Main highlights

With natural heat dissipation, the power must not exceed 400 W and the current 15 A. If the output voltage is high and the input output voltage difference is large, please reduce the current to be used.
This power supply is a downward power supply and the output voltage can only be lower than the input voltage. The efficiency depends on the input and output voltage, current and voltage difference.
The current detection of the module is a low-end detection. Please do not short the input negative pole and output negative pole directly with wires, as the current of the short circuit negative pole may not be constant, which may cause damage to the power supply and electrical equipment that requires constant current.
If the input voltage exceeds 36V, first set the ON/OFF switch to OFF, connect the cable and then set the switch to ON (to prevent ignition during wiring).
If the current exceeds 15A and the power exceeds 400W, please add a fan for heat dissipation.

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.)
