Marina ShorPOWER^® SPA-II

The industry leading ShorPOWER® SPA-II is a state of the art marine frequency converter containing features not available in any other converter on the market. An example of these is proportional load sharing between the two marina shore power cords and the ability to operate into a 100% imbalanced load while maintaining the precise regulation of all the output phases. Built using the latest power semiconductors and ferrite transformers the SPA-II is controlled by an ultra-high speed digital signal processor to create an absolutely pure output sine wave.

Worldwide Power
The SPA-II will automatically connect to any dockside marina power source worldwide and provide clean, stable and reliable marine power supply for the yacht. Fully compatible with all types of marina breakers and complying with shore supply regulations, having an SPA II on board makes the yacht a truly global vessel.

Advanced Power Design
The ShorPOWER^® SPA-II frequency converter utilizes state-of-the-art technology including the latest in power semiconductors and ferrite core transformer technology, all controlled by a ultra-high speed digital signal processing control system to produce an absolutely pure output sine wave with no distortion.

Reliable Power
The onboard guests do not want to be aggravated by flickering lights, black-outs and generator starts caused by fluctuations in the marina power. Regardless of the dock power quality the SPA-II will always produce stable and reliable power. This reliability is achieved by manufacturing the converter using only the highest quality components and by engineering the converter for actual marine use.

Maximize Marina Power
Many yachts have to reduce their air conditioning and galley loads when in the marina to prevent overloading the circuit breaker on the dock and losing all power. The SPA-II converter increases the amount of available power from the marina by as much as 100%, that’s 35% more than other comparable converters.  By adding a second shore cord the available power doubles again.

Marine Engineered
Designed from the ground up, based on years of marine experience, the converter is packaged in a lightweight aluminum enclosure and is engineered to operate in the worst marine conditions such as high ambient temperature and humidity. It has been extensively tested to ensure that when loads such as large motors and compressors start there are no fluctuations of the output power.
