Application

1.Use 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 with 10A
stalls, while regulating the “current potentiometer” so that the output
current reaches a predetermined overcurrent protection value. (For
example, the meter displays the current value of 4A, then you can use
the module to a maximum current of 4A)

(3) Connected to the load.

2.Use as a battery charger

Usage:

(1)   Make
sure you need to charge the battery float voltage and charging current;
(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 with 10A
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 fully   charged)

(5)   connected to the battery charge.

(1,2,3,4 steps as: Output is unloaded, do not connect the battery)

3.Use 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.

(in steps 1,2 do not connect LED)
