(auto - recovery). the power supply will recover once the fault condition of the olp and ocp is removed and i o is back within the specifications. additionally, if the i o is < 1 2 0 % but > 100% for a prolong period of time (depending on the load), the over temperature protection (otp) will be activated due to high temperature on critical components. the power supply will then go into ?hiccup mode? until power supply cool down. over t emperature protection as mentioned above, the power supply also has over temperature protection (otp). this is activated when the overload condition persists for an extended duration and the output current is below the overload trigger point but > 100% loa d. in the event of a higher operating condition at 100% load, the power supply will run into otp when the surrounding air temperature is > 75c . when activated, the output voltage will go into bouncing mode until the operating surrounding temperature drops to 50c or output capacity is reduced as recommended in the de - rating graph. 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 ope rate 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.
