PowerMaster Voltage Controllers

Why do I need a Voltage Controller for my RV?

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 smoke!

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 (better known as an 'autoformer' in the RV industry) 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.

Installation:
Installation Hook up is simplicity itself! Just plug it in to the incoming power post, then plug your RV's power cord into your PowerMaster voltage controller. That's all there is to it. PowerMaster's internal switching controls handle the rest automatically. Our design allows for secure locking to the incoming power post. These units may also be installed inside your RV bay for added convenience with the optional installation kit. For further information, please refer to the VC-30 Installation Kit and VC-50 Installation Kit instructions.
