Use as a normal blood pressure modules with overcurrent protection capabilityInstructions:(1) constant pressure regulator potentiometer, the output voltage reaches the voltage value you want(2) 10A current with a multimeter measuring the output short circuit current file (directly to the two leads to the output can), while adjusting the constant current potentiometer allows the output current reaches a predetermined value of overcurrent protection. (Such as the current value of the multimeter displays 4A, then you can use the module to the maximum current 4A, 4A current to constant voltage constant current when the red light is on, otherwise the light off)Note: When used in this state, since the output of 0.05 ohm current sense resistor, there will be 0 ~ 0.3V voltage drop after connected to the load, this is normal! This drop is not being pulled down your load, but down-sampling resistor.2. Use as a battery chargerModule without constant function can not be used to charge the battery, since the end of the battery and charger power consumption big difference between charging current is too large, resulting in damage to the battery, so when you want to start the battery using a constant current charging, when charging to a certain extent automatically switches back to constant voltage charging.Instructions:(1) Make sure you need to recharge battery float voltage and charging current; (if lithium argument is 3.7V / 2200mAh, then float voltage is 4.2V, the maximum charging current 1C, namely 2200mA)(2) under no-load conditions, the multimeter to measure the output voltage of the constant voltage potentiometer to adjust the output voltage reaches the float voltage; (if rechargeable lithium battery to 3.7V, the output voltage can be adjusted to 4.2V)(3) 10A current with a multimeter measuring the output short circuit current file (directly to the two leads to the output can), while adjusting the constant current potentiometer allows the output current reaches a predetermined charge current value;(4) Charging turn lamp current default factory setting is 0.1 times the charging current; (the battery during charging current is gradually reduced, gradually converted to constant voltage charging by the constant current charging, if the charging current setting is 1A, then when Charge current is less than 0.1A when the blue light off, green light is on, then the battery is fully charged)(5) connected to the battery charge.(1,2,3,4 step is: input termination power, output unloaded battery is not connected)3. Use a high-power LED constant current driver module(1) determine the work you need to drive the LED current and the maximum operating voltage;(2) No-load condition, the multimeter to measure the output voltage of the constant voltage potentiometer to adjust the output voltage reaches the LED maximum working voltage;(3) 10A current with aXL4015-B：1.

There are two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in;4. When used as a lithium battery charger, you can set the float voltage and charge current.Is it charging or already full;5. With current limiting protection, the module will not burn out even if the output is short circuited. Module :Input voltage: 4-38VOutput voltage: 1.25-36V continuously adjustableOutput current: adjustable, up to 5AOutput power: up to 75WWorking temperature: -40~85 degreesWorking frequency: 180KHzConversion efficiency: up to 96 hundredShort circuit protection: Yes (limited current 8A)Over temperature protection: Yes (automatically turn off the output after over temperature)Input reverse connection protection: None, (If necessary, please input a large current diode in the input string)Installation method: 4 3mm silkWiring method: terminal block or soldering terminal, V-IN is input, V-OUT is outputModule size: length 61.7mm width 26.2mm height 15mmSecond, the scope of application1. Use as a normal buck module with overcurrent protectionInstructions:(1) Adjust the constant voltage positioner to make the output voltage reach the desired voltage value.(2) Use the multimeter 10A current file to measure the output short-circuit current (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer to make the output current reach the predetermined overcurrent protection value. (For example, if the current value displayed by the multimeter is 4A, then the maximum current can only reach 4A when you use the module, and the red constant voltage constant current indicator will be on when the current reaches 4A, otherwise the indicator will be off)Note: When using in this state, since the output has a current sampling resistor of 0.05 ohms, there will be a voltage drop of 0~0.3V after the load is connected. This is normal! This voltage drop is not pulled down by your load, but falls to the sampling resistor.2. Use as a battery chargerModules 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 rechargeable battery you need; (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, the multimeter measures the output voltage, and adjusts the constant voltage positioner to make the output voltage reach the float voltage; (If charging the 3.7V lithium battery, adjust the output voltage to 4.2V)(3) Use the multimeter 10A current file to measure the output short-circuit current (directly connect the two test leads to the output terminal), and adjust the constant current potentiometer to make the output current reach the predetermined 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 a high power 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, the multimeter measures the output voltage, and adjusts the constant voltage positioner to make the output voltage reach the maximum working voltage of the LED;(3) Measure the output short-circuit current with the multimeter 10A current file, and adjust the constant current potentiometer to make the output current reach the predetermined LED operating current;(4) Connect the LED and test the machine.(Steps 1, 2, and 3 are: input is connected to the power supply, and the output is not connected to the LED.)XL4015-C：Module Highlights: 5A High Power High Efficiency Low Ripple with Power Indicator Light Gives Heatsink! ! !Module performance and features:Module nature: non-isolated buck module (BUCK)Input voltage: 4-38V (Please try not to exceed 38V as input)Output voltage: 1.25-36V continuously adjustableOutput current: 0-5A, recommended for use within 4.5A.Output power: It is recommended to use within 75W.
