AC400 Record Power air filter - not working

[donturner]

Many thanks for that info. Another quick question if you don't mind.

I noticed that the manufacturer's original board has a fuse next to the 240V input, this new design doesn't. Just interested to know whether it was a conscious decision to not include a fuse on this new board design?

Looking at the specs for the machine, the motor is 120W so at 240V that's a draw of 0.5A. Would it be worth changing the wall plug fuse to something lower, say 3A?

Slightly concerned that if a short were to occur, or the fan motor develop a fault, there could be a significant heat build up / fire risk.

@thikone PCBs arrived from JLCPCB today. What IR receiver module did you use?

How did the PCB work out for you? Tempted to do the same myself.

I'd be tempted to put a glass fuse inline. The holders are fairly ubiquitous.

Mine has it externally, not on PCB.


Number 39 is fuse holder, 39 is the fuse and 40 is the fuse cap.

That is how it is sold in EU. In UK you have the fuse in the socket plug. But if you want then sure just add it and reroute the PCB. You can even submit it to GitHub.

As always, as DIY customization do it on your own risk.
