Specification Details
The range of input voltage is from 90Vac to 264Vac with a single phase.
Input AC Current: 0.15A max @ 100-240Vac input & Full load.
The inrush current will not exceed 50A at 100-240Vac input and Max load for a cold start at 25℃.
While input 115Vac and 230Vac, the average efficiency is more than 73.48%. The test point is at 25%, 50%, 75% and 100% of max load respectively.
While input 115Vac or 230Vac and the output is no load, the input power loss must be less than 0.5W.
While input 100~240Vac and capacitance load is 470uF, the adapter can turn on normally and the output is in the rated range.
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%.
Over Current Protection, Short Circuit Protection and Over Voltage Protection.
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.
The MTBF shall be at least 50,000hours at 25°C, Full load and nominal input condition.
Dielectric Strength(Hi-pot): Primary to Secondary: 4242VDC / 5mAMax / 60second (3 seconds for mass production).
Leakage Current: 0.25mAmax. at 264Vac / 50Hz.
Insulation Resistance: 50MΩ min. at primary to secondary add 500Vdc test voltage.
