Specification Details
- 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 25℃.
- 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%.
