Hi Mike,

The 12 DC input to the P3 is connected internally to two DC/DC converters.  These both have over current protection and limit at less than 1/2 amp each.  Probably worst case is 1 amp.  Of course if the cable itself shorts out or the regulators somehow short at their inputs we would exceed that.  Certainly putting an external fuse inline with the P3 power supply wouldn't hurt.

Hi Paul,

I'm curious about circuit protection. If I connect this cable directly to my 35 amp 12V power supply is there any over current protection within the P3? I understand that the cable itself might go up in smoke but at the present time I'm only really worried about the P3.

Hi Bill,

We're going to start shipping a 6' 2.1MM power cable with every P3SVGA board ordered. The other end of the cable is bare and can be used to connect the P3 directly to your 12V mains. This should start by tomorrow or the next day.  If your SVGA hasn't shipped yet, there'll be one in the box.  Anyone who has already received their SVGA board can simply contact the factory and we'll send one out.
