## Description

About us: 300W 20A DC Buck Module Constant Current Adjustable Step-Down Converter Voltage Output Current: 20A(max.), 15A (suggested) Output Voltage: 1.2V to 36V DC Efficiency: 95% (24V to 12V, 20A) With a wide input voltage range from 6V to 40V (10V to 40V is suggested), the step-down converter can accurately adjust output voltage and current Output Ripple: Less than equal 50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery (cannot short circuit for long time) VO+: Output positive VO-: Output negative +IN: Input positive -IN: Input negative CV: Output voltage adjustment CC: Output current adjustment EN: Enable, low voltage level shut off output; suspension, high voltage level is effective When input and output is common grounded, no-load CV output constant voltage, CC output constant current Working Tempreture: -10Celsius -75 Celsius Designed with 75V/80A large current dual MOS tube The buck module has 2 heat sink that could enhance heat dissipation Wiring is convenient with these large current 30A screw terminals Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output Stable and reliable Fine workmanship and durableWidely used in industrial Automation, scientific Research Equipment, LED Lighting, air Purification, civil equipment, solar panel voltage regulator, battery charging，wind turbines and so on Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. Package Included: 1PCS * High-power Buck Converter Step-down Module

Review: workes good like it
Review: This is easy to set up. You need to use a malty meter to check power and current. Set the power to the required voltage. Then set the current. All done. But Its worth noting that this needs to be a bit of a match to what you are using it for. For example if yo need 12 volts at 1 or amp or lower. Then it could be worth using a smaller buck converter. Above 1 amp it works ok. 2 and above more control. I'm not sure of the reliability as yet as I have not used it enough. Below 1 amp the current detection tends not to be too effective.

## 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.
- Package including: 1 Pack of Constant Current Voltage Step-up Module. Moreove. 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.

Just be sure that you don't limit the current when adjusting the voltage output (unless that's what you're going for)
