## Features

- Super material: It is made of electronic accessories, nickel plating on surface(anti-oxidatioan), inner conductor: pure copper.it is long lasting and durable for you to use.
- Moreover. The buck module has 2 heat sinks that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current. With LED indicator, more stable and reliable to use.
- Input and output: With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. Output Current: 20A(max.), 15A (suggested). Efficiency: 97% (24V to 12V, 20A). Output Ripple: Less than equal 50mV. Designed with 75V/80A large current dual MOS tube.
- High Power High Efficiency: Adopting 75V / 80A large current dual MOS tube designed step-down board, Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a stable output. Large current 30A connection screw terminals, more convenient to install
- A wide range of applications: Widely uses in power transformer, DIY adjustable power supply, LED car display, mobile power, industrial equipment appliances, LED driver, monitor, solar energy, fan, battery conversions, micro-controllers, and electronic projects. so on. Maintain stable output voltage and limit the output current over a range of input voltages.
