Datasheet

3-5. Short circuit protection :
The output should shut-down when subjected to a short circuit(R<0.3R). After shut-down the
power supply shall return to normal operating conditions after removing the short situation .
3-7. Over Power Protection :
180% of max current
When Over-Power occurred the output should be shut down and the over –current
Situation is removed the output shall be auto-recover without any harm .
3-8. Stability
2% Max. at constant load with constant input (after 30 minutes of operation).
3-9.Temperature Rise
Less than 45°C on top/bottom case at normal AC input & 80% load of DC output at
environment temperature 25 °C.
3-10. Drop-out (Power Line Disturbance)
Output voltage shall remain within the specified regulation range, through the absence of
a line input during 1/2 cycle, at full load and normal AC line input
4.Reliability Specification
4-1. MTBF (MIL-STD-781C)
The power supply shall be designed and produced to have a mean time between
failures (MTBF) of 30000 operating hours minimum conditions: 80% maximum load at
25 °C, nominal input voltage
.
