Data Sheet

Input condition : for rated voltage , Output condition : for max load
Ripple / Noise: 60Hz ripple + switching ripple and noise
Ripple & Noise are measured at the end of output cable which are added a 0.1uF
ceramic capacitor and a 47uF electrolytic capacitor
3-5. Over Voltage Protection
150% Max. of rated voltage.
The output voltage shall be shutdown and latch-off when OVP occurred
3-6. Over Current Protection
110%-170% of rated output current.
The adapter can withstand continuous short at DC output and no damage.
It will enter into normal condition if the fault condition is removed.
3-7. Short-Circuit Protection
The adapter can withstand continuous short at DC output and no damage.
It will enter into normal condition if the fault condition is removed.
3-8. Stability
2% Max. at constant load with constant input (after 30 minutes of operation).
3-9.Temperature Rise
Less than 55℃ on top/bottom case at normal AC input & 80% load of DC output at
environment temperature 25℃.
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
3-11. Voltage Isolation
The DC ground will be isolated from the AC neutral and AC line.
3-12. Over shoot
During either Turn-on or Turn-off of the power supply, the output voltage should not
exceed 1 10%Vo.No voltage of opposite polarity shall be present on the output during
turn-on or turn-off
4-0.Reliability
4-1. MTBF (MIL-HDBK-217F)
The power supply shall be designed and produced to have a mean time between failure ( MTBF) of
100,000 hours at 25 degrees C.
