Your data and computer systems are important to you and your business. Power is the lifeblood of your data center, and your IT equipment is designed to be supplied with a steady flow.So UPS (uninterruptible power supply )systems are a critical component of your data center, whether you’re running just a couple computers or numerous servers. UPS systems are not designed equally, and choos...

A UPS(uninterruptible power system) typically provides up to 30minutes-2hours of backup power. In other words, UPS is not intended to keep your computer equipment running during a blackout, but it does give you the opportunity to safely save whatever you are working on and properly shut everything down. Unfortunately, the battery will not retain a charge forever, and there are many mista...

What are the power issues
- 2019-05-27 15:28:29
- admin
There are various power problems that a uninterruptible power supply(UPS) will correct depending on topology and functionality incorporated by the manufacturer. They are as follows: ●Power outage ●Voltage sag – short term under-voltage ●Brownout – Low voltages for an extended period of time ●Over voltage – Increased voltages for an extended period of time. ●Voltage Surge – short term over-voltage ...

Single-phase power
- 2019-06-18 15:51:24
- admin
In electrical engineering, single-phase electric power refers to the distribution of alternating current electric power using a system in which all the voltages of the power supply vary in unison. Single-phase distribution is used when loads are mostly lighting and heating, with few small electric motors. Single-phase electricity is what you have in your house. In general, household electrical sup...

The voltage surge and its impact on computer equipment
- 2019-06-18 15:52:44
- admin
When powering off high-current equipment or a group of high load equipment connected to a single power source, an inertial voltage surge may be generated during power transmission. Most computers or precision equipment feature a certain range of operational voltage that accommodates such a situation. However, if the voltage surge is greater than the tolerance settings, some equipment or components...

How much UPS capacity do you need?
- 2020-05-18 16:22:50
- admin
You can estimate your UPS capacity requirement by totaling the requirements of all the equipment you plan to connect to the online UPS . You should refer to the equipment manufacturer's documentation to find the wattage. If you can't find any printed or online documentation, refer to the equipment nameplate. If your equipment lists its power requirements in amps, multiply the number of amps by the...

Three Phase Power
- 2019-06-18 15:55:49
- admin
As well being the most efficient way to distribute power over long distances, three-phase power also enables industrial equipment to operate more efficiently. Three-phase power is characterised by three single-phase waves that are offset in their phase angle by 120 degrees, or one third of the sine wave period (see Figure 1). Three-phase voltage can be measured from each phase to neutral or from o...

What kinds of batteries are used in a UPS?
- 2019-06-18 15:56:14
- admin
Most commercially available uninterruptible power supply (UPS system) use sealed lead-acid batteries that are water-and maintenance-free. The energy is generated by chemical reactions in a paste-like electrolyte. For most consumers, these batteries are not only easy to use and maintain but also simple to replace when necessary.
