>>I don't remember where I got enclosures from

These sound like Sarel enclosures. You can get them from Wholesale=20
Fittings=20
(WF) in Guildford.

We buy loads of kit from WF so if you want a good price, drop me a line=20
off=20
list. You would need to buy some top hat DIN rail and a back plate.

I think a 600x600 metal enclosure is about =A370, the back plate is
about=20
=A315=20
and the DIN rail is about =A35 for 3 metres. Much cheaper than an
equivalen=
t=20

dedicated DIN enclosure.

Cheers

Neil
