Application range
1. Use as a normal buck module with overcurrent protection
Instructions:
(1) Press the right button to adjust the digital meter to the
[Display Output Voltage] interface, and adjust the “Constant Piezo
Transistor” to make the output voltage reach the desired voltage
value;
(2) Adjust the digital meter to the [display output current]
interface, directly short the output end of the module (find a
thick wire shorted to the output end), adjust the "constant current
potentiometer" to make the digital meter The current value reaches
the preset overcurrent protection value; (for example, if the
current value displayed by the onboard ammeter is 4A, then the
maximum current of the module is limited to 4A, and the red
indicator light is bright when the current reaches 4A)
(3) Connect the load and work.
2. Use as a battery charger
Modules without constant current function cannot be used to charge
the battery. Because the voltage difference between the battery and
the charger that consumes electricity is too large, the charging
current is too large, causing damage to the battery. Therefore, the
battery should be used at the beginning. Stream charging, when the
charging reaches a certain level, it automatically switches back to
constant voltage charging.
Instructions:
(1) Determine the float voltage and charge current of the battery;
(If the lithium battery parameter is 3.7V/2200mAh, then the float
voltage is 4.2V, and the maximum charge current is 1C, ie 2200mA)
(2) Under no-load conditions, adjust the digital meter of the
module to the [display output voltage] interface, and adjust the
"constant piezoelectric positioner" to make the output voltage
reach the float voltage;
(3) Adjust the digital meter to the [display output current]
interface, and directly short the output end of the module (find a
thick wire to short the output end), then adjust the "constant
current potentiometer" to make the digital meter The current value
reaches a preset charging current value;
(4) The charging lamp current defaults to 0.1 times the charging
current; (the battery is gradually reduced during the charging
process, gradually changing from constant current charging to
constant voltage charging, if the charging current is set to 1A,
then when When the charging current is less than 0.1A, the blue
light is off, the green light is on, and the battery is charged.
(5) Connect the battery and charge it.
(Steps 1, 2, 3, and 4 are: input terminal is connected to the power
supply, and the output terminal is not connected to the battery.)
3. As LED constant current drive module
(1) Determine the operating current and maximum operating voltage
at which you need to drive the LEDs;
(2) Under no-load conditions, adjust the digital meter to the
[display output voltage] interface, adjust the "constant
piezoelectric positioner" to make the output voltage reach the LED
working voltage;
(3) Adjust the digital meter to the [display output current]
interface, and directly short the output end of the module (find a
thick wire to short the output end), then adjust the "constant
current potentiometer" to make the digital meter The current value
reaches a preset LED operating current;
(4) Connect the LED and test the machine.
(Steps 1, 2, and 3 are: input power supply, output no load is not
connected to LED light)
