bigclivedotcom | Universal fan control module teardown - with schematic @bigclivedotcom | Uploaded January 2024 | Updated October 2024, 8 hours ago.
A look at a generic Chinese controller for repairing air conditioner units (not the compressor type).
This universal module can control three-speed fans, and two extra loads like a swivel motor and pump for an evaporative cooler.
It's functionally very similar to the PCB in a Hepa air filter unit I have here, although much simpler.
It's very minimalist. I think I'd rather it used a small buck regulator for the 5V rail, since the voltage falls significantly when driving three triacs and several LEDs on the display.
The capacitor in series with the coil based sounder is rated 820nF.
If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- bigclive.com/coffee.htm
This also keeps the channel independent of YouTube's algorithm quirks, allowing it to be a bit more dangerous and naughty.
