Power supply voltage

[George Thornton]

I am about to put together a backup power supply system.  I have AGM
cell batteries and will be using a West Mountain PowerGate P40s and an
Astron RM35 power supply.

 

The West Mountain literature recommends that I boost the power supply
voltage to 14.5 volts in order to assure proper battery charging for the
AGM batteries.  

 

What will 14.5 volts do to the K3?  Am I risking something here, or is
there no problem with this setup?

Hi George,

                  If you are concerned a silicon diode of appropriate
current rating in the power lead will give a pretty constant .6-.7 volt
drop and you will be right back to the nominal desired voltage.

The K3 is rated for use up to 15 volts DC, and I regularly run mine at
14.5 volts for better transmit linearity.  I've had it since January of
2008 and it has been through several pretty intensive contest operations
since then without a single glitch.
