I have read so many people getting the autoformers such as the new Hughes Autoformer RV220-50SP. The unit includes a replaceable surge protection device, so it seems like it does everything that the Progressive Industries surge protection units do but better. Here is what they say about it:
The all new Hughes Autoformer RV220-50SP has the same performance and reliability of the RV220-50 now with advanced surge protection in one package. The surge / spike protection unit is also replaceable. In the event of a massive spike, the surge unit will take the hit ensuring your booster and more importantly, your RV stays safe.
Now the Progressive Industries surge protector I am looking at is the EMS-HW50C. It says that it does basically the samething here:
Electrical Management System (EMS) helps to protect your RV against voltage fluctuations, power surges and incorrectly wired shore power which can cause severe and costly damage to RV appliances and electronics. Feel secure with multi-mode surge, voltage, polarity and lost/open neutral protection. Each unit includes a digital display scrolling continuously through the power source information. A state-of-the-art microprocessor provides peace of mind, day or night, even when you’re away from your RV.
What I am thinking is that since surge is covered and the Hughes Autoformer also does the boosting it would be a better unit to go with. Looking for any advice from the community about the differences and what they have gone with, seems like a no brainer to me.
