Various protections: Reverse connection protection—no damage from reverse connection; Backflow protection—direct battery connection without worrying about backflow damaging the module, no need for additional diodes; Overcurrent protection—output short circuit prevents damage; Battery current limiting ensures safety.
1.4. Includes a DC 5.5V input port and a USB adjustable voltage output interface.
1.5. Displays five parameters: input and output voltage, output current, power, and capacity.
1.6. Minimal output ripple; output includes LC filtering.
2. Product Parameters:
2.1. Input Voltage: 5-27V (The input voltage must be 2V higher than the output voltage. If you want to output 5V, the input voltage must be above 7V. If the output voltage cannot be adjusted, it may be because the potentiometer is rotated higher than the input voltage. You can first adjust thefor CVpotentiometer counterclockwise twenty turns to see the change in output voltage.)
2.2. Output Voltage: 1-24V (If the output voltage is higher than 24.5V, the output will automatically shut off and display 0V. After lowering the output voltage, press ONOFF.)
2.3. Output Current: The maximum output is about 3A. It is recommended to use it within 2.5A to avoid heat generation. 2.5. Output Current: You will need to handle the heat dissipation yourself. In constant voltage mode, the output current adapts to the load size and is not adjustable. (The adjustable current limit is approximately 3A. If the output current exceeds 3A, the output will automatically shut off and display OC. To resolve this, reduce the load current and press the ON/OFF button.)
2.4. Output Power: Less than 30W (If the output power exceeds 30W, the output will automatically shut off and display OP. To resolve this, reduce the load power and press the ON/OFF button.)
2.5. Voltage Display: Resolution 0.01V, factory accuracy approximately ±0.1V (For higher accuracy requirements, compare with a standard voltmeter.) (Manual calibration)
2.6. Current Display: Resolution 0.001A, range approximately 0-3A, factory accuracy approximately ±0.05A; display error is large when output current is less than 0.05A, and small currents within 10-40mA cannot be displayed (if high accuracy is required, manual calibration can be performed after comparison with a standard ammeter; calibration is more accurate when output current is greater than 1A).
2.7. Capacity Display: Resolution 0.001Ah, range 99.99Ah (can be cleared by long-pressing the '-' key; automatically saved after power failure and automatically accumulated after power-on. Saturation occurs after reaching 99.99Ah, requiring manual zeroing).
2.8 2.9. Conversion efficiency: Less than 95%
2.10. Operating current: Approximately 30mA
2.11. Input reverse connection protection: Yes
2.12. Output reverse current protection: Yes, can be directly connected to a battery for charging without adding a diode (the module output has an internal 1K ohm equivalent dummy load; continuing to connect the battery after charging will drain the battery power. If this is a concern, please connect a diode in series at the output).
2.13. Short circuit protection: Yes
2.14. Dimensions: 73.4mm (L) * 55.54mm (W) * 30.5mm (H)
2.15. Weight: 67.8g (including accessories, accessories weigh 41.5g)
