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 stabilization.
5. Double heat sink design. MOS schottky diode independent heat sink,which heat dissipation is good,
and won't affect each other.
6. Using large size Sendust Core and double pure copper wiring, improve working efficiency, reduce fever.
