Review on Buck Converter 24V to 12V, DROK Power Supply Module DC 5-32V to DC 0-30V 5V 1.5A Adjustable LM2596 Step Down Voltage Regulator with LED Indicator by James Wonsley

Does pretty much what it says on the tin. I checked the accuracy of the output and input voltages shown on the display with a Fluke digital voltmeter and they were within a few millivolts. This is just a buck converter. I misinterpreted the description and hoped it was a boost/buck converter nicked at this price. Although it's just a buck converter, it's excellent. I found that under heavy load (2A load) the device gets very hot, so I think it's advisable to reduce the load. The instructions for setting the tension seemed a bit confusing, but it's easy to figure that out by experimenting. Be careful when changing the voltage on resistive loads, as the output voltage changes immediately after pressing the + or -set button. I would prefer a delay time to set the final voltages before the output actually changes. I've found that it's better to go with the 1/10 volt setting and tweak that instead of the 1 volt setting. The 1/10 volt setting is adopted so going from say 1.9 volts to 2.5 works like 1.9 - 2.0 - 2.1 - 2.2 - 2.3 etc.
