ShorPOWER® SPA Compact

ShorPOWER SPA Compact
Product Brochure

The industry leading ShorPOWER® SPA-II is a state of the art frequency converter containing features not available in any other converter on the market. An example of these is proportional load sharing between the two shore 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.

Unique to the SPA Compact is its ability to be operated in high ambient temperatures through a novel method of controlling the airflow in the unit. The compact form factor allows the SPA Compact to be installed where height is restricted, expanding the installation opportunities on board. Because of packaging techniques derived from the aerospace industry, the ShorPOWER®SPA Series system offers the lightest weight to kVA ratio in the market. No other marine shore power frequency converter approximates the low weight of the ShorPOWER® SPA Series units with the standard features included.

Worldwide Power
The SPA-II will automatically connect to any marina shore power source worldwide and provide clean, stable and reliable power 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 Shore 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. Onboard load imbalance, input power factor and input harmonics can reduce the available power from the marina to the yacht by 35%. The SPA-II converter corrects these problems and allows 100% of the marina power to be available. The SPA-II’s unique dual cord input increases the total available power from the marina since the two cords can be connected to different marina voltages or phases. The load is shared proportionally between the cords based on the marina breaker sizes, this prevents the smaller of the two breakers from tripping early.

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.

FEATURES
