High voltage shore power supply


BOS high-voltage big capacity shore power supply mainly adopt the input transformer, power units and other components connected to each other. The shore power structure is with multiple units in series, the output parts with multi-level phase-shifted PWM technology, which make the power supply be high reliability, small size , Greatly reducing the manufacturing materials, light weight, easy to move; automatically match the optimal technical parameters, reducing the wiring inductance; Compared with the traditional design and equipment which with higher cost performance; With 50 Hz / 60 Hz dual-frequency power switch and can provide shore power to different types of ships. Compared with generators, the energy saving is more than 20%. It also solves the inconvenience such as high noise, high running cost and difficult maintenance. The function is stronger applicability. With color man-machine dialogue interface, Chinese menu display and intelligent power distribution monitoring device. Real-time monitoring the power.


High voltage shore power supply

1.Rated input voltage: input power for the three-phase 10KV / 50HZ industrial power supply. (AC voltage allowable fluctuation range ± 10%)

2. Rated output voltage: the output voltage according to user needs, to provide a variety of voltage levels, 6KV / 6.6KV / 10KV. In this case,

3. Rated output frequency: 60HZ / 50HZ (can be arbitrarily converted)

4.Output frequency accuracy and stability: output frequency error ≤ 0.01Hz; stability <0.01% (0 ~ 100% load change, the frequency unchanged)

5. Output voltage regulation rate: static <3%; dynamic <5%

6.50% load sudden increase / decrease when the output voltage instantaneous change: <5%, and 0.5 seconds to restore to the rated output voltage

7. frequency power overload capacity: 120% 2 minutes; 150% for three seconds; 180% immediate protection

8. Output voltage waveform Total harmonic distortion: THD ≤ 1.2 ~ 2.8%;
