what is power conditioning board...

[ECET0purdue]

quick question.... this is what i was told about the screen.

Not sure how you plan to power the unit - this model comes with 8 to 26 VDC.  If you are supplying power, it will be fine.  If you plan to power this unit with the vehicle power as the source, you will need a vehicle power conditioning board.  If that's the case, I will need to make up a special unit.

why whould i need an power conditioning board? and what would be the purpose?  i could just say yes i need it but then it would take longer iam guessing to get to me... do i really need one of these...
thanks
