SUPERPLUS Motor Speed Control Board, DC 10-50V 60A High Power Motor Speed Controller PWM HHO RC Driver Controller Module 12V 24V 48V 3000W Extension Cord with Switch (Blue)

Worked ok until I let the smoke out. Not sure what went wrong.

Used it to replace the motor controller in my welder added a ac to dc converter and it works perfect. They wanted $175.00 for a new board and i did it for under $30.00. Thank you.
