RE: 12V power supply?

["Christian Cundall \(UKHA\)" <ukha@xxxxxxx>]

Prhaps you are all missing the point with power supplies - use a PC power supply, you have 5+ 12+ and usually at 12 to 20 amps. I have a PC power supply running a 12 volt ring main in my house and vola no more wall warts.

 

You just jumper pin 14 of a PC power supply to neutral and the power supply kicks into life.

Tim,

 

What current rating do you need ?

 

CPC do a few "Power Supply Modules" (page 1019, 2003 catalogue) in their "Kits & Modules" section of the catalogue (I presume "module" means it comes ready-assembled):

 

12Vdc (or 24), stabilised (regulated ?) with the choice of 1A, 2A, 5A & 10A ratings. Prices range between GBP 15 - 60 plus VAT. The pictures doesn't show cases.

 

 

Alternatively, there's the "Bench Power Supplies" (P1445) where you can select the output voltage. Some go up to 10A and all have cases. Prices top out at around the GBP 150 mark for the 10A unit.

 

HTH,

 

Tim H.

(not put a ring main in, just knew I'd seen the PSUs somewhere)

For those of you that have installed 12V ring mains, what supply did you use? I’ve managed to find a DIN rail mounted 24V supply at RS, but for one it is 24V and secondly it is unregulated.

 

Tim.
