Description

1. Buck-boost converter input voltage range is DC 5.5-30V; output voltage range is DC 0.5-30V, can be arbitrary adjustable; output current range is 0-4A, can be arbitrary adjustable, if enhance heat dissipation, it can reach 4A; max output power is 35W, output 3A 35W for long time stable work, if enhance dissipation, it can reach 50W.

2. Button control: Short press IN/OUT to switch input and output voltage, long press to switch output current power. Short press ON/OFF to control output ON or OFF, long press to set the default output state ON or OFF.

3. The voltage regulator module adopts LCD design, can switch display input voltage, output voltage, output current, output power; voltage display resolution is 0.05V, current display resolution is 0.005A.

4. The liquid crystal can display the input and output voltage and the output current output power, can be used for common boost and buck module with over current protection, adjustable battery charger, LED driver, etc

5. Safety protection: LC filter, small output ripple, input anti-reverse connection protection, will not burn down, short-circuit protection, low-voltage protection.

NOTE

Pay attention to wiring according to the diagram and do not make mistakes.
The input IN of the module is prohibited from short circuiting with the output OUT, otherwise the constant current function will fail.
Please ensure that the power of the power supply is always greater than the power required by the output load.
If the module wants to output at full load, the input voltage must be above 8V. When the input voltage is 5V, the output power is about 15W, and the voltmeter and ammeter will fail. The maximum current value of the module is 4A, subject to the maximum output power. For example, if the output is 17V, the current should not exceed 2A.
The module is equipped with output short-circuit protection. After short-circuit protection, the module automatically shuts off the output and can be restored by powering on the module again. If your power supply does not have output current limiting protection, it is recommended to connect a fuse in series at the input front of the module to improve the safety factor.

Module Function Description

The module has two buttons, IN/OUT and ON/OFF: the IN/OUT button switches between input voltage and output voltage display, and long pressing can switch between output current and output power display; The ON/OFF button controls the output to be ON or OFF. Long press to set the default output state to ON or OFF for the next power on.

CC is a potentiometer for current setting. Rotate clockwise to increase the set current. When the load current reaches the set current, it enters a constant current state and the CC constant current indicator light (red) lights up; The CV on the right is the voltage setting potentiometer, which can be rotated clockwise to increase the output voltage. The ON indicator light is an output status indicator light that lights up when there is voltage at the output terminal, otherwise it goes out.

Usage Method

Used as a regular boost/buck module with overcurrent protection capability.

Adjust the CV constant voltage potentiometer to achieve the desired output voltage.
Measure the output short-circuit current with a multimeter in 10A current mode (simply connect the two probes to the output terminal),Simultaneously adjust the CC constant current potentiometer to achieve the predetermined overcurrent protection value for the output current. (For example, if the current value displayed on the multimeter is 2A, then the maximum current when using the module can only reach 2A. When the current reaches 2A, the red constant voltage and current indicator light will turn on, otherwise the indicator light will turn off.)

Attention: When used in this state, due to the current sampling resistor at the output end, there will be a voltage drop of 0-0.2V when connected to the load. At the same time, when the current is high, there will be a certain online voltage drop between the input and output wires, which is a normal phenomenon!
