Specification Details

☑ The range of input voltage is from 90Vac to 264Vac with a single phase.

☑ Inrush Current (cold start): Will not exceed 80A at 100-240Vac input and Max load for a cold start at 25℃.

☑ PCB End Average Efficiency (at 115Vac and 230Vac): 5V/3A >81.39%, 9V/2.22A >85.47%, 12V/1.67 >85.48% (tested at 25%, 50%, 75%, and 100% of max load).

☑ Input power loss under no-load condition is less than 0.1W at 115Vac or 230Vac input.

☑ Export Protocol: Type-C USB. Supports USB Power Delivery (PD 2.0 & PD 3.0 protocol: 5V3A / 9V2.22A / 12V1.67A), Quick Charge 2.0/3.0, FCP, AFC, Apple 2.4A, DCP, and Samsung-5V-2A.

☑ Turn-on Delay Time: 3 seconds maximum at 100 Vac to 240 Vac input & full load.

☑ Hold-up Time: 5 milliseconds minimum at full load & 100Vac/60Hz input turning off at worst case.

☑ Capacitance Load: The adapter can turn on normally and output within rated range with a capacitance load of 2000uF at 100~240Vac input.

☑ Output Overshoot / Undershoot: Max 10% during power on or off.

☑ 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 and 8mS at 80%.

☑ Over Current Protection: Point limited: 5V (3-3.9A), 9V (2.22-3.33A), 12V (1.67-2.6A). Output enters hiccup mode and recovers automatically when fault is removed.

☑ Short Circuit Protection: Input power decreases during short circuit; power supply remains undamaged and recovers automatically when fault is removed.

☑ Over Voltage Protection: Under over-voltage state, protection is triggered (protection limit is ≤25V).

☑ Drop Test: Height of 1 meter onto a wood plank (min 53mm thickness) on concrete ground. Tested 2 times per side, 12 times in total.

☑ Plug-in Test: 10,000 insertion cycles total (Type-C USB: 5,000 times each). Normal appearance, structure, safety, and function after test; pullout force ≥5N.

☑ EMI Standards: Complies with FCC Part 15 class B, EN55032, and GB/T9254.

☑ EMS Standards: Complies with EN55035.

☑ Safety Standards: Accordance with UL62368-1, CSA C22.2 NO.62368-1, IEC62368-1, EN62368-1, AS/NZS 62368.1, and GB4943.1.

☑ Dielectric Strength (Hi-pot): Primary to Secondary: 3000VAC / 5mA Max / 60 seconds (3 seconds for mass production).

☑ Leakage & Insulation: Max 0.25mA leakage current at 264Vac/50Hz. Min 50MΩ insulation resistance at 500Vdc.

☑ Altitude Limit: Applicable up to 2000 meters in non-tropical conditions.
