Safeguarding Samsung’s Liquid Crystal Display Facility with ABB’s PCS100 UPS-I Low Voltage Uninterruptible Power Supply (UPS) Unit

Samsung, one of the world’s leading manufacturers of electronics based in South Korea, invested $3 billion in constructing its liquid crystal display production facility in Suzhou, China. The connection units and major power equipment of the modern facility is protected from power disruptions through ABB’s power protection solution.

Overview of Samsung’s New Facility

Samsung’s huge production facility is situated at Suzhou Industrial Park in Jiangsu province, and it features the new 7.5 generation fabrication line that produces 100,000 glass substrates per month.

It is possible to divide each substrate into three 55” panels, six 46” panels and eight 42” panels, which will enable nearly 300,000 to 800,000 LCD TV’s to be produced per month. The facility was scheduled to be operational in early 2013. The new LCD line along with the existing LCD module production plant at Suzhou allows Samsung to set up the world’s largest integrated LCD production base in China.

By integrating ABB’s power protection solution to its new facility, Samsung has ensured protection of its production base against voltage sags, power failures and other electrical disruptions.

ABB’s Power Protection Solution

ABB’s power protection solution includes eight ABB PCS100 UPS-I low voltage uninterruptible power supply (UPS) units having a combined protection capacity of 16.5MVA.

The PCS100 UPS-I is a single conversion UPS consisting of an ultra-capacitor energy storage system. It is also integrated with a back-up inverter system to ensure uninterrupted operation of the downstream load in case of very deep voltage sags and short power outages.

The key features of the PCS100 UPS-I are:

  • Small footprint design
  • Ultra-fast transfer time of less than 2ms
  • Comprehensive customer support
  • Prolonged service life of 15 years versus three to five years of UPS batteries of other UPS batteries
  • Large low voltage power capacity of 16.5MVA
  • Short payback time of less than 12 months


Samsung also planned to install its latest $7 billion NAND flash plant in Xi‘an with 22 PCS100 UPS-I units. The facility, capable of producing 100,000 nanometer chips a month, was scheduled to be operational towards the end of 2013.

NAND chips find applications in solid-state drives, USB flash drives, memory cards and other data storage and transfer devices.

ABB has supplied more than 680MW of PCS100 power protection to flat panel LCD manufacturing and high tech semiconductor facilities.
