50 Amp RV Voltage Regulator

Catalog Item # 42293

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.

Bought this after suffering poor electrical service on two different occasions. The Surge Guard protected the coach, but got tired

I think, at least, I should get a replacement for the surge guard 10175.

No, this voltage regulator meets the requirements of a rain-tight enclosure for operating in an outside environment, but should not be left in standing water or submerged.

This will work on a 30 amp pedestal with adapter plug, yes.

I see it is able to control power overage and underage, but nothing on surge protection. How much surge protection does it control?
This device does not protect against faults or surges.
