Marine power inverter power - Marine shore power - Pier Power

[Introduction] AF60 Series Terminal marine power inverter power equipment is designed for high temperature on board, shore pier, high humidity, high corrosion resistance, high load environment impact and other evil little use specially designed and manufactured power inverter power devices. Product features, performance, and many enhanced protection class extension products, play a central important components: IGBT power switching devices used in Germany and Japan's Mitsubishi ViewSonic grams module assembly; MPUs control US IT company specialized digital signal processing chip DSP: sine filtering system uses the inverter output isolation transformer boost, combined with our filtering technology, the module drive signal in parallel master-slave synchronization technology, three heat sealed cabin mobile technology, manufacturing air-conditioners bottom of the pipe cooling system technology and strict craft production. All commissioning works on the power panel is complete, installation and maintenance simple and reliable. It is with the domestic similar products with a reasonable structure, convenient shape Micron, handling, maintenance, operation. The key core parts are imported original, and the use of today's latest technology and the most advanced inverter technology, components (modules) safe and reliable, non-polluting, high reliability, high intelligence, high-capacity. 21 represents the technology trends of the actual shore power supply. All PCB circuit board using the layer curing process; sine filter, the output transformer vacuum impregnation with the overall high temperature protective insulating paint and spray paint handling, with high levels of insulation and protection; cabinet with spray. Protection class IP22, installed in our production of mobile tanks, the overall protection class IP55, suitable for outdoor and frequent movement of the overall situation and poor working conditions. Single power capacity 100KVA-1000KVA. [Features] ◆ all power inverter are used in the form of AC-DC-AC inverter, the rectifier is not controlled by a diode rectifier will enter the grid side harmonic currents, so that any variable frequency power supply will be on the grid have some The harmonic current emissions, especially in the case of a large power capacity must be suppressed to the input harmonic current. Frequency power usually six-pulse rectifier input current total harmonic distortion THDi 65%, prone to impact on the grid other devices. Tebian designed and manufactured using 12-pulse input rectifier transformer and 12-pulse thyristor rectifier air, eliminate 11 times less input harmonic current, the total input harmonic current THDi≤15%, will not produce harmonics on the grid wave interference, are green products. ◆ use our power against shock load characteristics and specially designed for the development of production of the inverter output filter technology and a specially designed isolation transformer, thus greatly reducing the output impedance of the variable frequency power supply unit to handle large current impact and band ability to meet the complex. ◆ Since the device appears to be installed in the outdoor pier shore protection and cooling system is particularly important, therefore, to move heat sealed compartment. Regardless frequency power device when used in the operation (running) Shihai in standby, equipment cabin are completely sealed, from the protection class IP55. Ensuring power inverter equipment from outdoor dust, corrosive effects of moisture. Frequency power device and the heat generated by all the equipment cabin saw the heat radiating from the air-conditioning. The heat generated by the power supply frequency power inverter power capacity computing configurations adjustable unit, air conditioner connected by pipeline to the bottom air-conditioning cooling system, forming apparatus and equipment cabin space overall cooling system. [Key performance indicators] ◆ rated input voltage: three-phase input power supply 380V / 50Hz commercial power supply (AC voltage fluctuation range allowed by the 323-528V) ◆ Rated output voltage: Output voltage according to user requirements, provide a variety of single / three phase voltage level; ◆ Rated output frequency: 60Hz / 50Hz (can be any conversion) or 400Hz. ◆ rated frequency accuracy and stability: output frequency error = 0.01Hz; stability
