Specification
1. The range of input voltage is from 90Vac to 264Vac with a single phase.
2. The inrush current will not exceed 80A at 100-240Vac input and Max load for a cold start at 25ºC.
3. While input 115Vac and 230Vac, the average efficiency is more than 87.72%. The test point is at 25%, 50%, 75% and 100% of max load respectively.
4. While input 115Vac or 230Vac and the output is no load, the input power loss must be less than 0.1W.
5. While input 100~240Vac and capacitance load is 470uF, the adapter can turn on normally and the output is in the rated range.
6. Output Load Transient Response: the output shall not exceed 10% of the nominal output voltage, load fluctuation: from 20% to 80%, R/S: 0.5A/uS, frequency: 100Hz duration and 8mS at 80%.
7. Over Current Protection: I > 3.75A. The output shall hiccup when the over currents applied to the output rail, and shall be self-recovery when the fault condition is removed.
8. The input power shall decrease when the output rail short, the power supply shall no damage, and shall be self-recovery when the fault condition is removed.
9. The power supply shall protection when the output over voltage.
10. Drop in: Height: 1m; the product should be fell off on the plank with the thickness of at least 53mm, and the plank should be put on the cement ground or on the ground without flexibility. Random surface in all 3 times.
11. Burn-in: The power supply shall be burn-in at least 4 Hours under normal input and 80% rated load at 40ºC ± 5ºC.
12. MTBF Qualification: The MTBF shall be at least 50,000 hours at 25ºC, Full load and nominal input condition.
13. EMI Standard/EMI : EN55032
14. Safety Accord with IEC60601-1, EN60601-1. Note: AC pins corresponding to relative national standards.
15. Dielectric Strength(Hi-pot): Primary to Secondary: 4242VDC or 3000VAC / 5mA Max / 60 seconds (3 seconds for mass production).
16. Leakage Current: 0.1mA Max. at 264Vac / 50Hz.
