Flow Battery Equalizer
Product Overview:
The marine shaft generator constant voltage & constant frequency cabinet is a dedicated control and power conditioning equipment matched with marine shaft generators.
It utilizes the rotating power of the ship main engine to drive the shaft generator, solving the problems of unstable voltage and frequency caused by the fluctuation of main engine speed during navigation.
The cabinet realizes real-time voltage regulation and frequency stabilization, outputs high-quality stable sine AC power, supplies power for ship onboard electrical loads, reduces the running hours of auxiliary diesel generators, cuts fuel consumption and exhaust emissions.
It adopts mature IGBT power conversion technology, integrates monitoring, protection and communication functions, and complies with marine classification society standards for ocean-going vessels.
Typical Applications：
· Ocean-going cargo ships, bulk carriers, container vessels shaft generator power system
· Coastal vessels, multi-purpose cargo ships main-enagine shaft power generation
