Specification:

Module name: 400W boost constant current module
Module nature: non-isolated boost module (BOOST)
Input voltage: DC8.5V-50V
Input current: 15A (MAX) over 8A or module temperature over 65 degrees, please strengthen heat dissipation
Static working current: about 10mA (measured when 12V rises to 20V, the higher the output voltage, the higher the quiescent current will increase)
Output voltage: 10-60V continuously adjustable (suitable for applications where the input voltage is lower than the output voltage and cannot be stepped down.)
Output current: 12A MAX exceeds 7A or the module temperature exceeds 65 degrees, please strengthen heat dissipation (related to the input and output pressure difference, the greater the pressure difference, the smaller the output current)
Constant current range: 0.2-12A
Maximum output power: = input voltage*10A, such as: input 12V*5A=60W, input 24V*5A=120W,
Input 36V*5A=180W, input 48V*5A=240W,
Working frequency: 150KHz
Conversion efficiency: 96% typical (efficiency is related to input, output voltage, current, and pressure difference)
Overcurrent protection: Yes (when the input exceeds 15A, the output voltage will be automatically reduced with a certain range of error.)
Installation method: 4 2.5mm screw holes
Wiring mode: terminal block
Module size: length 67mm width 48mm height 28mm
 Module net weight: about 65 grams

Output voltage/current adjustment method:
1. Adjust the output voltage potentiometer (increase the voltage counterclockwise and decrease the voltage clockwise), according to your load requirements, set the output voltage to the voltage value you need. For example, the voltage of 10 LED strings is adjusted to 37V. (Turn the voltage up counterclockwise and turn down the voltage clockwise)
2. Adjust the output current potentiometer clockwise about 30 turns, set the output current to the minimum, connect the LED, and adjust the current potentiometer to the current you need. For battery charging, after the battery is discharged, it is connected to the output to adjust the current. (When used for charging, the discharged battery must be used for adjustment, because the more battery remaining in the battery, the lower the charging current .) (turn down clockwise current, turn up anticlockwise current)

Note:
Please do not use short circuit to adjust the current. The circuit structure of the boost module cannot be adjusted by short circuit.

Application range:

1. DIY a regulated power supply, input 12V, output can be adjusted from 12-50V.
2. To supply power to your electronic equipment, you can set the output value according to your system voltage.
3. As a vehicle power supply, it can supply power to your laptop, PDA or various digital products.
4. DIY a high-power notebook mobile power supply: equipped with a large-capacity 12V lithium battery pack, so that your books can be bright wherever you go.
5. The solar panel voltage stabilizes.
6. Charging batteries, lithium batteries, etc.
7. Drive high-power LED lights.

Package included:

3 x Power Supply Module
