Features With a wide input voltage range of 6V to 40V, the buck converter can accurately adjust output voltage and current Efficiency can be up to 96% measured at 20A converting 24V to 12V It is equipped with a 75V/80A large current dual MOS tube Input and output use high frequency electrolytic capacitor with low resistance, low ripple and stable output Wiring is convenient with these 30A large current screw terminals Features: With a wide input voltage range of 6V to 40V, the step-down converter can precisely adjust the output voltage current. Efficiency can be up to 96% measured at 20A converting 24V to 12V. It is equipped with a 75V/80A large current dual MOS tube. Input and output use high frequency electrolytic capacitor with low resistance, low ripple and stable output. Wiring is convenient with these 30A large current screw terminals. The buck module has 2 heatsinks which could improve heat dissipation. If there is a large difference between input and output voltage, please reduce power and current. Specifications: Input voltage: 6V to 40V DC (10V to 40V is recommended) Output voltage: 1.2V to 36VDC Output current: 20A (max.), 15A (recommended) Efficiency: 95% (24V to 12V, 20A) Output ripple: ≤50mV Wiring method: terminal Short circuit protection: self-recovery (cannot be short circuited for a long period of time) Size: 60 x 53 x 27mm/2.36 x 2.08 x 1.06" VO+ Positive output If the input and output are grounded together, the CV outputs a constant voltage when idle, the CC outputs a constant current VO- Output negative +IN Input positive -IN Negative input CV Setting the output voltage CC Setting the output current EN Enable, low voltage shutdown output; Suspension, high voltage level is effective Package Includes: 1 x Module Note: Please note that the new and old type of this product will be shipped randomly.
