Minimum voltage

[PitMan51]

We’re at the Blue water RV park just West of Galveston. We finally got power back on, but it’s only at 109 volts. Any thoughts on if that’s enough. Is it usually safe to rely on the surgguard?

I'd have to dig out my surge guard specs , but if memory serves , low voltage cut out is 107 volts .
With only 109 , be cautious what you turn on as even a couple of small loads can trigger the shut down .

EDIT: A quick read of my manual gives range as 102 volts low and 132 volts high as operational range . Your system may vary.

While different electrical devices are more/less susceptible to damage from incorrect voltage, most will work with 120 VAC +/- 10%. So, 108-132.

102 is too low for most equipment.

We’re up to 116v. - but still curious about minimum voltage with the vansco

Yeah, that sounds more like it.

Think my PI EMS shuts down power at 104V.

Depends a lot on the load. Something like incandescent light bulbs don't care at all. A "universal input" SMPS like you might find on a laptop or phone charger, and many electronic devices are spec'd to run down to 85V. Things like the converter for the RV are likely to operate at a wider input spec to work within operating conditions less than optimal, like long extension cords. Likely the worst impact there would be reduced output or increased EMI. The only device I would be concerned about would be anything powered with an AC motor that's both voltage and frequency sensitive.

The Vansco is for the chassis, it doesn't run any of the living stuff. I don't believe that is even has any pole power going to it.
Someone correct me if I'm wrong.

The Vansco is powered by 12V from the chassis batteries. And yes, it controls 12V automotive functions.
