Features:

Use a dedicated benchmark IC, and high-precision current sensing resistor, make more stable constant current, (when 20°C to 60°C constant current 5A, temperature drift less than 5%). suitable for LED driver.
Fixed turn lamp current is 0.1 times the current value (When charging, used to identify whether the battery is fully charged);
High output current, the max output current can reach 8A.
Low output ripple , high frequency capacitor reduces output ripple.

Module parameters:

Module Properties: non-isolated step-down module, constant current and constant voltage module (CC CV), charging module
Input voltage: 7-40V
Output voltage: 1.2-35V (continuously adjustable)
Output Current: 8A Max ( power tube temperature exceeds 65°C please add cooling fan )
Constant current range :0.2-8A ( adjustable )
Dropout voltage: 1V
Output Power: <300W
Conversion efficiency : <95%
Operating frequency: 180KHZ
Output ripple : 20M bandwidth ( for reference only )
Input 24V Output 12V 5A ripple around 50mV ( excluding noise )
Operating temperature : Industrial grade (-40 °C to +85 °C)
No-load current : Typical 20mA (24V step down to 12V)
Load regulation : ± 1% ( constant voltage)
Voltage regulation : ± 1%
Dynamic response speed : 5% 200uS
Output short circuit protection : Yes , constant current ( constant current value you set)
Input Reverse Polarity Protection: None
Output prevent backflow : None.
Wiring: Terminal
Size:65(L)*47(W)*23.5(H) mm

Applications:

High-power LED constant current drive ,
Lithium battery(or Iron battery) charge,
6V, 12V, 14V, 24V battery charge ,
Nickel-cadmium nickel-metal hydride battery ( battery pack ) charge ,
Solar panels and wind turbines

Potentiometer adjustment:

clockwise ( increase ) , counterclockwise ( decrease ). The potentiometer close to the input port is for voltage adjust (CV), the potentiometer close to the output port is for current adjust(CC).

Indicator : double color indicator. When charging the indicator is RED, fully charged is GREEN( No load is green ).

How to charge the battery or light the LED:

Determine the float voltage and charging current of the battery you need to charge, and the input voltage of the module.
Adjust the constant voltage potentiometer to adjust the output voltage to about 5V.
Use the 10A current block of the multimeter to measure the output short-circuit current, and adjust the constant current potentiometer to make the output current reach the predetermined charging current value.
Adjust the constant voltage potentiometer to make the output voltage reach the floating voltage.
Connect the battery/LED.

(Steps 1, 2, 3 and 4 connect the power supply to the module input, and do not connect the battery to the output without load.)
