## Overview

The Constant Current CC CV Buck Converter Module is a high-performance power supply solution, capable of stepping down voltages from DC 6-40V to a customizable output of 1.2-36V. With a maximum output of 20A and 300W, this module is perfect for a variety of applications, including DIY projects, LED displays, and industrial equipment. Its impressive efficiency of up to 96% ensures minimal energy loss, while the dual MOS design and effective heat dissipation features guarantee reliability and longevity.

## Description

Product Description: Input Voltage: DC 6 - 40V Output Voltage: DC 1.2 - 35V (Continuously Adjustable) Output Current: Maximum 20A (Long Time Within 15A) Current Limit Range: 0.2 - 20A (Adjustable) Limit Low Voltage Difference: 3V Operating Frequency: 150KHz Conversion Efficiency: Maximum 96 Percent (The efficiency depends on the Voltage difference and the operating environment.) Output Ripple: about 50mV (Without Noise) Operating Temperature: -10 - +75 Degrees Celsius Potentiometer Adjustment Direction: Clockwise (Increase), Counterclockwise (Decrease) Output Short Circuit Protection: Yes Input Reverse Connection Protection: None Output Anti Back Flow: None Output current regulation method : - Adjust CV potentiometer, according to your load requirements, the output voltage set to the voltage value you need. - Counterclockwise CC potentiometer 30 circles, that is, the output current set to the limit of small, connected to the LED, CC potentiometer to the current you need. - For the battery charging, the battery after discharge, then received the output, adjust CC to the current you need, for charging must be used to discharge the battery adjustment is accurate, because the battery remaining in the more power, the smaller the charging current. Place of Application: - High power LED constant current drive. - Lithium Battery Charging (Including Iron Battery) - 4V, 6V, 12V, 14V, 24V Battery Charging - NiCd / NiMH Battery Charging - Solar Panels / Wind Generator Note: - The long-term working voltage is below 32V, which is applicable to the application where the input voltage is higher than the output voltage, and cannot be boosted. - If the temperature of the power tube exceeds 65 degrees celsius, please add a fan for heat dissipation. If the power tube has high voltage output, please derate it for use. Package Include: 1 x Power Supply Module

## Features

- The buck converter input voltage range is DC 6-40V 6 - 40V, adjustable output voltage range is DC 1.2 - 36V, can be used to convert 24V to 12V 5V, adjustable output current range is 0 - 20A, max output power is 300W.
- The step-down converter can accurately adjust output voltage and current. The efficiency can be up to 96 percent, (measured at 20A, converting 24V to 12V).
- It is designed with 85V 80A large current dual MOS. Input and output use high frequency low resistance electrolytic capacitor, low ripple, and gives a 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.
- Application: DIY stabilized voltage supply, LED car display, mobile power, LED driver, monitor, solar energy, fans, photovoltaic energy, motor, industrial equipment appliancesetc
