With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust the output voltage and current. The efficiency can be up to 95% (measured at 20A, conversion from 24V to 12V).
The input voltage range of the Aceirmc step-down converter is DC 6-40V, the adjustable output voltage range is DC 1.2-36V, can be used to convert 24V to 12V 5V, the adjustable output current range is 0-20A, the maximum output power is 300W. The down regulator can be set to constant output current
Short circuit protection: self-recovery (cannot be short-circuited for long time). Plus when input and output are grounded together, CV output constant without load, constant CC output current
Application: DIY stabilized power supply, LED car display, mobile power supply, industrial equipment, LED driver, monitor, solar energy, fan, photovoltaic, motor, etc
Adopting 75V/80A double MOS tubes with large current, designed step-down board, input and output use a high-frequency electrolytic capacitor with low resistance, low ripple and ensure a stable output. Large power connection screw terminals with 30A, more convenient to install

Output voltage: DC 1.5 V to 35 V voltage is infinitely adjustable, the maximum output current is 3A.
Mini size: 45 x 23 x 14 mm (with potentiometer). 6 pieces included.
Input voltage: DC 3 V to 40 V (input voltage must be 1.5 V higher than the output voltage, no increase).
High precision: The step-down converter is made of 36u thickened circuit boards, a high quality inductance with output LED display and superior semiconductor capacitors that can effectively filter out high-frequency noise. Suitable for various electronic projects.
Easy for DIY enthusiasts. Connect the device to the power source with a mini screwdriver to increase or decrease the output voltage by adjusting the screw on the blue potentiometer and monitoring the voltage with the multimeter to get the required voltage. (The factory default setting is high voltage. You need to counteract about 7-15 circles before the voltage drops. 1 circle means +/- 1V.)
