HZDZ 5A Constant Current / Voltage LED Driver Battery Charging Module
Input voltage range:6~38VDC(Note:input voltage not exceeding 38V); Output voltage range:1.25-36VDC adjustable; Output current:0-5A; Output power: 75W; High efficiency up to 96%; Built in thermal shutdown function; Built in current limit function; Built in output short protection function; Input reverse polarity protection: None (if required£¬ high current diode in series with the input). 1Use as a step-down modules with overcurrent protection capabilities Usage: (1) adjust the voltage potentiometer so that the output voltage reaches the value you want. (2) use a multimeter to measure the output short-circuit current with10A stalls£¬ while regulating the current potentiometer so that the output current reaches a predetermined overcurrent protection value. (3)Connected to the load. 2Use as a battery charger Usage: (1) Make sure you need to charge the battery float voltage and chargingcurrent; (if lithium parameters 3.7V/2200mAh£¬ then the float voltage is 4.2V£¬ the maximum charging current 1C£¬ie 2200mA) (2) Under no-load conditions£¬ adjust the Voltage potentiometer so that the output voltage reaches the float voltage; (if to 3.7V rechargeable lithium battery£¬ the output voltage can be adjusted to 4.2V) (3) use a multimeter to measure the output short-circuit current with10A stalls£¬ while regulating the current potentiometer so that the output current reaches a predetermined Charging current value. (4) Charge turn lamp current factory default is 0.1 times the charging current;(Battery during charging current is gradually reduced£¬ if the charge current setting is 1A£¬ then when the charge current is less than 0.1A£¬ blue lights turned off£¬ the green light is on£¬ which means that the battery is fullycharged) (5) connected to the battery charge. (1£¬2£¬3£¬4 steps as: Output is unloaded£¬ do not connect the battery) 3Use as a LED constant current driver module Usage: (1) adjust the voltage potentiometer so that the output voltage reaches the value you want. (2) use a multimeter to measure the output short-circuit current with 10A stalls£¬ while regulating the current potentiometer so that the output current reaches a predetermined LED operating current. (3) Connect LED£¬ work. (1£¬2 steps as: Output is unloaded£¬ do not connect LED)
