Surge Guard® RV Voltage Regulators provide a reliable, regulated source of power.
They continuously monitor line voltage conditions and use a special transformer to increase the incoming voltage to an acceptable level when incoming line voltage is low enough to cause damage to RV air conditioners, refrigerators and other electrical accessories. Seamlessly switches between two modes of operation:

Boost Mode-raises output voltage by 10% if incoming line voltage is between 95 Volts to 110 Volts. Bypass Mode-passes input voltage directly to the output when incoming line voltage is above 110 Volts or below 95 Volts

The LED Status/Fault Indicator Panel shows line conditions and voltage status. Each line voltage control circuit operates independently so that an increase in power only occurs on the required line. Fault tolerant units suffer no damage if an open neutral results in high voltage on one incoming line. Voltage Regulators work with Surge Guard® power protection devices (sold separately) to provide surge/spike/miswired pedestal protection to RV and appliances. Rain-tight metal case features mounting feet that elevate it off the ground so it doesn't sit in standing water when used outdoors. It can also be mounted inside a well-ventilated RV storage compartment.

We have used the 50 amp regulator for the past 18 months. Prior to having it we continuously monitored park voltages and saw drops to as low as 92 volts in some parks during peak periods. With the regulator installed voltage has never dropped to less than 110. As of September of 2010 we stopped continously monitoring voltages and now only occationally refer to the LEDs on the regulator. I believe this device has saved us from a lot of damage to electronic devices in our coach.

Bought this after suffering poor electrical service on two different occasions. The Surge Guard protected the coach, but got tired of going out and resetting the breaker and reducing the coach load on the campground electrical grid. I liked this regulator for its design, separate line indications and because it could be mounted inside my electrical bay, secure out of sight and the weather. By far, Camping World had the best price for the regulator and free shipping!
