Arc Dimmer – Introduction

My friend asked me if I could make him a push-button controlled LED dimmer, so I did! And went a bit haywire with the options list, as usual. Instead of making a single-purpose dimmer I decided to make it a bit more universal and bulletproof. Here are the basic specs:

  • operating voltage: 12-24V DC
  • load current: up to 10A (or more with a different output switch)
  • protected against overvoltage, overcurrent and overtemperature
  • two configurable control inputs
  • optional I2C interface for bus control
  • status and power LEDs

The PCBs arrived a few days ago and I assembled one unit for testing. A few parts are missing because they are on order and should arrive soon. Here are a few pics until I prepare the documentation:
