## Overview

The Aceirmc 3pcs 20A 300W CC CV Step Down Module is a versatile voltage regulator designed for a wide range of applications. With an input voltage range of DC 6-40V and an adjustable output voltage of DC 1.2-36V, this module ensures high efficiency and robust performance, making it ideal for DIY projects, industrial equipment, and more.

## Description

Features: With a wide input voltage range from 6V to 40V, the step-down converter can accurately adjust output voltage and current. The efficiency can be up to 96%, measured at 20A, converting 24V to 12V. It is designed with 75V/80A large current dual MOS tube. Input and output use high frequency low resistance electrolytic capacitor, low ripple, stable output. Wiring is convenient with these large current 30A screw terminals. The buck module has 2 heat sink that could enhance heat dissipation. When there is a big difference between input and output voltage, please decrease power and current.Specifications: Input Voltage: 6V to 40V DC(10V to 40V is suggested) Output Voltage: 1.2V to 36V DC Output Current: 20A(max.), 15A(suggested) Efficiency: 95%(24V to 12V, 20A) Output Ripple: ≤50mV Wiring Method: Terminal Short Circuit Protection: Self-recovery(cannot short circuit for long time) Size: 60 x 53 x 27mm / 2.36 x 2.08 x 1.06" VO+: Output positiveVO-: Output negative+IN: Input positive -IN: Input negativeCV: Output voltage adjustmentCC: Output current adjustmentEN: Enable, low voltage level shut off output; suspension, high voltage level is effectiveWhen input and output is common grounded, no-load CV output constant voltage,CC output constant currentPackage includes: 3 * 20A 300W DC DC Buck Converter

## Features
