This module adopts boost and buck chip as the main controller, external 60V 75A MOS tube as the switch tube, double 60V 5A SS56 schottky rectifier, 60V voltage withstand value, more stable and reliable performance, is a good adjustable step-down/up constant voltage constant current solution.

Input Voltage: 5.5-30V (If the input voltage is 5V, measurement is not accurate. Less than 4.7V, low-voltage protection.)
Output Voltage: 0.5-30V
Output Current: 3A for long time stable work, can be up to 4A after enhancing heat dissipation.
Output Power: 35W in natural heat dissipation, up to 50W after enhancing heat dissipation.
Output Indicator: Constant current indicator light, output indicator light
Voltage Display Resolution: 0.05V
Current Display Resolution: 0.005A
Transfer Efficiency: Approx. 88%
Soft Start: YES (High power load module may fail when started)
Input Reverse Protection: YES
Output Anti-Backflow: YES, No additional anti-backflow diode is required for battery charging
Short circuit protection: YES, After short circuit protection, the module automatically shuts down the output, and be restored after re-energizing.
Low-Voltage Protection: The default is about 4.7V, the output will be automatically disconnected if less 4.7V
Operating Frequency: 180KHz
Size: 66x48x21mm (LxWxH)
Mounting Hole: 4mm

Package Include:
2 x Step-down/up power converter module

Note:
1.The module has IN/OUT, ON/OFF two buttons:IN/OUT button switches input voltage and output voltage display, long press to switch output current output power display;
ON/OFF button control output ON or OFF, long press can set default output state is ON or OFF when powered next time.

2. CC is current setting potentiometer, clockwise rotation can increase setting current, when the load current reaches setting current, it enters constant current state, and CC constant current indicator light (red) lights up;
