Over Load

110%~150% of rated current, Constant current limiting for some time(150% of rated current, last 3S) then PS stop working for 7S,after 7S,if the load <=rated current, PS will work normally, auto recovery

Over voltage

29~33V, hiccup mode, Auto recovery

56~63V, hiccup mode, Auto recovery

Over temperature

NOTE

1. All parameters NOT specially mentioned are measured at rated input, rated load and25℃of ambient temperature.

2. Measured at 20MHz of bandwidth by using a12”twisted pair-wire terminated with a 0.1 uF & 10uF parallel capacitor.

3.The power supply is considered as a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies” on https://www.powerld.com.
