10A Adjustable Voltage Regulator with DC-DC Display
It is an adjustable DC-DC voltage reducer module with LCD display that can display voltage and current at the same time. This module can adjust both output current and output voltage.
Calibration method
Voltage calibration: When the power is off, press and hold the "SET" button, power on, enter voltage calibration mode, LCD display starts flashing, release the "SET" button. To adjust the settings, press the "ENT" button to decrease the voltage and the "SET" button to increase it. For example: if the input voltage is 12.65V, the voltage will be adjusted to 12.65V, automatic calibration will be completed after 2 seconds.
Special Note: If the first use of the output voltage cannot be adjusted, because the module is factory The default output voltage is 20V or so. When you encounter this problem, please rotate the ADJ-V potentiometer counterclockwise for more than 10 turns until the voltage value changes.
Technical Specifications
- Input voltage: 7V-36V
- Output voltage: 1.5-35V continuously adjustable
- Output current: Adjustable, maximum 10A (below 8A, 5A or 70W at normal temperature recommended to use, when exceeded, please strengthen the cooling! Add a small fan!)
- Output power: 150W maximum (recommended to use within 100W)
- Operating temperature: -20 to +75 degrees (Extreme please strengthen the cooling when)
- Working frequency: 300KHz
- Conversion efficiency: up to 95%
- Short circuit protection: Yes, constant current, constant current value sets the current
- Input reverse protection: No, if necessary, add a diode by yourself!
- Feedback output: No, for charging, if necessary, please add a diode by yourself add!
- Wiring: Terminals or solder terminals, IN for input, OUT for output
Display Setting description
Setting the display type is divided into three types
- F-0 mode: Displays the output voltage
- F-1 mode: Displays the input voltage
- F- 2 modes: Alternating display input and output voltage
Press "SET" key to show three display modes. The corresponding LED will be on or off. Press the "OK" button to save and exit. Press "OK" to change the LCD backlight.
Application Fields
Used as an ordinary step-down module with overcurrent protection
- In the no-load state, adjust the "ADJ-V" value of the constant voltage potentiometer to make the output voltage reach your desired voltage value< /li>
- Direct short circuit module output, then adjust the "constant current potentiometer ADJ-I" so that the current value reaches the preset value overcurrent protection value; or you can also adjust the current depending on the load.
- You can connect it to the load
Used as a battery charger
- Battery determine the charging voltage and charging current
- Under load conditions, adjust the "constant voltage potentiometer ADJ-V" so that the output voltage reaches the charging voltage;
- Direct short circuit module output, then " constant current potentiometer ADJ-I" to adjust the preset value of the charging current; or you can also adjust the current depending on the load.
- Charging turn lights available factory default 0.1 times charging current; (During battery charging, the battery gradually decreases and gradually decreases from constant current charging to constant voltage charging, if the charging current is set to 1A, then when the charging current is lower than 0.1A, the charging yellow indicator light is off, if the full blue light is on, then battery charging is completed), when charging is completed, please disconnect the battery terminal, then disconnect the input to prevent battery backflow from damaging the module!
- You can connect your battery to charge.
