DC 24V to DC 12V 10A 120W Step Down Buck Converter Voltage Regulator Reducer Power Converter Mini Module 12V Transformer

April 25'Application in an RV to reduce 24V solar battery system down to 12V for standard RV loads.Idle current draw is 11mA @ 24V and 10mA @ 28V.Measured ~95% efficiency @ 2.5A output.Pout (11.99V * 2.5A) / Pin (27.65V * 1.14A) = 95%Wish there were proper specifications, but it seems to operate at 28V, topped off 24V batteries.

Used it down grade the 20 volt dewalt battery for amy 12 volt invert. Works great

Used this to convert 24v battery system to 12v to run some accessories. Worked as expected. This is nice and small (easy to tuck away) and simple to use (clearly marked terminals)

This 24-12v converter is stable and efficient but only capable of about 90 watts of continuous output (which is about 110w in at 19v). Above this, the voltage sags unacceptably.I measured the following output efficiency:1w @ 61.90%5w @ 82.94%30w @ 94.56%60w @ 92.96%90w @ 91.83%Ripple was 89mv across the rangeVoltage sag was 0.5v beyond 30wTemperature at 90w output was about 130F after 10 minutes which is fine but I would probably recommend providing some airflow.If you need > 90w output power, do NOT buy this.

After buildinf the enclosure for my 3D printer I was looking at ways to both filter and vent the build. With my first design I ended uo using a 12v high air flow fan, but coming off a 24v board I needed a cheap and easy way to step it down. This did the trick and has been in use for basically the past year.

Good

Doesn’t work got 24v on one side. No power on 12v side
