(auto - recovery). the power supply will recover once the fault condition of the olp and ocp is re moved and i o is back within the specifications. it is not recommended to prolong the duration of i o when it is <150% but >100%, since it may cause damage to the psu. short circuit protection the power supply?s output olp/ocp function also provides protection against short circuits. when a short circuit is applied, the output current will operate in ?hiccup mode?, as shown in the illustration in the olp/ocp section on this page. the power supply will return to normal operation after the short circuit is removed. overvoltage protection the power supply?s overvoltage circuit will be activated when its internal feedback circuit fails. the output voltage shall not exceed its specifications defined on page 3 under ?protections?. the power supply doe sn?t shut down but goes in 2 nd level regulation at 30- 32vdc and continue to deliver the power. according to high output vo ltage which will be operating > 100% of rated load (32v rated output current), if this condition persists, the power supply will sense otp (over temperature protection) and will go under hiccup mode. the power will return to normal operation once the fault condition is removed . over temperature protection as m entioned above, the power supply also has over temperature protection (otp). i n the event of a higher operating temperature at 100% load , the power supply will run into otp when the operating temperature is beyond what is recommended in the de - rating graph. when activated, the output voltage will go into bouncing mode until the temperature drops to its normal operating temperature as recom mended in the de - rating graph.
