Equipped with constant current output function, which can maintain the stability of output current, suitable for applications requiring constant current. 4. Support 25A continuous current output to ensure stable operation under high loads. 5. Able to provide output high power, suitable for applications requiring high energy supply, such as industrial equipment, power tools, laboratory equipment, etc. Parameter: Module name: 800W buck constant current module/1200W buck constant current module Module nature: non-isolated buck module Module nature: non-isolated buck module (BUCK) Input voltage: 15-90V Output voltage range: 2.5-72V (must meet the buck conditions, IN input multiplied by 0.8 equals the maximum output voltage) Output minimum voltage: 2.5V Output maximum voltage: 72V (input 90V voltage) input voltage * 0.8 is equal to the output voltage (for example, input is 40V, 40V * 0.8 = 32V 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 (working environment must be well ventilated) Continuously rated power: 700W/1000W (ventilated environment) Continuous working rated current: 25A/40A (under ventilated environment) Maximum output current: 28A/50A Heat dissipation mode: air-cooled heat dissipation Input anti-reverse connection: No (strictly prohibit input reversal) Input under-voltage protection: No Input over-voltage protection: No (prohibit over-voltage) Operating temperature: -10~+65 degrees Operating frequency: 80KHz Conversion efficiency: up to 97% (efficiency and input and output voltage, current, pressure difference) Short circuit protection: Yes (constant current protection) Heat dissipation mode: air-cooled cooling (temperature-controlled fan, open around 45 degrees) Output anti-return irrigation: No (charging the battery, the output connected to inductive loads, such as connected to the motor must be added to prevent reverse irrigation diode) Voltage and current adjustment method: (using tools multimeter, a screwdriver) Voltage adjustment: according to their own required voltage rotating power board “CV” blue potentiometer, clockwise voltage up, counterclockwise down the output voltage. The maximum output voltage is about 20% lower than the input voltage Output current adjustment: multimeter or ammeter to 50A20A or 10A current gear, the power supply voltage to 5V, constant current potentiometer “CC” counterclockwise about 10 turns, the current is adjusted to the minimum with a multimeter short-circuit output, and then clockwise adjustment of “CC “potentiometer to adjust the current to the required current value, (Note: constant current potentiometer “CC” counterclockwise turn 10 turns, the power supply may not have an output voltage, this is because the current is adjusted to 0 A.) Don’t worry about it, adjust the current clockwise and there will be output.)
