Low voltage shore power supply

BOS large power inverter modules contains IGBT 、SMPS、radiator、electrolysis、absorptance ,capacitance ,driver board,copper plate etc. The modules adopt IGBT inverter technology, high reliability, small capacity, large making material savings, light in weight, move easily; The match is the best technical Parameters, reducing the wire inductors. In structural design, it get the switch power and the module M57962AL together, can save even more space and bring ability become more strong, it will reduce 50% cost than abroad similar products. It enhance system reliability, and a more evenly distributed, more compact structure, elegant and beautiful.


Low voltage shore power supply

1. Group modular design, high energy economy, reliability

 The rectifier inverter section of the ports shore power supply adopts modular design, small size, light weight and high efficiency. The inverter part with every 800KVA as a inverter unit, which can control a host of automatic unit working in parallel as required and which parts automatically exit jobs. This allows "N + 1" is the best option. Simultaneous failure of a cell will not affect the all system output (When fault, the unit automatically exit system), which can greatly improve system reliability.

2. Super overload ability

Inverter part designed specially for the high-power motor load, with small voltage transients, shorter recovery time, and strong start capability. And a unique current limiting technology, which greatly improves the impact resistance of the power supply.

3.Intuitive display, easy to operate

Man-machine interface with large touch screen plus emergency stop button, clear display interface, friendly, intuitive, with remote monitoring. All the display data can be displaied or stored by the remote monitoring computer.

4.Simple structure, easy maintenance

Ports shore power supply with a breakthrough design, implement standardized production; internal circuit modular, easy to install, simple to maintain. System design completely with our own technology and the basic devices are well-known foreign brands with stable and reliable feature.For the purchasing channels is very smoothly,the procurement cycle is short, and maintenance and repaire with low cost , timely and efficient after-sales response.

5.The unique line voltage compensation

Solve the problems of the far distance from the shore power to the load andthe wiring length of a line voltage dropping big .You can set line voltage compensation to ensure that the load voltage input terminal to meet the requirements.

6.Complete protection

Overvoltage, undervoltage, loss of voltage, over current, short circuit, overheating, phase, voltage surge snubber, ground instantaneous current limiting protection, and has a number of failures recorded query parameters.

7.High output efficiency

Companies with high quality, low power transformer, combined with the unique design of the individual output filter system, so that the overall output efficiency is greatly improved.

8. anti-interference ability

Drive control using optical fiber, the system has strong anti-electromagnetic interference capability and reliability.
