Module name: 800W step-down constant current module/1200W step-down constant current module
Module nature: non-isolated step-down module
Module nature: non-isolated step-down module (BUCK)
Input voltage: 15-90V
Output voltage range: 2.5-72V (must meet the step-down conditions, IN input multiplied by 0.8 equals the maximum output voltage)
Output minimum voltage: 2.5V
Output maximum voltage: 72V (when input voltage is 90V) Input voltage*0.8 equals output voltage (for example, if the input is 40V, 40V*0.8=32V, the maximum output voltage is 32V. Input 90V*0.8=72V)
Output constant current : 800W: 1.5-28A continuously adjustable / 1200W: 2-50A continuously adjustable
Maximum output power: 800W/1200W (the working environment must be well ventilated)
Continuous working rated power: 700W/1000W (in a ventilated environment)
Continuous working rated current: 25A/40A (in a ventilated environment)
Maximum output current: 28A/50A
Cooling method: air cooling
Input reverse connection protection: no (reverse input connection is strictly prohibited)
Input undervoltage protection: no
Input overvoltage protection: no (overvoltage is prohibited)
Working temperature: -10~+65 degrees
Operating frequency: 80KHz
Conversion efficiency: up to 97% (efficiency is related to input and output voltage, current, and pressure difference)
Short circuit protection: Yes (constant current protection)
Cooling method: air cooling (temperature-controlled fan, turned on at about 45 degrees)
Output anti-reverse feeding: No (to charge the battery, the output is connected to an inductive load, such as a motor, an anti-reverse feeding diode must be added)

Voltage and current adjustment method: (using tools such as a multimeter and a flat-blade screwdriver)
Voltage adjustment: Rotate the "CV" blue potentiometer on the power board according to the voltage you need, turn the voltage clockwise to increase, and turn the output voltage counterclockwise to decrease. The maximum output voltage is about 20% lower than the input voltage.

Output current adjustment: Set the multimeter or ammeter to 50A, 20A or 10A current gear, adjust the voltage of this power supply to 5V, turn the constant current potentiometer "CC" counterclockwise for about 10 turns, adjust the current to the minimum, use the multimeter to short-circuit the output, and then adjust the "CC" potentiometer clockwise to adjust the current to the required current value. (Note: When the constant current potentiometer "CC" turns counterclockwise for 10 turns, the power supply may have no output voltage. This is because the current is adjusted to 0A. Don't worry about it. Adjust the current clockwise to increase the current and there will be output.)
