Features: The input voltage of the converter is DC 6-40V, adjustable output voltage is DC 1.2-36V, can be used to convert 24v to 12v 5v, adjustable output current is 0-20A, max power is 300W. The step-down regulator can be applied to constant output current. With a wide input voltage - from 6V to 40V - the step-down converter can adjust the output voltage and current precisely. The efficiency can be up to 95% (measured at 20A, converting 24V to 12V). Short circuit protection: Self-recovery (cannot short circuit for a long time). when input and output are common ground, no-load CV output constant voltage, CC output constant current Adopting 75V/80A large current dual MOS tube designed step-down board, input and output use high-frequency electrolytic capacitor with low resistance, low ripple, and provide stable output. Large 30A connection screw terminals, more convenient to install. Usage: DIY stabilized voltage supply, LED car display, power, industrial equipment, LED driver, solar energy, fans, photovoltaic energy, motor, etc. Specifications: Material: ABS Input Voltage: 6V to 40VDC (10V to 40V-suggested) Output Voltage: 1.2V to 36V DC Output Current: 20A (max.), 15A (suggested) Efficiency: 95% (24V to 12V, 20A) Output Ripple: ≤50 mV Note: Please allow 1mm error due to manual measurement.
