The output of these inverters is cabled to the ship service switchboard. BATTERY CHARGING CHARGING CONNECTION FROM SHORE For smaller vessels, it is simply not economically feasible to design and institute automated connection for charging. Compared to the 30 seconds it takes for a deckhand to plug in a 400A connector, these systems are just too complex and expensive. The power to the connector is typically provided by a transformer that converts a high voltage utility power (typically 11-45kV) down to a voltage suitable for installation on a dock or pier (The National Electric Code limits this to 1000V; NEC Article 555.4). RECTIFIER/CHARGER 3Ø/400-690Vac/60Hz is received from a shore power transformer via a shore power connection (typically 200-400 amps) and supplies power to a three-phase rectifier cabinet. The rectifier utilizes power electronics components to modify the alternating current input to a direct current output, TECHNOLOGY QUALITY FERRIES FROM THE VIGOR TEAM 400 PASSENGER FERRY 144-CAR FERRY VIGOR.NET MARINESALES@VIGOR.NET
