DC Adjustable LCD Display Step-down Power Supply Module 10A Adjustable Constant Current Constant Voltage Converter with Case

DC Adjustable LCD Display Step-down Power Supply Module 10A Adjustable Constant Current Constant Voltage Converter with Case Module parameters: Input voltage: 7V-36V Output voltage: 2V-32V continuously adjustable (can only be used as a buck module, the input must be greater than the output 1V) Output current: adjustable, maximum 10A (recommended to use within 8A, natural heat can be diated at room temperature below 5A or 70W, please strengthen heat diation when it is exceeded, it is recommended to add a small fan! Constant current requires output voltage above 2V to be adjustable, current adjustment, It will only work in the constant current state.) Output power: maximum 150W (recommended to use within 100W, please reduce the power when using large preure difference) Working temperature: -20 ~ +75 degrees (note the temperature of the power tube when using, if it exceeds, please strengthen the heat diation) Working frequency: 300KHz Conversion efficiency: 95% Short circuit protection: Yes, the constant current value currently set by constant current Input reverse connection protection: yes Output backflow: none Installation method: Acrylic board on both sides, 8 copper pillars, 8 3mm screws, reverse installation when keys are installed Wiring method: terminal or welding terminal, IN is input, OUT is output Module size: length 80mm width 53mm height 35mm Calibration method: This module is equped with a calibration function. You don't need to worry about the measurement inaccuracy. If you find that the display is inaccurate, you can use the following methods to calibrate it. Just use the calibration once for the first time! It is recommended to perform a calibration according to the following method! Voltage calibration: In the case of power off, pre and hold the "Set" on, power on, enter the voltage calibration mode, the LCD screen starts to flash, release the set on, pre the "Set" on for plus, "OK" for minus, calibration For the correct input terminal voltage, for example: the input voltage is 12.65V, then adjust the current voltage to 12.65V, automatically save after 2 seconds, the calibration is completed after power off and exit! Special note: It is reflected that the output voltage cannot be adjusted, because the default output voltage of the module is about 20V when it leaves the factory. When you encounter this problem, please turn the ADJ-V potentiometer counterclockwise for more than 10 turns until the voltage value changes, and then use the module to adjust the voltage normally. Setting instructions: The setting key can set the display mode, which is divided into three types: 1. F-0 mode: display output voltage; 2. F-1 mode: display input voltage; 3. F-2 mode: alternating display of input and output voltage; Instructions for use: Pre the "Set" on to cycle through the three display modes, the corresponding indicator will turn on or off, pre the "OK" on to save and exit, and pre the "OK" on to switch the backlight of the LCD screen. Application range: Note that the constant current adjustable current must be in the constant current mode only when the actual load output current is greater than the set current, otherwise it is working in a constant voltage state, not the current is adjusted to 2A, or any device is changed to 2A, also hope Know. The constant current of the output voltage above 2V will take effect! 1. Used as a common buck module with overcurrent protection capability Instructions: (1) Under no-load conditions, adjust the "constant voltage potentiometer ADJ-V" to make the output voltage reach the voltage value you want; (2) Directly short-circuit the output end of the module (just find a thick wire or tweezers to short-circuit the output end, note: do not adjust the voltage when short-circuiting), then adjust the "constant current potentiometer ADJ-I" so that The displayed current value reaches the preset overcurrent protection value; or the current can be adjusted by connecting the load. (For example, the current value displayed by the onboard ammeter is 4A, then the maximum current of the module is limited to 4A, and the constant current indicator red indicator lights when the current reaches 4A) (3) Connect the load and work. 2. Use as a battery charger Instructions: (1) Determine the float charge voltage and charge current of the battery; (If the lithium battery parameter is 3.7V/2200mAh, then the float charge voltage is 4.2V, and the maximum charge current is 1C, which is 2200mA) (2) Under no-load conditions, adjust the "constant voltage potentiometer ADJ-V" so that the output voltage reaches the float charge voltage; (3) Directly short-circuit the output end of the module (just find a thick wire or tweezers to short-circuit the output end, note: do not adjust the voltage when short-circuiting), then adjust the "constant current potentiometer ADJ-I" so that The display current value reaches the preset charging current value; or the current can be adjusted by connecting the load. (4) The charging lamp current defaults to 0.1 times the charging current; (The current of the battery gradually decreases during the charging proce, and gradually changes from constant current charging to constant voltage charging. If the charging current is set to 1A, then when When the charging current is le than 0.1A, the yellow indicator of the charging indicator is off and the blue indicator of the full indicator is on. At this time, the battery is fully charged), please disconnect the battery terminal before disconnecting the input terminal to prevent the battery Backflow damages the module! (5) Connect the battery and charge. 3. Used as a constant current LED drive module (1) Determine the working current and working voltage you need to drive the LED; (2) Under no-load conditions, adjust the "constant voltage potentiometer ADJ-V" so that the output voltage reaches the LED working voltage; (3) Directly short-circuit the output end of the module (just find a thick wire or tweezers to short-circuit the output end, note: do not adjust the voltage when short-circuiting), then adjust the "constant current potentiometer ADJ-I" so that The displayed current value reaches the preset LED working current; or the current can be adjusted by connecting the load. (4) Connect the LED and test the machine. Package included: 1 × DC Adjustable LCD Display Step-down Power Supply Module About shping
