An uninterruptible power supply or
uninterruptible power source (UPS) is an electrical apparatus that provides
emergency power to a load when the input power source or mains power fails.
During several months, with the efforts of the expert
personnel of Fajr Petrochemical Plant, and with the cooperation of a domestic
knowledge-based company, control and feeding cards for the UPS system of the
water treatment unit 2 of the complex, were resorted at with the lowest cost.
The system was seriously damaged in an incident
last September and the plant's experts started off restoring it despite all the
complexities of the system.
The electric cards used in the system were either
outdated or no longer produced or were targeted by international sanctions. Therefore,
the plant's management decided to put on agenda their domestic production.
For the design and construction of electronic
cards, advanced reverse engineering techniques were used, and Fajr
Petrochemical Company is not only able to supply its internal demand for the item,
but it is also ready to transfer its experiences as technical advice to other
companies.
