information regarding testing for or usage under special environments.
Note:
Same dimensions for PCB & Pin Variants.
