Product Description

1. Module properties: Non-isolated step-down constant current, constant voltage module (CC CV) charging module
2. Input voltage: DC 7-32V
3. Output voltage: (1) DC 0.8-28V continuously adjustable. (2) Fixed output:Choose between 0.8v-28v
4. Output Current: 8A (when power tube's temperature exceeds 65 degrees, please add cooling fan)
5. Constant current range: 0.2-8A ( 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).
7. Lowest pressure: 1V
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. Wiring: Terminal
17. No-load current: Typical 20mA (24V switch 12V)
18. Load regulation: ± 1% ( constant )
19. Voltage regulation: ± 1%
20. Dynamic response speed: 5% 200uS
21. 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)
22. Operating temperature: Industrial grade (-40 °C to +85 °C) ( please note the actual use
of the power tube temperature , high temperature heat strengthened)
23. Indicator: dual color indicator, charging indicator light is red, the green light means
fully charged ( No load is green )
24. Size(approx): 65 x 47 x 22mm (L x W x H)
25.Precision of constant current and temperature: On the actual test, the module temperature from 25 degrees
to 60 degrees, the constant current value change is less than 5% (5A constant current value)
26. Output short circuit protection: Yes,Constant current (the current setting constant current value)
27. Input reverse connect protection: NO
28. Output prevent reverse flow: NO
29. Wiring Method: amphenol connector

Features:
1. Fixed turn lamp current is 0.1 times the current value
( Used to identify whether the battery is fully charged When charging).
2. Made from a dedicated benchmark IC and high-precision current sensing resistor, proving a more stable
constant current, (when 20°C to 100°C constant current 1A, temperature drift less than 1%).
Particularly suitable for LED driver.
3. High output current, the max output current can reach 8A.
4. Four high frequency capacitance, can lower output ripple, enhance the work stabi
