Stable electrical power is essential and expected on luxury yachts today, but all too often the lights on board will flicker or go out and systems essential to the enjoyment of the yacht such as the air conditioning have to be limited because of the available power from the dock. By installing a ShorPOWER® ULTRA LP™ these problems become a thing of the past.
Worldwide Power
The ULTRA LP automatically connects to any low voltage marina power source worldwide and provides clean, stable and reliable marine power supply for the yacht. Ideal for yachts under 120 feet the Ultra LP is fully compatible with all types of marina breakers and complying with marine shore power supply regulations, having an ULTRA LP on board makes the yacht a truly global vessel.
Advanced Power Design
The ULTRA LP marine shore power frequency converter utilizes state-of-the-art technology including the latest in power semiconductors and grain oriented transformer technology, all controlled by a high speed digital control system to produce a pure output sine wave.
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 supply quality the ULTRA LP 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. By balancing the currents in the shore cord the ULTRA LP converter increases the amount of available power from the marina by as much as 20%.
Marine Engineered
Designed from the ground up, based on years of marine experience, the converter 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 actual marine power loads such as large motors and compressors start there are no fluctuations of the output power.
