## Overview

The DZS Elec 12A DC-DC Step Down Buck Converter is a compact, high-efficiency voltage regulator designed for professional and DIY applications. It supports a wide input voltage range (4.5V-30V) and offers a continuously adjustable output voltage from 0.8V to 30V with up to 12A current capacity. Featuring a durable aluminum heat sink, short-circuit and over-temperature protections, and a high switching frequency of 300KHz, this module delivers stable, low-ripple power ideal for vehicular, industrial, and electronic projects.

## Description

Feature: Module Name: 12A DC Step Down Buck Converter Module Type: Non-isolated step-down module Module Size: 60*51*22mm Input Voltage: 4.5V-30V Output Voltage: 0.8V-30V ( continuously adjustable ) Output Current: 0A-12A 100W ( Can be up to 200W if enhance heat dissipation ) Work Temperature: -40 degree to + 80 degree Switching Frequency: 300KHz Transfer Efficiency: 95% (MAX) Short-circuit Protection: Yes (Limited current 14A) Over-temperature Protection: Yes (Automatically shut off the output once over temperature) Reverse Voltage Protection: NO ( If need, please add large current tube.) Connection Mode: Terminals or solder terminals. V-IN for input, V-OUT for output The module has enhanced aluminum radiator and TVS tube, which make sure the work temperature be lower and safer. 50V/MLCC chip capacitor, combined with high frequency low resistance electrolytic condenser, make the output ripple lower. Suitable for DIY of storage battery, power transformers, adjustable voltage regulator, 24V power supply, LED lights power supplies, industrial equipment step-down etc. and other work requirements. 12V to 3.3V, 12V to 5V, 24V to 5V, 24V to 12V and so on. Transfer Efficiency test data: Input 12V, Output 5V/10A, Efficiency 81% Input 12V, Output 5V/6A, Efficiency 86% Input 24V, Output 12V/8A, Efficiency 91% Input 24V, Output 19V/6A, Efficiency 94% Package Include: 1pcs 12A DC Step Down Buck Converter

Review: The output voltage adjustment potentiometer is next to the input voltage posts. When I powered on the supply the input voltage and output voltage were the same. Turning the potentiometer in either direction did not seem to have any effect but I eventually discovered that it needs many turns counter-clockwise before the output voltage started to lower (maybe 50 turns, I am not sure). Then I was able to set the output to the 5.1V that I need for the Raspberry Pi. And it is working great. The heat sinks are connected to the output voltage so be careful not to let anything conductive touch the heat sinks.
Review: Bought one to retrofit a 6v electric trike to run on 12v lead-acid batteries instead of the original, proprietary 6v battery more than a year ago. It still works!

Solder joints, splatter and dirty board. Didn’t even try plugging it up. I’m glad I inspected it before use, putting out a fire was not on my todo list. Ordered a replacement, I’ll update
