5A 90W boost constant current constant voltage power supply module DC converter 9-45V To 11-50V step up module board

Product parameters: Input voltage: 9-45V (When the input current is large, pay attention to the partial voltage on the input power line) Output voltage: 11-50V, the factory default output is about 15V (the input voltage is higher than the output voltage, the ERR interface will be displayed, and the output voltage will be increased) Output current: maximum 5A (le than 90W), output higher than 5A or 90W, automatic protection. Output power: natural heat diation 90W (within 5A) Voltage display: resolution 0.05V, range 0-50V, actual error ± 0.3V (for customers with strict precision requirements) Current display: resolution 0.005A, range 0-5A, actual error ± 0.1A (for customers with strict precision requirements) Working current: about 30mA Input reverse connection protection: Yes Output end anti-backflow: Yes Short circuit protection: Yes Size: length * width * height 82 * 52 * 41mm Weight: 93g 1. The module has IN/OUT, ON/OFF two ons: IN/OUT on switches input voltage and output voltage display, long pre can switch output current output power display; ON/OFF on control output is ON or OFF, each time The default output state is OFF. 2.CC sets the potentiometer for charging current, clockwise rotation, can increase the charging current, the current value setting needs to be set after the battery is connected, can not directly short the output setting; CHARGE charging indicator when the battery is charging (red ) Lights up, when full, the FULL full indicator (green) lights up; the right CV sets the potentiometer for voltage, and rotates clockwise to increase the output voltage. The OUT indicator is the output status indicator. It is on when there is voltage at the output, otherwise it is off. 4.1. It is used as a normal boost module with overcurrent protection. (1) Adjust the CV constant voltage device so that the output voltage reaches the voltage you want. (2) Adjust the CC current adjustment potentiometer for more than 20 turns. Adjust the CC constant current potentiometer clockwise to make the output current reach the overcurrent protection value you want to set. If the ERR interface is displayed after the load is connected, then adjust the CC clockwise. The potentiometer increases the current limit. 3. 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. (1) Determine the floating charge voltage and charging current of the you need, and adjust the output voltage to the charging voltage; (2) Firstly rotate the CC current adjustment potentiometer counterclockwise for more than 20 turns, connect the battery, rotate the CC current potentiometer clockwise, and gradually increase the charging current to the charging current you need. 4. 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) Adjusting the CV constant voltage device to make the output voltage reach the maximum working voltage of the LED; (3) Firstly rotate the CC current adjustment potentiometer counterclockwise for more than 20 turns, connect the LED load, adjust the CC constant current potentiometer clockwise to make the output current reach the predetermined LED working current.
