Consultation on Custom ParametersProduct Specifications and Parameters
Standard parameters can be customized and adjusted as needed.
Input characteristics
Rated voltage: 100 V–240 VAC
Adjustment range: 90–264 Vac
Rated frequency: 50/60 Hz.
Adjustable frequency: 47–63 Hz
Input Current: When the input AC voltage is at its lower limit and the load is fully loaded, the maximum input AC current is 0.3 A.
Inrush Current: When the output is at rated load, the ambient temperature is 25°C, and the input is 240 Vac with a cold start, the maximum inrush current is less than 50 A.
Output characteristics
Output voltage: 15.8V
Minimum load: 0.01 A
Output current: 0.8A
Output Power: 12.64 W
Ripple and Noise: Input Voltage (AC 110V–230V)
Test conditions: Under rated voltage and rated load, connect an oscilloscope with a 20 MHz bandwidth to the charger’s output terminal, and place a 10 µF electrolytic capacitor and a 0.1 µF ceramic capacitor in parallel at the output.
Efficiency: At an input of 230 Vac, the output efficiency shall average 76% under 25%, 50%, 75%, and full-load conditions (measured after 30 minutes of operation).
