Our first research and development of uninterruptible power supplies date back to the 1950s. We completed a prototype in 1954 and exhibited it in various venues.
However, the necessity for a consistent power source can be traced back to the early 20th century. As industries grew and technology progressed, the need for reliable power became paramount. Early
One of the early pioneers in the development of UPS technology was Alan Charlesborn, who in 1934 received a patent for an “Apparatus for Maintaining an Electric Circuit.” His invention
The first commercial UPS systems were introduced to address the growing need for reliable power in critical applications, such as data centres and early computing environments.
The concept of continuous power supply emerged in the early 1900s in the United States. The first UPS system was introduced by Emerson in Los Angeles in 1903, marking the inception of power...
An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails.
The very first UPSs consisted of a flywheel that would provide short bursts of backup power. This rotary system was inefficient and wouldn''t have been able to support modern servers and databanks. After

An uninterruptible power supply (UPS) or uninterruptible power source is an electrical apparatus that provides emergency power to a load when the input power source or mains power fails. A UPS differs from an auxiliary or emergency power system or standby generator in that it will provide near-instantaneous protection from input power interruptions, by supplying energy stored in batteries, supercapacitors, or flywheels. T
Who Invented the Uninterruptible Power Supply? The uninterruptible power supply (UPS) was created by John J. Hanley. Passenger trains were something he was into back in his day. To ensure the
The uninterruptible power supply has an interesting history and has changed since its first introduction in 1934. Read on to learn more about the history of the uninterruptible power supply.
