Why do you need a UPS? A Universal or Uninterrupted Power Supply protects your equipment against the following power related issues:
.
.
- Power Surges - When the voltage temporarily increases
- Power Drops - When the voltage temporarily drops
- Power Blackouts - When the power supply is cut off
.
.
Each of these situations can potentially crash or turn off your equipment. The potential loss to your business or company can be catastrophic. For this reason, UPS systems are the right safeguard.
.
.
There are Three types of UPS system that you can currently purchase.
The first type is the Offline or Standby UPS. This is the simplest type of UPS system available. The Standby system allows the computer to run off the mains power supply until there is one of the three issues mentioned above. When it detects this, it reacts and switches to its battery supply until the threat to the supply has been removed.

The second type is the Line Interactive UPS An affordable way of protecting against 5 main types of power problems, power failure, sags, surges, brown outs and line noise. Change over to battery supply is done in milli-seconds ideal for budget conscious users Suitable IT Applications: Office environment PCs, workstations, small servers, rackmount applications and network devices. Similar in operation to the Off-Line system provides basic power protection. This design offers low-grade voltage regulation by bumping the mains voltage up or down, typically known as buck and boost. This feature: Improves the quality of ac mains to the supported load, reduces the number of transfers to and from battery mode, reduces the number brief power interruptions to the load when switching to and from battery mode, thus improving the life expectancy of the battery.

The third type of UPS system is the On-line Continuous UPS. The most dependable solution to your power protection needs. Online UPS provides against 9 of the most common power problems: Power failure, sags and surges, Brownouts, line noise, Spikes, frequency variations, switching transients and harmonic distortion. Suitable IT Applications: Critical servers, small networks, routers, hubs, Server rooms, networks, Data centres, Server farms, Communication and broadcasting, Offshore, Marine, Medical, and Industrial Applications. Best technology for use with generators. This option offers the highest level of protection and reliability. The inverter is always on and supplies the supported load with clean regulated power. All incoming power is converted to dc via the rectifier and then the inverter converts back to ac No interruptions to the load when switching to and from battery mode. The incoming power is always fully conditioned. Constant voltage and frequency regulation means far less switching to and from battery, which in turn means conserving the battery life and increasing the reliability of the UPS.

Standby UPS is usually used in homes and by small businesses. Larger organisations or companies that need a very stable and consistent source of secondary power (in the case of any of the above three power issues) use Continuous UPS systems. Standby systems tend to be cheaper than the Continuous UPS systems, but Continuous systems are the more reliable type of UPS. If you have a room full of servers, you'd need to maintain a constant supply of electricity, even the slightest break in power could harm business or lives. A continuous UPS is required for this type of user.
.
.
The type of UPS system that you choose depends upon the demands that you need to place upon it. Whilst the cheaper UPS Standby systems may be cost effective, the short power delay involved in the switchover from mains to battery may cause some disruption to your PC or Telecoms systems. There is a small chance that the fraction of time it takes to switchover might cause some kind of data loss, which may result in loss of business, a lapse in security or danger to your employees.
.
.
However, even with the best Continuous UPS systems, the battery will not last forever. It's important to have a UPS that won't just turn itself off when the battery reaches nil. If the data on your PC is vital to your business, then it's worth investing in the type of UPS that will also safely store your important data and turn off the network operating system before the battery is empty. This protects your network and the vital data on your machines.
