CPI Range Plus. Transformer question.

[Low_Boy]

I have a CPI Range Plus that the transformer has went bad. The range plus has a pretty hefty transformer in it. I am just figuring I will do away with the transformer and run this off a wall wart. I think that is what they are called. Plug in power supply. Does anyone have a idea of how many amps this will draw at 12V? Basically I am not sure what size to get.

Looks like around 4.5w according to my meter.

Thanks Mike. .375 amps would I be safe with 1 Amp?

Your math is correct. I would think 1A would provide sufficient head room. Any of those 12v/1A wall transformers that you can get on eBay would probably be the cheapest route. I would check the circuit or schematic to see where those 12v connections on the back go to. Any further regulation or fuse?

Just make sure you get the polarity right. I'll guess that there is no reverse-polarity protection on it.

Might be, but making sure before you flip the switch is always better.
