Parameter:

1. Input voltage: 5-27V (The input voltage should be higher than the output voltage 2V. If you want to output 5V, the input voltage should be above 7V; if the output voltage cannot be adjusted, it may be because the potentiometer rotates above the input. Voltage, you can adjust the CV potentiometer for 20 turns to see the output voltage change.) The 24V battery can't be used, because the battery will fully charge more than 27V, which will damage the module.

2. Output voltage: 1-24V (output voltage is higher than 24.5V, auto-shutdown output, display 0V, after lowering the output voltage, press ONOFF button to solve)

3. Output current: The maximum output is about 3A. It is recommended to use in 2.5A. If the heat is large, you need to solve the heat dissipation problem. The output current in constant voltage mode is adaptive according to the load size, and it is not adjustable. (Adjustable limit current is about 3A, output current exceeds 3A, auto-shutdown output, display 0C, reduce load current, press ONOFF button to solve)

4. Output power: less than 30W (when the output power is greater than 30W, the output will be automatically turned off, and 0P will be displayed. After reducing the load power, press the ONOFF button to solve)

5. Voltage display: resolution 0.01V, factory accuracy ±0.1V (if the accuracy is high, it can be corrected manually after comparison with standard voltmeter)

6. Current display: resolution 0.001A, range 0-3A, factory accuracy ±0.05A; display error is larger when the output current is less than 0.05A, small current within 10-40mA can not be displayed (if high precision is required, Manual calibration after comparison with standard ammeter, calibration is more accurate when the output current is greater than 1A)

7. Capacity display: resolution O.OOlAh, range 99.99Ah (can be cleared by long button, automatically save after power failure, automatically accumulate after power-on. Saturated after reaching 99.99Ah, need to be manually cleared)

8. Conversion efficiency: less than 95%

9. Working current: about 30mA

10. Input reverse connection protection: Yes

11. Output anti-backflow: Yes, it can be directly connected to the battery for charging, no need to add diodes (there is a 1K ohm equivalent dummy load inside the module output. After the end of charging, the battery will lose battery power. Mind this, please The output is connected in series with a diode)

12. Short circuit protection: Yes

13. Size: 73.4 x 55.54 x 30.5mm (length x width x height )

14. Weight: 67.8g (including accessories, accessories weighing 41.5g)

Remind:

After the output voltage is adjusted to 5V, the USB port only provides 5V voltage. Some mobile phones can't be charged, such as IPHONE. It needs to short the D+D-bit of the two lines in the middle of the USB port, and now many mobile phones need to be intelligently recognized for charging. In order to charge and achieve fast charging effect. Therefore, the phone is not prompted to charge, or the charging speed is very slow. There may be only 500MA. You need to add the connector or other operation yourself. It is not a problem with the product or the current is not enough.

Package includes:

1 x Step down module

1 x Case kit
