EMC IMMUNITY

95% interruptions 250 periods

Efficiency, AC regulation and THD are tested by 1350W load, linear load at 12.5Vdc/25Vdc/50Vdc input voltage
No load disspation at non-saving mode(Typ.): 112/124/148 for 16W, 212/224/248 for 29W.
All parameters not specified above are measured at rated load, 25C of ambient temperature and set to factory setting.
Internal pre-start circuit, the setup time is 8s.
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.” (as available on http://www.meanwell.com)
