30 Amp Controller

The MVC-30 incorporates revolutionary new internal switching control for simple, problem free operation. Also, the surge protection feature rivals that of expensive, commercial grade surge protectors.

Features


50 Amp Controller

The MVC-50 is a dual transformer 50 amp controller for those pleasurecraft and commercial vessels with a 50 amp power requirement. The VC-50 has the same outstanding control and surge features found in the VC-30.

POWERMASTER NAUTICAL VOLTAGE CONTROLLERS

The Age Old Problem
Every boater is familiar with the adage: ‘Water and electronics don’t mix’. Even though they are engineered to operate in marine environments, boat appliances and electronics often fail. What many people don’t realize is that oftentimes electronics failure is due to low voltage problems not moisture, corrosion or other issues caused by the marine environment.

Boats Have Changed, Marinas Have Not
Not too many years past, if you looked down the average dock you'd see a line of modest daysailers and single-engine outboard sport boats. Today, boats have grown to become second homes. They often have air conditioning, refrigeration, microwave ovens, televisions and a suite of sophisticated electronics. Even sport boats often include refrigeration systems and powerful stereos. The combined demand of numerous boats on a dock can quickly outstrip a marina's ability to deliver adequate voltage.

When the delivered voltage is less than your electronics expect, they draw more current, creating damaging current draw and heat. Evidence of this situation can be found in premature A/C motor failure, refrigerator control boards burning out, TVs burning up, shore power cables exhibiting signs of heat damage, etc. If your shore power cable has ever shown signs of getting too hot, your boat has suffered from low voltage.

Remember, if you're cooking your shore power cable, you're cooking your boat!

STEP UP TO A POWERMASTER

THE ONLY MARINE SOLUTION THAT INCORPORATES
BOTH BOOST & SURGE PROTECTION

PowerMaster Marine Voltage Controllers boost voltage by up to 11% (50 amp model) or 18% (30 amp model) when required to prevent damage to your boat and allow you to operate your A/C and other electrical appliances where low voltage prevented you from safely using them before. These machines are fully automatic and provide sufficient surge protection to protect your boat against anything up to a direct lightning strike.

BOOSTING VOLTAGE TO APPLIANCES AND ELECTRONICS
MAKES THEM RUN MORE EFFICIENTLY – USING UP TO 25% LESS ENERGY

This savings in energy consumption can either be realized in reduced utility bills or the ability to safely operate additional electronic devices and appliances.

Hook up is simplicity itself; just plug it in. Our design allows for secure locking to the incoming power post or onboard installation. We are so confident with the quality of PowerMaster Nautical Total Voltage Controllers that we offer, at no extra charge, a two year limited warranty on these devices.
