The Uninterrupted Power Supply is an electrical apparutus that provides emergency power to a load when the other source of power fails to work or be functional. The on-battery run-time of most uninterruptible power sources is relatively short (only a few minutes) but sufficient to start a standby power source or properly shut down the protected equipment. It is a type of continual power system. A UPS is typically used to protect hardware such as computers, data centers, telecommunication equipment or other electrical equipment where an unexpected power disruption could cause injuries, fatalities, serious business disruption or data loss.
UPS units range in size from units designed to protect a single computer without a video monitor (around 200 volt-ampere rating) to large units powering entire data centers or buildings.
This UPS offers only the very basic kind of features as compared to other variants. The protected equipment is normally connected directly to incoming utility power. When the incoming voltage falls below or rises above a predetermined level the SPS turns on its internal DC-AC inverter circuitry, which is powered from an internal storage battery. The UPS then mechanically switches the connected equipment on to its DC-AC inverter output. The switch-over time can be as long as 25 milliseconds depending on the amount of time it takes the standby UPS to detect the lost utility voltage.
his type of UPS is able to tolerate continuous undervoltage brownouts and overvoltage surges without consuming the limited reserve battery power. It instead compensates by automatically selecting different power taps on the autotransformer. Depending on the design, changing the autotransformer tap can cause a very brief output power disruption, which may cause UPSs equipped with a power-loss alarm to "chirp" for a moment.
This has become popular even in the cheapest UPSs because it takes advantage of components already included. The main 50/60 Hz transformer used to convert between line voltage and battery voltage needs to provide two slightly different turns ratios: One to convert the battery output voltage (typically a multiple of 12 V) to line voltage, and a second one to convert the line voltage to a slightly higher battery charging voltage (such as a multiple of 14 V). The difference between the two voltages is because charging a battery requires a delta voltage (up to 13–14 V for charging a 12 V battery).
Furthermore, it is easier to do the switching on the line-voltage side of the transformer because of the lower currents on that side. To gain the buck/boost feature, all that is required is two separate switches so that the AC input can be connected to one of the two primary taps, while the load is connected to the other, thus using the main transformer's primary windings as an autotransformer. The battery can still be charged while "bucking" an overvoltage, but while "boosting" an undervoltage, the transformer output is too low to charge the batteries. Autotransformers can be engineered to cover a wide range of varying input voltages, but this requires more taps and increases complexity, and expense of the UPS. It is common for the autotransformer to cover a range only from about 90 V to 140 V for 120 V power, and then switch to battery if the voltage goes much higher or lower than that range.
The online UPS is ideal for environments where electrical isolation is necessary or for equipment that is very sensitive to power fluctuations. Although it was at one time reserved for very large installations of 10 kW or more, advances in technology have now permitted it to be available as a common consumer device, supplying 500 W or less.
The online UPS may be necessary when the power environment is "noisy", when utility power sags, outages and other anomalies are frequent, when protection of sensitive IT equipment loads is required, or when operation from an extended-run backup generator is necessary. The basic technology of the online UPS is the same as in a standby or line-interactive UPS.
However it typically costs much more, due to it having a much greater current AC-to-DC battery-charger/rectifier, and with the rectifier and inverter designed to run continuously with improved cooling systems. It is called a double-conversion UPS due to the rectifier directly driving the inverter, even when powered from normal AC current.
The company Amara Raja is a subsidiary of the Amara Raja group that is a very well known brand in the Indian markets. They are known to be selling these UPS for quite some time and have also captured a good market when it comes to selling these.
Genus power is one of the best companies in the indian markets to manufacture UPS. They are known to have the top most R and D. It currently has five manufacturing facilities in India.
What gives the firm such manufacturing prowess is its eight manufacturing facilities located in in Chennai, Parwanoo, Pondicherry and Maphe. It can defintely be added to the list of companies that are doin g really well in terms oftheir sales and manufacturing. The profits are running in.
Delta Power is a subsidiary of Thai firm Delta Electronics with two manufacturing and two R&D facilities in India. Among the major power storage systems offered by the firm are UPS systems, and other renewable energy products.
True Power was established in 1993 and has made a name the top UPS manufacturers in India courtesy of progressive vision and zeal for technological innovations. The firm has a manufacturing facility located in Parwanoo along with a solid R&D department. So, there you have it. These top 10 UPS manufacturers are only among a host of other firms that are contributing to the energy storage and power-backup market in India.
Leading the UPS race in India is Luminous Power Technologies courtesy of its broad portfolio of energy backup solutions that include UPS, and other batteries for certain solar applications. Luminous has seven manufacturing plants spread out in the states of Himachal Pradesh and Maharashtra. Power is an important topic, especially, in a land as big and as diverse in India. If you really see, the issue of power and energy in India can be highly divisive- in the way that for a person sitting in Lutyens Delhi, and for a person from the countryside, the energy requirement per day is hugely disproportionate.
