PROTECTION

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

28.8~33V, constant voltage, Auto recovery

Over temperature

105±5, detect on heat sink of power transistor; shut down O/P, auto recovery after temperature goes down.

Short Circuit

Long-term mode, auto recovery

NOTE

1. All parameters NOT specially mentioned are measured at rated input, rated load and 25 of ambient temperature.

2. Measured at 20MHz of bandwidth by using a 12” 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” onhttp://www.powerld.com.cn.
