Review on Teyleten Robot 1500W 30A DC-DC Voltage Step Up Boost Converter Module 10-60V to 12-97V CC CV Power Supply with Fan by Zack Frazier
The op amp is dirty, needed resoldering
So if the item is intact it works fine, these converters are one of my favorites. I turned it on and was greeted by the OCP LED giving the error. I found the schematic and found the op amp that was part of the circuit, I looked closely and the soldering didn't look right. I pressed my finger on the op amp and it worked. The pins on the left were soldered while the right side lay slightly over the tracks and not touching. Soldered the op amp flush to the board and it worked.
- Good product for the price
- Ugly packaging
