Shore Power Static Frequency Converter
Convert the quay into the voltage and frequency the ship is built for, at a published overall efficiency of ≥95% at full load.
Cold ironing without guessing the local grid
Frames are published at 1000, 1250, 1600, 2000, 3000 and 4000 kVA. Input frequency is 50 Hz ±10% or 60 Hz ±10%. Rated output frequency is 60 Hz or 50 Hz or 400 Hz at 0.01 accuracy. Input and output voltage levels are described as customizable.
Rectifier options: 6-pulse, 12-pulse or PWM. Input power factor is ≥0.90 / ≥0.96 / ≥0.99 respectively. Input current THD is ≤35% / ≤6% / ≤5% at rated load.

Questions buyers actually ask
Do you ship a containerized unit?
Yes. The specification distinguishes container type (IP65, air-conditioning cooling) from indoor type (IP32, forced air).
Can output be medium voltage?
The current table prints both 440 V and 6.6 kV columns from 1250 kVA upward. Treat the exact MV package as a project item.
