DC/CC Adjustable 0.2- 9A 300W Step Down Buck Converter 5-40V To 1.2-35V Power Supply Module LED Driver
1. Module properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module
2. Input voltage: DC 5-40V
3. Output voltage: DC 1.2-35V continuously adjustable
4. Output Current: 9A (when power tube's temperature exceeds 65 degrees, please add cooling fan)
5. Constant current range: 0.2-9A ( adjustable )
6. Turn lamp current: Constant current value * ( 0.1 ) , turn the lamp current and constant value linkage,
such as constant current value is 3A, turn the lamp current is set to a constant current is 0.1 times (0.1 * 3A = 0.3A).
8. Output Power: Maximum power is about 300W
9. Conversion efficiency: Up to about 95%
10. Operating frequency: 300KHZ
11. Output ripple: 20M bandwidth
12. Input 24V output 12V 5A ripple around 50mV (Excluding noise)
13. Output short circuit protection : Yes, constant current
14. Input reverse polarity protection: None
15. Output prevent backflow: None
16. Potentiometer adjustment direction: clockwise (increase) , counterclockwise (decrease),
the potentiometer(CV) closed to the input voltage is used to regulate voltage, the potentiometer(CC)
closed to output voltage is used to regulate current (CC)
17. Operating temperature: Industrial grade (-40 °C to +85 °C) ( please note the actual use
of the power tube temperature , high temperature heat strengthened)
18. Indicator: dual color indicator, charging indicator light is red, the green light means
fully charged ( No load is green )
19. Size(approx): 65 x 47 x 22mm (L x W x H)
Battery charge:
1. Make sure of the battery float voltage and charging current that you need, as well as the input voltage of the module.
2. Adjust the constant voltage potentiometer and adjust the output voltage to about 5V.
3.Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the
current potentiometer to make the output current to the expected charging current value.
4. Adjust the constant voltage potentiometer to make the output voltage reaches the float voltage.
5. Connected to the battery, try to charge.
(1,2,3,4 steps to connect the power module input,output no-load does not connect battery.)
LED constant current drive:
1. Make sure the operating current and Max operating Voltage of the LED you need to drive.
2. Adjust the constant voltage potentiometer, adjust the output voltage to about 5V.
3. Use the multimeter in 10A current scale to measure output short-circuit current, and adjust the current
potentiometer to make sure the output current to the expected LED operating current.
4. Adjust the constant voltage potentiometer to make the output voltage reach the maximum LED operating voltage.
5. Connect LED, test.
(1,2,3,4 steps to connect the power module input, output No-load does not connect LED.)
