DC 10-50V Boost Voltage Constant Current 5A Power Supply Module DC-DC Battery

Description

DC 10-50V Boost Voltage Constant Current 5A Power Supply Module DC-DC Battery
Boost constant voltage constant current power supply module DCDC battery charging LCD display
5A boost module (constant voltage constant current LCD with crystal case)
1. Highlights
1.1. The button can completely shut down the output! Due to the special boost architecture, the output voltage is the input voltage after the traditional boost module is turned off. This product overcomes this problem.
1.2. Self-protection ability, the traditional boost module is easy to burn under the conditions of load start, setting output voltage lower than input voltage, output voltage regulation is too high, etc. This module overcomes these problems and adds more protection functions. . The input end anti-reverse protection, reverse connection will not burn; there is anti-backflow function, you can directly charge the battery; another over-power over-current and over-voltage protection.
1.3. Wide voltage range, up to 50V.
2. 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 needs to be increased)

3. Function description
3.1. Module has IN/OUT, ON/OFF two buttons: IN/OUT button switches input voltage and output voltage display, long press can switch output current output power display; ON/OFF button control output ON or OFF, each time The default output state is OFF.
3.2.CC potentiometer is used to set the 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; access the battery CHARGE indicator (red) Lights up, the FULL indicator (green) lights up when full; the right CV potentiometer is used to set the output voltage and rotate clockwise to increase the output voltage. The OUT indicator is an output status indicator that lights up when there is voltage at the output, otherwise it is off.
4. How to use
4.1. Use 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 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 potentiometer clockwise. Increase the limit current.
4.2. Use as a battery charger
A module without a constant current function cannot be used to charge a battery. Because the voltage difference between the battery and the charger that consumes electricity is large, the charging current is too large, causing damage to the battery. Therefore, the battery should be charged with constant current at the beginning, and automatically switched back to constant voltage charging when charging to a certain extent.
(1) Determine the floating charge voltage and charging current of the rechargeable battery you need, and adjust the output voltage to the charging voltage;
(2) First rotate the CC potentiometer counterclockwise for more than 20 turns, connect the battery, rotate the CC potentiometer clockwise, and gradually increase the charging current to the charging current you need.
5. Notes
5.1. Module input IN-disable and output OUT-short, otherwise the constant current function will be invalid.
5.2. Please ensure that the power of the power supply is greater than the power required by the output load. Please reduce the power usage when the module is hot!
5.3. Please read the product description carefully before using it. Damage caused by improper use will not be compensated.
5.4. It is not supported to adjust the constant current value by shorting the output voltage.
