Module parameters:
Module nature: non-isolated voltage regulator
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
Applications where the adaptive input voltage is higher or lower than the set output voltage
Output current: 8A max, long time 6A max, do not allow the input and output current to work at the maximum value, and the sum of input and output currents cannot exceed 12A
Constant current adjustable: 0.5-8A
Output power: 180W max when working at low voltage, the maximum current is 8A, the bare board has no auxiliary heat dissipation, the maximum output is 30W, with a heat sink and no fan, the maximum output is 50W, when the module temperature exceeds 65 degrees, heat dissipation is required.
Standby current: about 20ma
Conversion efficiency: about 90%
Input anti-reverse connection: None, please confirm the positive and negative before powering on
Dimensions: 70*52*21MM (bare board)
70*52*46MM (with heat sink and fan)
Features:
1.Use high thermal conductivity aluminum substrate to adjust the meter, convenient for external radiator.
2.Input ultra-wide range, capable of boosting, stepping down, and stabilizing
3.Achieve 0 input and output voltage difference, adjustable output voltage
Output voltage/current adjustment method:
1. Adjust the constant voltage adjustable potentiometer (decrease the voltage clockwise, increase the voltage counterclockwise), 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.
2. Adjust the constant current adjustable potentiometer clockwise 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 discharged, connect to the output and adjust to the current you need. (When used for charging, you must use the discharged battery to adjust it, because the more the battery is left , The smaller the charging current.)
Please do not adjust the current in a short-circuit mode. The circuit structure of this buck-boost module cannot be adjusted in a short-circuit mode.
