Description:
Wide voltage input 5-30V, wide voltage output 0.5-30V, both step-up and step-down, for example, you adjust the output voltage of 18V, then the input voltage between 5-30V casually change, will always output 18V; Enter 12V, adjust the potentiometer to set any output 0.5-30V。
High power, high efficiency, better performance than the XL6009 / LM2577 program. Using external 60V75A high-power MOS, high current parallel high-voltage diode SS56.
Sendust magnetic ring inductance, high efficiency. Constant current mode without inductive whistle.
You can set the current size, used to limit the output current, constant current drive, battery charging light occasions.
Own output anti-inadvertently function, do not have to add another anti-reflux diode when charging the battery.

Instructions:
1. As an over-current protection with the ability to use ordinary buck-boost module
Instructions:
(1) Adjust the CV constant voltage potentiometer so that the output voltage reaches the voltage you want
(2) Measure the output short-circuit current with 10A current meter (connect the two test leads directly to the output end), and adjust the CC constant current potentiometer to make the output current reach the preset over-current protection value. (For example, if the current value displayed by the multimeter is 2A, the maximum current will only reach 2A when you use the module. When the current reaches 2A, the red constant voltage and constant current LED is on, otherwise the LED is off)
Note: When used in this state, because the output has a current of 0.05 ohms sampling resistor, the load will be 0 ~ 0.3V after the pressure drop, this is normal! This voltage drop is not pulled down by your load, but dropped to the sampling resistor.
2. Used as a battery charger
Without constant current function of the module can not be used to charge the battery, due to the power of the battery and the charger pressure drop is large, resulting in charging current is too large, causing damage to the battery, so the beginning of the battery to use constant Flow charging, when the charge to a certain extent automatically switch back to constant voltage charging.
Instructions:
(1) Determine the float voltage and charging current for which you need the rechargeable battery (if the lithium battery parameter is 3.7V / 2200mAh then the float voltage is 4.2V and the maximum charging current is 1C, ie 2200mA)
(2) Under no-load condition, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the float voltage. (If the 3.7V lithium battery is charged, adjust the output voltage to 4.2V)
(3) Measure the output short-circuit current with 10A current meter (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer so that the output current reaches the predetermined charge current value;
(4) The default charge current of charging turn-on lamp is 0.1 times of the charging current. (The current of the battery is gradually decreased during the charging, and it is gradually changed from constant current charging to constant voltage charging. If the charging current is set to 1A, Charge current is less than 0.1A, the blue light is off, the green light is on, when the battery is charged)
(5) Connect the battery, charging.
(Steps 1, 2, 3 and 4 are as follows: the input termination power, the output is not connected to the battery load)
3. As a high-power LED constant current driver module
(1) Make sure you need to drive the LED operating current and the maximum operating voltage;
(2) Under no-load conditions, the multimeter measures the output voltage and adjusts the constant voltage potentiometer so that the output voltage reaches the maximum operating voltage of the LED.
(3) with a multimeter 10A current measurement output short-circuit current, while adjusting the constant current potentiometer so that the output current reaches the predetermined LED operating current;
(4) connected to the LED, test machine.
(Steps 1, 2, and 3 are as follows: Input the power and output the no-load LED.)
Note: This module is more than 3A, 35W use, please strengthen the heat! dissipation! !
Precautions:
1. The module input IN- is forbidden to be shorted to the output OUT-, otherwise the constant current function is invalid.
2. Make sure the power of the power supply is greater than the power required by the output load!
3. Module input without anti-reverse input function, please pay attention to the positive and negative power supply direction.
4. If the module is full load, the input voltage should be over 8V. When the input voltage is 5V, the output power is about 15W. Module current value 4A, the premise subject to the maximum output power, such as the output 17V, the current should not exceed 2A.
5. The module with output short circuit protection, short circuit protection module automatically shut down the output, the module can be restored on the power, if your power supply without output current limiting protection, it is recommended that the module input front-end fuse in series to increase the safety factor.
6. The module has input under-voltage protection function, the default is about 4.2V, below this value, it will automatically disconnect the output power to the module can be restored (Note that the voltage at the module port, when the input current is relatively large Do not ignore the partial pressure on the input wire).
7. The module contains three indicator lights, constant voltage and constant current status indication (red, constant current mode is on), charging indicator (blue), full indication (green, turn light current size set current 1/10) .
