Mô tả :
Module properties:
non-isolated regulated input voltage: 10.5-70VDC Please derate when the power supply voltage is lower than 12V
Input current: 10A max long time 8A max
Output voltage: 5-58VDC self-adaptive applications where the input voltage is higher or lower than the set output voltage
Output current: 8A max 6A max for a long time (cannot let the input and output current work at the maximum value, the sum of input and output current cannot exceed 12A)
Constant current adjustable: 0.5-8A
Output power: 180W max, maximum current 8A when working at low voltage, bare board without auxiliary heat dissipation, maximum output 30W, with heat sink without fan, maximum output 50W, when the module temperature exceeds 65 degrees, heat dissipation needs to be enhanced
Standby current: about 20ma
Conversion efficiency: about 90%
Input anti-reverse connection: no, please confirm the positive and negative before power on
Features
High thermal conductivity aluminum substrate design, convenient for external heat sink.
Ultra-wide input range, capable of boosting, bucking, and stabilizing.
Realize zero pressure difference between input and output, and the output voltage is adjustable.
Output voltage/current regulation method
1. Adjust the constant voltage adjustable potentiometer (clockwise to decrease the voltage, counterclockwise to increase the voltage), according to your load requirements, set the output voltage to the voltage value you need. For example, the voltage of 10 strings of LEDs is adjusted to 37V.
2. Adjust the constant current adjustable potentiometer clockwise for about 20 turns, set the output current to the minimum, connect the LED, and adjust the constant current adjustable potentiometer to the current you need. For battery charging, after the battery is fully discharged, it is connected to the output and adjusted to the current you need. , the charging current is smaller.)
Notice
Please do not adjust the current by short circuit, the circuit structure of this buck-boost module cannot be adjusted by short circuit.
