I have purchased a GXW4008 and would like to run it direct off a 12V battery. I’m sure this would work fine but what concerns me is when the battery needs to be charged the voltage could go up around 14.5V. Also if there is a power outage the voltage might drop below 12V, although I am looking at low voltage cutouts.
My other option is to run it from a UPS but my UPS has other loads on it and run time isn’t that long. It’s also a lot less efficient boosting the voltage to 240V just to bring it back down to 12V. With a separate battery I could have something that would keep the voice connection running much longer.
Is there voltage input range data available for the GXW4008?
