Module parameters
Module nature: synchronous rectification, non-isolated step-down constant current constant voltage module, CC CV charging module
Scope of application: high-power LED constant current drive, lithium battery charging (including ferroelectric), 4V, 6V, 12V, 14V, 24V battery charging, nickel-cadmium nickel-metal hydride battery (battery pack) charging, solar panels, wind generators
Input voltage: 6-40VDC
Output voltage: Continuously adjustable (1.2-35VDC) for a long time below 32V (applicable to applications where the input voltage is higher than the output voltage and cannot be boosted)
Output current: Maximum 20A, within 15A for a long time (the power tube temperature exceeds 65 degrees, please add a fan to dissipate heat, high voltage output, please use derating)
Current limit range: 0.2-20A (regulation) module, please add a fan if it exceeds 65 degrees.
Minimum pressure difference: 3V
Working frequency: 150KHZ
Conversion efficiency: up to about 96% , the efficiency is related to the pressure difference and the use environment
Output ripple: Ripple around 50mV (no noise) 20M bandwidth (for reference only) 24V input measured
Working temperature: -10°C to 75°C) (Please pay attention to the temperature of the power tube in actual use, and if the temperature is too high, please strengthen the heat dissipation or derate the use)
Potentiometer adjustment direction: clockwise (increase), counterclockwise (decrease)
Output short circuit protection: Yes (instantaneous protection) constant current (currently set constant current value can not be short-circuited for a long time)
Input reverse connection protection: None,
Output anti-backflow: None, for the load self-charged or inductive load requires an additional 2-pole tube!
Wiring mode: terminal block
Module size: 60*53*30MM
Output current adjustment method:
1. Adjust the CV potentiometer and set the output voltage to the voltage value you need according to your load requirements.
2. Set the CC potentiometer counterclockwise for about 30 turns (that is, set the output current to the minimum), connect the LED, and adjust the CC potentiometer to the current you need. For battery charging, after the battery is discharged, connect to the output and adjust CC to the current you need. (When charging, you must use the discharged battery to adjust, because the battery has more power More, the smaller the charging current.
