Power Supplies Module, DC-DC DC-DC Buck Converter 6.5V-60V to 1.25-30V 10A Adjustable Step Down Converter Power Supplies Module

this unit works great but it heats up like crazy. I was afraid it was going to burn up so I decide to use it on a temporary.

Utter pile of trash product! Do not purchase! Upon connection to a 48 volt source with no load this unit catastrophically failed! It created a large spark, lifted a (very wide) trace off the board, destroyed a connector, destroyed a 22awg wire, and destroyed a Antispark Switch Pro 280A from Flipsky worth $40!

I could not change voltage output of this unit. Have had better luck with other brands.

They work exactly as intended. I'm using it for my 52V Electric Scooter which has 12V rear turn signal. I also purchased 1" in diameter Clear shrink wrap to keep it protected.
