Parameter
Module name: 800W 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
Maximum output power: 800W
Continuously rated power: 700W
Continuous working rated current: 25A
Maximum output current: 28A
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.)
