New upgrade, 5A step-down constant voltage constant current
module, can charge battery, lithium battery, etc., with switching
lamp control, easy to observe the charging state. It can be used
as a high-power LED driver module with PWM control input
interface and switch control interface. It is convenient to use
single-chip computer to control driving current.

Method of setting voltage, current and switching light: (see illustration above)

Set the output voltage: According to the floating charge voltage of the battery

you want to charge, or the voltage of the series and parallel LED, adjust the
constant voltage potentiometer (CV), set the output voltage to the required voltage.
(without load)

Set the turn-lamp current indication: after setting the output voltage, adjust the

CC potentiometer counterclockwise by about 20 cycles, use the multimeter 20A
current-stop short-circuit output, adjust the CC potentiometer to the current you
need to turn-lamp, and then adjust the turn-lamp potentiometer (LED) to just turn
on the green light

Set the constant current value: After adjusting the lamp current, the multimeter
20A current gear still short-circuit output CC potentiometer to the current value you
need to set.

APPLICATION

© Module size: 60 mm long, 26 mm wide and 20 mm high

oO DIY is a regulated power supply with constant current function. It is
not afraid of short circuit in use, so it can protect the load.
Power your electronic equipment.

> Charge all kinds of batteries. Set charging voltage and current according
to different voltage and capacity of batteries. With charging indication
function, it is convenient to observe charging status.

© Charging all kinds of batteries by using solar panels with constant
current function can prevent overcharge of batteries and effectively
protect batteries.

© Drive high-power LED, can be combined freely in series and parallel,
with PWM control input, and can control the brightness of LED by single
chip computer (PWM control frequency range 100-300 Hz).

© As an on-board power supply for your mobile phone or various digital
products.
