Specification Details
1. The range of input voltage is from 90Vac to 264Vac with a single phase.
2. Inrush Current (cold start): 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:
• 5V/3A PCB end average efficiency > 81.39%
• 9V/2.22A PCB end average efficiency > 85.47%
• 12V/1.67 PCB end average efficiency > 85.48%
(Test points at 25%, 50%, 75%, and 100% of max load).
4. While input 115Vac or 230Vac and the output is no load, the input power loss must be less than 0.1W.
5. Export protocol: Type-C USB supporting USB Power Delivery (PD) 2.0 and 3.0: 5V3A / 9V2.22A / 12V1.67A. Supports Quick Charge 2.0/3.0, FCP, AFC, Apple 2.4A, DCP, Samsung-5V-2A.
6. Turn-on Delay Time: 3S max. @ 100 Vac to 240 Vac input & Full load.
7. Hold-up Time: 5mS min. @ Full load & 100Vac/60Hz input turn off at worst case.
8. Capacitance Load: While input 100~240Vac and capacitance load is 2000uF, the adapter can turn on normally and the output is in the rated range.
9. Output Overshoot / Undershoot: 10% max. when the power turns on or off.
10. Output Load Transient Response: output shall not exceed 10% of nominal output voltage (load fluctuation: 20% to 80%, R/S: 0.5A/uS, frequency: 100Hz, duration: 8mS at 80%).
11. Over Current Protection: limited points: 5V:3-3.9A, 9V:2.22-3.33A, 12V:1.67-2.6A. Output shall hiccup under over-current and self-recover when removed.
12. Short Circuit Protection: Input power decreases during output short circuit. No damage occurs, and it self-recovers once resolved.
13. Over Voltage Protection: The power supply protects when output exceeds limits. Overvoltage protection is ≤25V.
14. Drop Test: Height: 1m; dropped onto a plank (thickness ≥53mm) on a cement floor. Two times per side, 12 times total.
15. Plug-in Test: Tested for 10,000 insertion cycles (insertion force ≤20N, pull force ≥5N). Type-C USB tested 5,000 times each (10,000 total). Structure and safety remain normal.
16. EMI Standards: FCC Part15 class B, EN55032, GB/T9254.
17. EMS Standards: EN55035.
18. Safety Standards: UL62368-1, CSA C22.2 NO.62368-1, IEC62368-1, EN62368-1, AS/NZS 62368.1, GB4943.1.
19. Dielectric Strength (Hi-pot): Primary to Secondary: 3000VAC / 5mA Max / 60 seconds (3 seconds for mass production).
20. Leakage Current: 0.25mA max at 264Vac / 50Hz.
21. Insulation Resistance: 50MΩ min at primary to secondary with 500Vdc test voltage.
22. Nontropical Altitude: 2000m.
