All in one compact unit, 50Hz three phase in the Port available automatic detection, automatic phase rotation applied and only the Isolation Transformer pass the energy to main panel. No extra consumption of Energy no extra heat.

The unit detects 60Hz or only one phase automatically the converter steps in and produce the correct 50Hz and three phase 400V for the main panel.

Shore Power is lost, or no Generator Power available, automatic UPS 0 seconds kicks in to avoid black ship, useable time depends of UPS battery bank, and the switch off from non preferential consumers, output for this function available.

MYS WWSP series Power phase converter, adopted AC-DC-AC circuit structure and SVPWM modulation control technology, which can convert ordinary single-phase shore power to Yacht three-phase power. One, two phase to three phase ,3 phase to 3 phase and so on. MYS WWSP output is standard pure sine wave, the harmonic distortion rate (THD) is less than 2%, totally and we meet the international standards power quality, applicable to all types of load.

 MYS WWSP series shore power converter, the phase angle is 120 degrees

MYS WWSP series shore power converter use only 1. brands material like Schneider marine certified breakers, Wago clamps, Mitsubishi Electronics.

MYS WWSP series shore power converter will solve electric shore power compatibility in world areas because of the inconvenience the supply not match frequency 60Hz or voltage 120/208/440 V AC, but also solve the limitation of shore to only supply one or two phases.

 

Tecnical Description

We use last generation high efficient IPM intelligent module from Mitsubishi, very efficiency and stable performance. IPM has powerful protection function, protection for short circuit, over load and over temperature.

 Pure sine wave output with good transient response less than 50ms, waveform distortion is very small, we have higher conversion efficiency and stable output voltage.

 For complete ship isolation to shore we adopted to integrate low frequency transformer which ensure the input voltage and output voltage are completely electrical isolated to avoid corrosion effects on board.

 We use the SVPWM space vector algorithm, this guaranty high conversion efficiency, high instantaneous power and low no-load loss conversion, our can we reach more than 94% efficiency rating, to no burn energy to heat.

 Also the Converter has the function of filtering the grid disturbance and interference at the same time, which is a good performance of stabilized voltage and frequency power, to provide a more stable and pure power supply environment for the backend devices.

 The output is perfectly protected, with over-voltage, overload, short circuit, over temperature and we have a self-diagnosis.

C

Containing a built-in dedicated drive circuit to extract more performance from the IGBT chip, IPM (Intelligent Power Module) is a high-function module with a dedicated IC for self-protection functions (for over-current, undervoltage of control power supply and over-heating). We have continued to develop a variety of new IPM series in line with the evolution of the IGBT chip. The "L Series" delivers loss reduction, thanks to the built-in CSTBT, and miniaturized packaging, while the "L1 Series" and "V1 Series" boast improved characteristics. The lineup also includes the "S1 Series", which is the successor to the "S-DASH SERVO Series".

Isolation TransformerOur Isolation Transformers give the stable and working performace and the high end material guarauntee the 0,98 Power Factor

You are angry about the prices from your energy consumption when in Harbor?  You know why?

May be your Shore Energy come in through your Shore Power Converter with an Power Factor of 0,7? And your Yacht is European build in 400V and 50Hz and you are in an European Berth?

In this case you need only an Isolation Transformer with a much better Power Factor for example in our Shore Power Unit 0,98. But this will help you only in Europe, in the Caribbean, Asia or USA you need an Shore Power Converter but here we can help also, our Converter with an Power Factor >0,94 save a lot of Money. And all together Transformer, Converter (on request with UPS) in our intelligent WWSP Plus III SHORE POWER UNIT will save Money all over the World and takes away headaches from Chief and Captain.  

And the best, we comply Class Society  requirements  with MΩ on In- and Outputs. No Ground faults.

5 Years Guarantee* and now also life time Guarantee* and we can offer an absolutely unbeatable Price.

You plan an refit please ask us

*with our yearly maintenance Plan you have lifetime 100% operational safety, no expensive repairs no dead times.
