NOTE

| 1. Efficiency, AC regulation and THD are tested by 400W, linear load at 12.5Vdc/25Vdc/50Vdc input voltage.

2. All parameters not specified above are measured at rated load, 25℃ of ambient temperature and set to factory setting. 3.Internal pre-start circuit, the setup time is 8s.

4.The power supply is considered as an independent unit, but the final equipment still need to re-confirm that the whole system complies with the EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”
