Prefabricated Cabin Shore Power Variable Frequency Power Supply
1. Overview
The JDFSP series prefabricated cabin shore power frequency converter utilizes mature high – capacity high – voltage or low – voltage frequency converters as the research and development design platform. The program has been specially optimized for power supply, featuring mature technology, reliable quality, and good stability. It covers multiple voltage levels such as 0.38kV, 6kV, and 10kV in the port power grid, fully adapting to different power supply system requirements of customers. It is widely used in ships, ship manufacturing and repair plants, offshore drilling platforms, shore terminals, and other fields that require 50Hz industrial electricity to be transformed into 60Hz high – quality frequency – stabilized power supply, to supply power to ship electrical equipment.
2. Model Specification
