• Category: Arduino & SCM Supplies

1. Input voltage: 4 - 35V (Note: for constant current input, the minimum required is 7V or above)
2. Output voltage: 1.25 - 25V adjustable continuously, default shipping voltage is 4.2A with a current of 1A
3. Output current: 12V to 5V, 2A (Constant current range: 0.2A - 2A adjustable)
4. Transistor current: fixed at 1/10 of the set constant current value
5. Output power: natural cooling 10W, 15W requires a heat sink installation
6. Conversion efficiency: 80% (The higher the output voltage, the higher the efficiency)
7. Operating temperature: industrial grade -40°C to +85°C (If the ambient temperature exceeds 40°C, reduce the power usage or enhance the heat dissipation)
8. Full-load temperature rise: 45°C
9. Indicator lights: constant current indicator light is red, charging in progress indicator light is red, charging complete indicator light is green
10. Output short-circuit protection: yes, for constant current (current set at the current value)
11. Wiring method: can be directly wired and soldered onto the PCB
12. Adjustment method: first, connect the input power correctly (between 4 - 35V), then use a multimeter to monitor the output voltage and adjust the potentiometer (generally, rotate clockwise to increase voltage, counterclockwise to decrease voltage)
13. Size: about 5 x 3.7 x 1.3 cm
