• Module properties: synchronous rifier non isolated step-down constant current constant voltage module CV charging module
• Scope of application: high power LED constant current drive, lithium battery charging (including ferroelrics), 4V, 6V, 12V, 14V, 24V battery charging, Ni Cd Ni MH battery (battery pack) charging, solar panels, wind power generator.
• Input voltage: 6-40VDC
• Output voltage: continuous adjustable (1.2-35VDC) for a long time of less than 32V (applied to the application of the input voltage higher than the output voltage can not be boosted)
• Output current: MAX 20A , long time work 15A (long time within the power tube temperature exceeds 65 degrees with the cooling fan, high voltage output to the amount of use)
• Limit range: 0.2-20A (adjustment) module is more than 65 degrees, please add the fan.
• Lowest voltage difference: 3V
• Working frequency: 150KHZ
• Conversion efficiency: MAX 96% efficiency is related to the pressure difference and the use envonment
• Output ripple: around 50mV of ripple (without noise) 20M bandwidth (reference only) input 24V
• Working temperature: -10 C to +75 C) (please pay attention to the temperature of the power pipe in actual use. Please strengthen the heat or reduce the use of the heat.)
• Potentiometer adjustment: clockwise (increase), counterclockwise (decrease)
• Output short ccuit protion: (instantaneous protion) constant current (current setting constant current value is not long short ccuited)
• Input back protion: No
• Output anti - reverse perfusion: No, for load power or inductive load needs additional 2 pole tube!
• Connion mode: terminal
• Module size: 60*53*30MM

The output current regulation method:

• adjust the CV potentiometer and set the output voltage to the voltage you need according to your load requement.

• a counter clockwise CC potentiometer of about 30 les (that is,set the output current to the minimum), conned to the LED, you need to adjust CC potentiometer current for battery charging, the battery is fully discharged, the output received again, adjusting CC to the current you need, (for charging must use a dead battery transfer is allowed because the battery remaining power increasing, the charging current is small).
