My soft start boards arrived this week so I am just about to order the parts from the BOM as the first stage in an Aleph J build. Could someone please confirm that the parts on the BOM are all suitable for use at 240v? This is my first DIY electronics project (I've built lots of speakers over the years) and as this bit connects directly to the mains I thought I'd better check!

I've built one for an Aleph J on 240VAC mains. No problem. I'll check what I ordered against the BOM and let you know of any variances. I don't recall anything significant.

I just built one for 230V using the standard BOM, so you are good to go.

Hello. I use balanced AC power for my system (60V & 60V invert). Would this circuit be compatible with that?

Built my boards but I'm struggling to see the point of SW1 connection. Is there any reason why I can't just connect the mains directly from my double pole power switch to neutral and SW2?

Just ordered a couple of these boards on the Black Friday sale. I plan to use an external Z-wave appliance module in place of the Power switch. In this case I think that C1 could be eliminated. These modules are rated for 15 amp motor loads so I am assuming they have some form of internal protection. There are a variety of remotely controlled switches available these days that can be integrated into home control applications.
