Mark V maximum voltage input

Hi Everybody,

What is the absolute maximum voltage that can be applied to the DC input jack? I know it can handle 12 Volts, but how much more before damage will result?

I'm thinking of situations where the Mark V is connected to a SLA battery AND a charging system that can raise the voltage above 12 V. Most lead acid batteries charge systems float around the 13.8 Volt level... some up to 14 Volts.

I'd like to use the Mark V while in my car... but don't want to damage it. Same thing would apply to a solar panel & battery setup.

Luno.

It takes 5v to 12v. Leeway?

Oh well... that rules out using the Mark V in a car (at least while the engine is running) and in a remote situation where a battery is augmented with a solar charging system.

I'll use an external TracoPower 5V regulator to give the Mark 5 a nice stable 5v power supply. I did the same thing with my Raspberry Pi Portable D-Star HotSpot.

I've got some Traco Power TEN 9-2411WI DC-DC converters lying around here somewhere. I'll make up a small regulator for the Mark V.

9-36V in, 5V 1600 mA out. Plugs into a DIP-24 socket. I also like 'em because they are VERY RF quiet.

How about this for in the car?

yeah that would work... but I'm not a fan of the cigarette lighter plug system for power. I've been using 30A Anderson Power Poles for all my ham radio gear. Plus I like building stuff. :)
