3. Function description:
3.1. There are two keys on the left side of the module: on/OFF: in/out button to switch input voltage and output voltage display. Long press can switch output current output power display;You can set the default output state of the next power to be on or off.
There is a module on the right side+,-Two buttons: + button press and increase the output voltage by 0.05V. Press and increase the continuous slow step by 0.1V and 1V. Press and increase the continuous slow step by 0.1V. Press and increase the continuous slow step by 0.05V. Press and decrease the continuous slow step by 0.1V. Press and decrease the continuous slow step by 0.1V.
3.2.Adj-I is to set the potentiometer at the current, which can be rotated clockwise to increase the set current. When the load current reaches the set current, enter the constant current state, and the CC constant current indicator (red) lights up.The OUT indicator is the output status indicator. When the output end has voltage, it will be turned on; otherwise it will be destroyed; the Char indicator lights are the charging indicator. When charging, the full indicator is full.When the current reaches 0.2A, the light is turned, the full indicator light is on, and the chan indicator is destroyed.
4. How to use:
4.1. As a normal antihypertensive module with overcurrent protection capabilities
(1) Press the button to set the output voltage to reach the voltage value you want.
(2) First rotate the ADJ-I current adjustment potentiometer counterclockwise to the end, then use the multimeter 10A current level to measure the output short circuit current (just connect the two meter pens to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise to make the output current reach the overcurrent protection value you want to set.(For example, the current value displayed by the multimeter is 2A, then the maximum current can only reach 2A when you use the module. When the current reaches 2A, the red constant current indicator light will turn on, otherwise the indicator light will turn off)
4.2. Use as a battery charger
The module without constant current function cannot be used to charge the battery. Because the battery consumed by the battery and the charger is very large, the charging current is too large and the battery is damaged.Flow charging, automatically switch back to constant voltage charging when charging to a certain degree.
(1) Determine the floating charging voltage and charging current of the battery you need to charge; (If the lithium battery parameter is 3.7V/2200mAh, then the floating charging voltage is 4.2V, and the maximum charging current is 1C, that is, 2200mA)
(2) Under no load conditions, the output voltage of the button reaches the floating charging voltage; (If you charge a 3.7V lithium battery, just adjust the output voltage to 4.2V)
(3) First rotate the ADJ-I current adjustment potentiometer counterclockwise to the end, then use the multimeter 10A current level to measure the output short-circuit current (just connect the two meter pens to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise to make the output current reach the predetermined charging current value;
(4) Connect the battery and charge it.
(Setting steps1, 2, 3: The output end is no load and the battery is not connected)
4.3. Use as a high -power LED constant current driver module
(1) Determine the operating current and maximum operating voltage you need to drive the LED;
(2) Under no load condition, press the button to set the output voltage to reach the maximum working voltage of the LED;
(3) First rotate the ADJ-I current adjustment potentiometer counterclockwise to the end, then use the multimeter 10A current level to measure the output short-circuit current (just connect the two meter pens to the output terminal), and adjust the ADJ-I constant current potentiometer clockwise to make the output current reach the predetermined LED working current;
(4) Connect the LED and test the machine.
(Setting steps1, 2, 3: The output is no load and does not connect to LED lights.)
5. Note:
5.1. The module input IN-forbidden to output OUT-short connection, otherwise the constant current function will fail.
5.2. Please ensure that the power supply power supply is greater than the power required for the output load. When the module is hot, please reduce the power use!
5.3. Please read the description of the product carefully before use. The damage caused by improper use will not be compensated.
