12vdc adapter advice

[terryhawkins]

I am looking for an AC to 12V DC adaptor that I can connect to a fused spur to power a thermostat.

I would rather it was hard wired and not one that was plugged in (otherwise I'll need to install a socket for no reason) and it will be mounted inside an airing cupboard.

It will only need an output of 200mA.

I have come across this on my searches and would like to know if it's suitable:

If so, what is the best way to mount to a wall as I know it's made for din rails. Are there single enclosures or something like that?

Yea we get similar styled ones from our wholesalers for about £3 for site temp boards and the like. Sector is certainly a nice cheap brand

1) Check what the maker means by "DC", because one thing you can be pretty much guaranteed is that it isn't real DC.

2) Having found that info, check with the maker of the thermostat that it will be OK.

Plan B - do the people who make the thermostat offer a 12V supply for it?

If you get one that has a plug on, you can simply cut off the plugs and wire it direct.
This should also then already be in an enclosure so cost far less.

Looks like a great firestarter. I wouldn't buy one like that which doesn't have some appropriate approvals.

Never known that sort of supply catch fire. They are used in their thousands on set top boxes etc.
That one has a C E mark that looks genuine.
