Delta UPS for escorting LED sapphire chip companies L'Assurex

The purpose of the UPS power supply system is to provide high quality uninterruptible power supply to the electrical equipment on the production line through the UPS power supply system, so as to ensure the normal operation of the electrical equipment. Recently, the delta NT series UPS products with its excellent product quality and perfect and Dentsu solutions offered by the successful bidder, a Sapphire Technology Ltd, to provide protection for the company's factory in two production line production equipment normal power supply.

The Sapphire Technology Ltd is a newly established sapphire LED chip production of large enterprises, its advanced industrial production equipment and ancillary equipment for the quality of power supply network is very strict. The crystal furnace rated power is 90KV, the maximum current is 139A; the total number is about 90 units, each production line of 30 units. The furnace requirements on power quality is very high, the UPS output voltage stability is less than 1%; the maximum furnace is heated to 2000 DEG C, heated by DC electromagnetic excitation; power furnace is a rectifier equipment, it will produce a large number of harmonic current, with different conditions, the power factor is 0.2--0.8; in addition, the project UPS backup delay time needed by 5 minutes; to have some redundancy, to ensure the security of high reliable electricity.

The load characteristics of the furnace equipment can be equivalent to the rectifier equipment. Therefore, UPS selection, the selection of anti harmonic current capacity, overload capacity, high load impact resistance with frequency isolation transformer UPS device; output power factor UPS equipment should be matched with the load, so the output of the UPS ability to make full use of the maximum output voltage stability; UPS high, UPS should have sufficient margin to be able to adapt to the load, low power factor and harmonic current is large; in addition, due to the importance of the furnace production line, it should be the choice of power supply scheme with redundancy.

The load analysis of the project based on the Dentsu recommend to customers the delta NT series UPS, this UPS single power is 20KVA to 800KVA, is designed to operate in large industrial and mining enterprises of high reliable industrial UPS. The project uses Delta NT500KVAUPS composed of 4+1 parallel redundant power supply system, providing power supply for 15 furnace equipment. To ensure that a UPS redundant backup to ensure the stability and reliability of the load power supply. The battery is used Dentsu battery. Each UPS is equipped with 3 sets of 200AH/12V batteries, which can meet the load time of 5 minutes. A set of 4+1UPS system, a total of 15 sets of batteries to be configured.

The overall Dentsu solutions offered by the normal operation of the Sapphire Technology Ltd's production equipment has been a strong guarantee, won the highly recognized by users. Delta NT series is currently the UPS UPS mainframe market in the classic, the advanced IGBT switching frequency sinusoidal PWM technology design, and the power quality is good, high efficiency, small heat loss, low noise, small volume, long life and other advantages, are other brands do not have this series of products, since its launch will be of concern, has accumulated a large number of loyal users in many industry applications, a reliable choice of enterprise security dynamic stability.
