Module parameters
Modular nature: synchronous rectification non-isolated step-down constant current constant voltage module CC CV charging module
Applications: High-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride batteries (battery pack) charging, solar panels, wind turbines
Input voltage: 6-40VDC
Output voltage: continuously adjustable (1.2-35VDC) for a long time 32V (for the input voltage is higher than the output voltage of the application can not be boost)
Output current: maximum 20A long time 15A (power tube temperature exceeds 65 degrees please add fan cooling, high voltage output please derating use)
Limiting range: 0.2-20A (adjustment) module over 65 degrees Please add fan.
Minimum differential pressure: 3V
Working frequency: 150KHZ
Conversion efficiency: up to about 96% efficiency with pressure and use of the environment
Output ripple: Ripple 50mV (no noise) 20M Bandwidth (for reference only) Input 24V measured
Working temperature: -10 to +75 ) (practical use, please pay attention to the power tube temperature, the temperature is too high, please strengthen the use of heat or derating)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (reduced)
Output short circuit protection: Yes (instantaneous protection) Constant current (current set constant current value can not be short time short circuit)
Input Reverse Protection: None,
Output anti-flooding: none, for the load from the charged or inductive load need to add 2 transistor!
Wiring method: terminal block
Module size: 60 * 53 * 30MM
Output current regulation method:
1, adjust the CV potentiometer, according to your load requirements, the output voltage is set to the voltage you need.
2, counterclockwise set CC potentiometer 30 or so,( 59130121,that is, the output current is set to minimum), connected to the LED, adjust the CC potentiometer to your current. For the battery charge, the battery after the termination of power, then receive the output, adjust the CC to the current you need,( 59130122,for charging must be used to put the battery after the transfer was accurate, because the battery remaining power More, the smaller the charging current.
