(auto - recovery mode). the power supply will recov er once the fault condition of the ocp is removed and output current is back within the specifications. short circuit protection (auto - recovery) the power supply?s output short circuit protection function also provides protection against short circuit s. when a short circuit is applied, the output current will operate in ?hiccup mode?. the power supply will return to normal operation after the short circuit is removed. overvoltage protection (latch mode) 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?. power supply will latch off, and require removal/re - application of input ac voltage in order to restart. the power supply should be latch. over temperature protection (latch mode) as described in load de - rating section, the power supply also has over temperature protection (otp). in the event of a higher operating temperature at 100% load; or, when the operating temperature is beyond what is recommended in the de - rating graph, the otp circuit will be activated. when activated, power supply will latch off, until the surrounding air temperature drops to its normal operating temperature or the load is reduc ed as recommended in the de - rating graph. removal/re - application of input ac voltage will then be required in order to restart. delta rohs compliant restriction of the usage of hazardous substances the european directive 2011/65/e u limits the maximum impurity level of homogeneous materials such as lead, mercury, cadmium, chrome, polybrominated flame retardants pbb and pbde for the use in electrical and electronic equipment. rohs is the abbreviation for ?restriction of the use of certain hazardous subst ances in electrical and electronic equipment?. this product conforms to this standard.
