Emergency lighting inverters, collectively known as UPS (Uninterrupted Power Supply) is a common feature of residential and industrial technology in the modern day. Modern life has reached a point where an outage of electricity becomes headline news, thus creating a backup system is awarded the utmost importance. A few hours of lost power in a person´s home is known to causes restlessness. In industry, a loss of lights causes financial loss as well. With emergency lighting inverters darkness and grief can be avoided when electricity provided by power companies fail.
Principle of Operation in Electric Lighting Inverters
A UPS is powered by a DC battery which is ten converted to an alternating current (AC) supply which is used to powers homes, offices and factories etc. The AC supply can even be controlled to give the required level of current to power residential areas, typically 120/220 Volts. Although buildings require an AC supply because of the systems failure provided by power companies prevents AC current getting through the supply is taken from a DC current and subsequently converted.
A good inverter is normally considered to be 95-96 percent efficient, but the problem that lies in inversion is that sometimes a pure sine wave(AC wave) is not produced which leads to low power output. In applications such as cooling fans this can also cause more noise. Therefore the best emergency lighting systems are pure sine wave inverters.
Uses of Emergency Lighting Inverters
Emergency lighting inverters have a wide spread importance. Homes, office and public buildings such as hospitals, railway stations, theatres and restaurants all rely on lighting and power. In some work environments such as operating theaters, electricity is vital. Likewise sensitive areas like police stations, prisons and intelligence headquarters where a loss of power poses a security risk.
The blackout in New Delhi India hit the headlines recently because the failure of utility to supply electricity left 30 million people in the dark. Last year the power outage in California which left 1.5 million people without lights received heavy criticism from the media. Then there is the great North East blackout of 2003 in the USA that is known for being the longest amount of time that half the USA was blacked out.
It is incidents such as this where emergency lighting systems come to the rescue of people who rely on a flow of power. People may argue blackouts are few and far between, but eventually blackouts are inevitable. The repairs of the underground power lines and overhead cables, or the changing of a transformer during maintenance works can easily lead to a failure of the power grid and cause a power outage that lasts for hours.
Other Uses of Emergency Lighting Inverters
As well as lighting backup requirements, emergency lighting inverters can also be used to charge low power applications such as cell-phones, laptops/notebooks, run a microwave, electric iron together with other appliances that require an electricity supply from the mains.
High voltage applications such as generators can also be powered by UPS providing the voltage of the battery is high enough to support that application. In general, low voltage loads like the lights and life support machines are backed-up by emergency lighting inverters and quite literally could save lives.
