What Is On-line UPS (Uninterruptible Power Supply) And How Does It Work?

As a society that requires electricity to do nearly everything, power interruptions are devastating to virtually any business or individual. From driving electric vehicles to using a cell phone, manufacturing all manner of products to using PC’s, interruptions are dreadful. Caused by lightning strikes, hurricanes, snowstorms or alternatively power plant tripping or cars running into power line poles, downtime can last a few moments to multiple hours. The impact for businesses is magnified further. Downtime causes personnel safety issues, equipment failures, production losses, defect increases, and overall lost commercial value.

What Power Problems Does On-line UPS (Uninterruptible Power Supply) Solve?

The S&C 2020 State of Commercial and Industrial Power Reliability Report found that a typical outage cost 20% of C&I companies at least $100,000 over the past year. Stay in control with on-line UPS (Uninterruptible Power Supply) that can help your business avoid electrical interruptions altogether. In general, a UPS is a device that can provide emergency power to a load when the main source of power fails near-instantaneously. UPS can also correct common utility power problems including voltage spikes and sags, frequency instability, harmonic distortion, and general electrical noise. A UPS combined with a longer lasting battery can also address utility power outages and sustained voltage reductions.

How Many Types Of UPS Are There And What Type Does Demand Power (“DPGI”) Use?

There are generally three types of UPS. These are on-line, line-interactive, and standby. On-line UPS is the most common UPS used for power protection in data centres and other businesses with sensitive equipment. On-line UPS uses a double conversion method to accept AC power from the utility, rectifying (AC-DC) the power to a DC bus, and then inverting (DC-AC) the power back to AC. Also attached to the DC bus would be a battery that would always be connected so that no power switches or outages occur. On-line UPS also comprise static switches and a manual bypass for safety and maintenance operations. This method of on-line double conversion is considered an “electrical firewall” to utility power; similar to a network firewall that prevents disturbances from the Internet into your computer.

Generally on-line UPS are IEC 62040-002 and UL1778 certified which means that they are the highest quality equipment providing the best protection. Moreover, the UPS cannot back-feed electricity into the utility grid. These advantages mean that not only will you get clean power; the UPS device cannot harm the utility lines or safety of utility operators.
