Product Description

Description:

1. Liquid crystal can display input and output voltage, output current output power;
2. The input end is anti-reverse protection, and the reverse connection will not burn;
3. It can be boosted, can be stepped down, the output voltage can be adjusted freely from 0.5-30V, and the current limit of 0-4A can be adjusted freely;
4. The output end is anti-backflowing, and there is no need to add an anti-backflow diode when charging the battery;
5. Press the button to control the output ON/OFF state, and you can set the power-on default to ON or OFF;
6. Using the buck-boost chip as the main controller, external 60V 75A MOS tube as the switch tube, dual 60V 5A SS56 Schottky for rectification, 60V withstand voltage value, better than the market XL6009/LM2577 immature solution (many The device withstand voltage is insufficient, the MOS tube and Schottky diode withstand voltage must be greater than the input plus input voltage value);
7. The output ripple is small and there is LC filtering;
8. With heat sink.

Product parameters:

Input voltage: 5.5-30V (when the input voltage is 5V, the buck-boost can also be realized, but the voltage and current measurement is not accurate; below 4.7V, undervoltage protection)
Output voltage: 0.5-30V
Output current: can work stably at 3A for a long time, and can reach 4A under enhanced heat dissipation
Output power: natural heat dissipation 35W, enhanced heat dissipation 50W
Voltage display resolution: 0.05V
Current display resolution: 0.005A
Conversion efficiency: about 88%
Soft start: Yes (large power with load module may fail when starting)
Input reverse connection protection: Yes
Output end anti-backflow: Yes
Short circuit protection: Yes
Working frequency: 180KHZ
Size: length * width * height 66 * 48 * 21mm
Mounting hole: diameter 4mm
Weight: 46g

Function Description:

1. The module has IN/OUT, ON/OFF two buttons: IN/OUT button switches input voltage and output voltage display, long press can switch output current output power display; ON/OFF button control output is ON or OFF, long press can Set the default output status of the next power-on to be ON or OFF.
2. CC sets the potentiometer for the current. It rotates clockwise to increase the set current. When the load current reaches the set current, it enters the constant current state, the CC constant current indicator (red) lights up; the right CV is the voltage setting. The potentiometer rotates clockwise to increase the output voltage. The ON indicator is an output status indicator that lights up when there is voltage at the output, otherwise it is off.
