Power Conditioner vs Surge Protector?

I have Progressive EMS now. Only use Frank's if EMS cuts power to my air conditioner. Has not been an issue in the last few years but still glad to have the option. Only used if I need air and have low voltage in our vast desert. Due to the breaker issue I run everything else on propane/solar/inverter when in Frank mode.

Supposed to have some surge protection and I would not count on much. Unplug if lightning is close and frequent.

Thanks SMK. So you do use Frank's device when continuous power is important?

Hey, it seemed to work pretty well for Marty McFly! :W

More like 1.21 gigawatts :B

Frank's Superautomatic does that.
I have the 30 amp and I don't recommend it.

There is no delay to the power off-on cycle. Under the right circumstances I have seen it switch on-off-on-off in rapid succession.

Thermal circuit breaker rated 35 amps seems to trip way too easy if running 20+ amps continuous. Anyway it trips before the 30a pedestal or 30 amp RV main.

Voltage seems to hang high for too long as it will hold 128-129 volts when it could just bypass. Also my Kipor has a bit high voltage under no load so it has presented an issue if nothing is immediately on. For me it seems to cut off a bit early on the top side.

Mine is eight years old and not really used much although a few times it was really needed to correct low voltage and keep the air on.

Otherwise I recommend Progressive Industries EMS.

Unplugging will help with lightning-caused surge. There can also be a direct damage from the lightning bolt itself, and for this he would need a lightning rod with suppressor. Have seen it on permanent campsites, but on the movable rig - not sure.

We normally camp on electric sites, usually only dry camp without power when there's either no electric site available or we have managed to get one but for one reason or another the power isn't suitable or even quits, sometimes for hours or even a day or two. This seems to happen to us several times each season so last year I finally installed a 1000 watt PSW inverter so we at least have some limited access to 120 vac shore power when our campsite can't provide it. This year I plan to replace my aging G27 battery with a pair of G31 batteries that will significantly improve our ability to sustain ourselves without shore power for much longer periods of time. In the meantime, while we are without campsite power, my Progressive EMS-HW30C continues to monitor the line and will only restore power to the trailer once it's satisfied that all is well with that incoming power. And like most, if lighting is expected I'll unplug entirely and use my battery / inverter source instead to keep us going until the weather passes.

Despite the advertising hype and guarantees, these devices are mainly intended to protect from transient spikes that happen all day long on power lines from grid switching, heavy motors, etc. Some of the better ones also detect low voltage and either drop the line or boost the line a little.

Lightening protection and power conditioning are two vastly different unrelated subjects.

Power conditioning is used to clean-up "dirty" power and restore true 60 cycle power of the desired voltage.
