Product parameters:

Module name: 800W step-down constant current module

Module nature: Non isolated voltage reduction module

Module nature: Non isolated voltage reduction module (BUCK)

Input voltage: 15-90V

Output voltage range: 2.5-72V (must meet the voltage reduction condition, IN input multiplied by 0.8 equals the highest output voltage)

Minimum output voltage: 2.5V

Maximum output voltage: 72V (when input voltage is 90V) Input voltage 0.8 is equal to 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

Maximum output power: 800W (the working environment must be well ventilated)

Continuous working rated power: 700W (in ventilated environment)

Continuous working rated current: 25A (in ventilated environment)

Maximum output current: 28A

Heat dissipation method: air-cooled heat dissipation

Input anti reverse connection: None (input reverse connection is strictly prohibited)

Input undervoltage protection: None

Input overvoltage protection: None (overvoltage prohibited)

Working temperature: -10~+65 degrees Celsius

Operating frequency: 80KHz

Conversion efficiency: up to 97% (efficiency is related to input and output voltage, current, and voltage difference)

Short circuit protection: Yes (constant current protection)

Cooling method: Air cooling (temperature controlled fan, turned on at around 45 degrees)

Output anti backflow: None (to charge the battery, output to inductive load, such as connecting to a motor, anti backflow diode must be added)

Voltage and current regulation method: (using tools such as a multimeter and a Phillips screwdriver)

Voltage regulation: Rotate the "CV" blue potentiometer on the power board according to your desired voltage, increase the voltage clockwise and decrease the output voltage counterclockwise. The maximum output voltage is about 20% lower than the input voltage

Output current adjustment: Set the multimeter or ammeter to the current range of 50A 20A or 10A, adjust the voltage of the power supply to 5V, turn the constant current potentiometer "CC" counterclockwise for about 10 turns, adjust the current to the minimum, short-circuit the output with the multimeter, and then adjust the "CC" potentiometer clockwise to adjust the current to the desired value. (Note: When the constant current potentiometer "CC" is turned counterclockwise for 10 turns, the power supply may not have output voltage because the current is set to 0A. Don't worry about it, increase the current clockwise to output.)
