Re: [A/S] Surge/Low Voltage Protection

[Wayne Lindberg <wayne@xxxxxxxxxxxxx>]

I'm not an E.E. but I'd be surprised if there is a need for one on the 
12VDC distribution in the trailer.  Any transients occuring outside the 
trailer would have to get throught the Uni-Volt (or whatever they're 
called) and then past the batteries.  I would imagine that the 
rectification process would flatten any spikes from the outside world.  
And even if something got through, the batteries would be a low 
resistance place to shunt the energy.  The voltage monitoring is another 
issue.  It would be handy to know what the voltage is, but I wouldn't be 
concerned with low voltage hurting any electronics.  They pretty much 
just quit until the voltage comes back up.  The one exception might be 
the 12VDC funace motor.  I don't know how DC motors react to low 
voltage.  Personally I'd put the $250 in the bank against future 
failures or buy gas with it.  :)

As they say its my opinion and worth every penny you paid for it.
