Note for use: After connecting to the power supply, remember to rotate counterclockwise to rise! If the rotation is wrong, you need to turn the number of turns in the opposite direction to disappear to trigger the rising voltage!
Module name: 400W boost constant current module
Module nature: non-isolated booster module (BOOST)
Input voltage: DC8.5V-50V
Input current: 15A (MAX) more than 8A or module temperature more than 65 ℃, please strengthen heat dissipation
Static working current: about 10mA (measured when 12V rises to 20V, the higher the output voltage, the higher the static 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 reduced.)
Output current: 12A MAX is more than 7A or module temperature is more than 65 ℃, please strengthen heat dissipation (related to input and output differential pressure, the larger the differential pressure, 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: up to 96% (efficiency is related to input and output voltage, current and voltage difference)
Overcurrent protection: Yes (if the input exceeds 15A, the output voltage will be automatically reduced, with a certain range error.)
Input reverse connection protection: none, (please input diode in series if necessary)
Installation method: 4 2.5mm screw holes
Wiring mode: wiring terminal
Output anti-backflow protection: none; If it is used for charging or the load has its own power, it needs to add a bipolar tube
Module size: length 67mm, width 48mm, height 28mm
Output voltage/current regulation method:
1. Adjust the output voltage potentiometer (increase the voltage counterclockwise and decrease the voltage clockwise), and set the output voltage to the voltage value you need according to your load requirements. For example, the voltage of 10 LED strings is adjusted to 37 V. (Turn up the reverse clock voltage and turn down the clockwise clock voltage)
2. Turn the output current potentiometer clockwise for 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, connect it to the output and adjust the current. (For charging, it must be adjusted with the discharged battery, because the more the battery remains, the lower the charging current.)
Please do not adjust the current by short circuit. The circuit structure of the boost module cannot be adjusted by short circuit.
