The ShorPOWER® SHF frequency converter utilizes state-of–the-art technology including the latest generation of power semiconductors and transformers controlled by an ultra-high speed digital system to create precisely regulated output power. This technology allows the marine power converter to be very compact and lightweight while being electrically powerful and highly efficient.
Worldwide Power
The SHF will automatically connect to any marina shore power supply source worldwide and provide clean, stable and reliable power for the yacht. This is especially important due to ever increasing regulations regarding the use of onboard diesel engine generators while docked at a marina. Noise and air pollution caused by these generators, coupled by increased operational and maintenance costs, make the use of the ShorPOWER SHF frequency converter a must.
Advanced Power Design
The ShorPOWER SHF produces a highly regulated output regardless of fluctuations in the dockside power or changes in load onboard. This regulation protects the onboard marine electrical system by eliminating voltage transients and harmonic distortions typical of dockside power.
Reliable Power
The SHF is designed to be the most reliable converter on the market by manufacturing the converter using only the highest quality components and by engineering the converter for actual marine use, such as operating continually at 100% load in high ambient temperatures.
Marine Engineered
The compact lightweight form factor allows the SHF to be installed where height is restricted. Additionally, the ability to mount the system in either a vertical or horizontal configuration expands the installation opportunities on board. The SHF is designed as a dual input machine to maximize the use of available dock power supply.
