## Overview

The Daygreen 24V to 12V Power Buck Module is a high-performance DC-DC converter designed for automotive applications, delivering a stable output voltage with robust safety features and exceptional efficiency.

## Description

Wiring: INPUT+ to BAT+, INPUT- to BAT-, OUTPUT+ to LOAD+, OUTPUT- to LOAD- Reminder: Never reverse the polarity. Use the enough big cable to avoid the voltage drop. Never connect to solar panel or wind turbine. Never charge the battery.  Daygreen P/N: B40-24-12AEfficiency: 95% Input Voltage: 21-35VDC Output Voltage: 12VDC Output Current: 40A Ripple: 200mVp Line Regulation: ±0.2% Load Regulation: ±0.2% Voltage Accuracy: ±1.5% Enclosures: IP68 Dimension: 100*80*40mm Net Weight: 0.5kg Case Operating Temperature: -40~85°C Certificates: CE Rohs Warranty: 1 year1 MTBF: 100,000 hours Application: 24V DC battery of vehicles as input power to 12VDC appliances as output load. QuestionsHow to choose the correct current for loads? For example, if the max current of your load device is 10A, then choose 10A/0.8=12.5A at least for resistive loads according to international standard. If the load device is motor or compressor, then you may choose 10A/0.5=20A according to real testing result since the motor and compressor starting current may be 2-3 times than nominal current.

## Features

## Questions & Answers

**Q: can I add a 12 volt alternator or charger to the output to charge the 24 volt supply battery?**
A: This converts 24v to 12v not the other way around. Now as far as your question. If you have 12v battery's wired in Series to make it a 24v battery then yes you can use a 12v alternator to charge your battery's. Personally I wouldn't buy this unit again as It burnt up upon 1st use.

**Q: Do you have to install a switch between the converter and the battery to stop battery drain or will the batteries be ok hooked straight in line?**
A: The drain current is less 0.04A. Thanks.

**Q: What is the voltage out?  12 Volts or 13.8 Volts.  Can it be adjusted?**
A: This output is 12V and the voltage can't be adjusted.

**Q: If the output short circuits does the unit protect itself or should I add a fuse?**
A: You could add a fuse, but in fact, it's no need. Thanks.

*by J***N on Reviewed in the United States on September 17, 2023*

Been using 3 of these for 4 years... working perfect in my bus conversion...have not been turned of in 4 years though I am putting high current relays in as they do draw a bit of power even when idle so they  will only turn on when the ignition is powered up
