APC by Schneider Electric (formerly American Power Conversion Corporation) is a manufacturer of uninterruptible power supplies, electronics peripherals, and data center products.
APC was founded in 1981 by three MIT Lincoln Lab electronic power engineers. Originally, the engineers focused on solar power research and development. When government funding for their research dried up, APC shifted its focus to power protection by introducing its first UPS in 1984.
In 2007, Schneider Electric acquired APC and combined it with MGE UPS Systems to form Schneider Electric's Critical Power & Cooling Services Business Unit, which recorded 2007 revenue of $3.5 billion (EUR 2.4 billion) and employed 12,000 people worldwide. Until February 2007, when it was acquired, it had been a member of the S&P 500 list of the largest publicly traded companies in the United States. Schneider Electric, with 113,900 employees and operations in 102 countries, had 2008 annual sales of $26 billion (EUR 18.3 billion).
In 2011, APC by Schneider Electric became a product brand only, while the company was rebranded as the IT Business Unit of Schneider Electric.
