Progressive Industries EMS Alerts Me to Low RV Park Voltage Problem
Today I found myself staying in an older RV park campsite with rather low voltage on the AC power pedestal feed. If I ran anything more than about 1500 watts, the AC voltage began to drop dramatically. For example, if I attempted 3000 watts, the voltage sagged to around 101 VAC.
I thought this would be a good opportunity to show how my
Progressive Industries EMS
(Electrical Management System) warns me about it and kicks the power off. Once the voltage drops below 104VAC, it disconnects the incoming power input to protect the RV electrical system and devices plugged into it. The EMS LED display panel showed an error code PE4, indicating a low voltage condition.

My Autoformer has performed well over the last two years. I can monitor the voltage inside with a small l.c.d. plug in unit. I can't recall my voltage ever getting below 112v over this time but the park voltages where we go are sturdy enough power-wise to deliver good power. Thanks for the video!
