#Why Is RV Voltage Control Important?


The most compelling reason is that replacing appliances is costly (not to mention inconvenient, a waste of time, and a hassle to get them replaced). And more often than not, you don't even realize there's a problem until you see the Brian Salm's photo of a dangerous electrical panel athttp://www.independentinspectors.org/smoke! And when you consider the fact that RV parks may have varying types of electrical systems and quality of wiring equipment they use to deliver power to your motorhome, then you can start to see the wisdom of having a good Voltage Controller. A good voltage controller (better known as an 'autoformer' in the RV industry) can protect your appliances, electronics, & electric motors from damage and premature wear.

Many AC motors will burn out when they draw too much current, which is what happens when there's insufficient voltage. When the power supplied by the park is too is low for an appliance or group of appliances being operated (for example, if you're running both the air conditioning and the microwave), you generally can't run those appliances or any additional appliance without risk of damage.

Voltage controllers are designed to increase voltage to your RV and help eliminate low voltage damage to your appliances. Unlike a 'boost transformer', PowerMaster autoformers will automatically adjust the output based on the load demand. Therefore, you can run additional appliances on a 30 amp input. For example: a coffee pot and microwave each draw 1,200 watts for a total of 2,400 watts. Add wattage for the converter and refrigerator about 800 additional watts and you have 3,200 watt demand. If you are only getting 100 volts from the supply, the maximum wattage would be 3,000 watts.

The output of the PowerMaster autoformer will self-adjust depending on the demand. With the increase in the voltage to the RV (through the voltage controller) the amperage demand will be lower and the overall performance will be greater. Your appliances will operate smoothly & efficiently without premature wear & damage to motors and compressors. With an operation range of approximately 94 to 125 volts input, the PowerMaster autoformer will boost your RV voltage to safe & efficient levels.

Power Master Voltage Controller's - The Smart Choice for Protection!

Now you can camp at any R.V. park and not have to worry about the potential damage 'bad' wiring can have on your coach's sensitive electronics and electric motors. The PowerMaster 30A & 50A Voltage Regulators (a.k.a. autoformers) incorporate revolutionary new internal switching control for simple and problem-free operation.

Power Master Voltage Controllers for your RV or motorhome can help protect your appliances & electronics from power surges and other electrical conditions such as low-voltage.Not only will these autoformers help regulate the power being fed to your appliances & electronics from the sometimes inconsistent levels at many R.V. parks, but they include BUILT IN surge protection as well. The surge protection feature now rivals that of the expensive, commercial-grade surge protectors. In fact, they can protect your R.V. from a surge roughly equivalent to anything less than a direct lightning strike! (Well over DOUBLE the protection provided by other brands.) They come with a 4 year limited warranty.
