IP66 Marine frequency converter (380V or 400V or 10KV) 400KVA-4000KVA

Marine frequency converter(380V or 400V or 10KV ) are specially used in ports, dockyard fitting-out berth, shipbuilding,shiprepairing and oil drilling platforms,which is made by world-class technology of ours.

Characteristics

Introduction

Marine frequency converters are specially used in ports, dockyard fitting-out berth, ships and ocean drilling platforms with outdoor harsh environments which need outdoor frequency conversion variables with high reliability of power supply. This series of products adopt full sealed three layers of insulation pipeline with full air conditioning circulation protection. Inside of equipment environment is completely isolation with the outside world. Equipment tank protection level IP66, air conditioning system is level IP56, fully meet the shore wharf, ships and drilling platforms with any harsh outdoor environments. A complete set of equipment in accordance with the standard container box shape design, easy to transport and move often. 

Feature

●Using the full sealed air conditioning cooling system with three insulation layer tank to ensure that the equipment is under good protection.

●Adopting the latest instantaneous voltage waveform control technology, output voltage fluctuation≤0.5V,when 100% load, the output voltage fluctuation less than 3% and recover to the rated output voltage value in 0.5 wave cycle.

●Adopting technology of pure sine inverter output filter. Reduce the output impedance of the sinusoidal filter and improve the quality of the output power.

●Driven by our module with signal master-slave synchronization parallel technology. Which can realize parallel working of many shore variable power equipments without current circulation interference.

●Using the power switching devices which is made by Germany, DSP core is made by USA with 5Mhz optical fiber driver transmission mode. The inverter modulation method adopts the latest SVPWM space vector pulse width modulation.
