Uninterruptible power supply

with the potential of environmental disasters it is prudent to have backup systems so that your site can maintain continuity (Pagoria, 2004). Should the power ever go off in the building backup devices must be present in order to ensure that normal operations are restored ASAP. There are two devices that can restore power to equipment quickly: an uninterruptable power supply (UPS) and a power generator (Pagoria, 2004). Generators can be set to automatically start up in case of power outages and can be used for general building functions, such as AC and lighting. The UPS is used primarily for the supplying of electricity to the company computer boxes or servers. If a company server loses power, and there is no backup in place, the server will shut down resulting in loss of use and loss of productivity. However, with a UPS, if the electricity to the server is lost, the UPS will take over. The UPS battery source will provide the needed electricity. Although the supply of electricity is limited, it generally provides enough time to keep the server running until the electricity is restored. Some UPS units will sound an alarm to alert the IT administrator, to safely shut down the computer box and avoid a hard shut down. Another function of the UPS is to intercept power spikes and prevent a spike form reaching computer equipment. Power spikes can be dangerous to computer equipment and result in costly damage (Pagoria, 2004). Fire is an ever present danger when there are high…

The real danger of blackouts and brownouts is the unexpected computer shutdown. Operating systems are complex and they must go through a “Shutdown Sequence.” An unexpected loss of electricity can interrupt important threads, and leave your computer in an inoperable state. The biggest certain are the computer files because you’ll have to reboot the whole computer after that, losing those files. When it comes to frequent outages and surges, you lose the physical lifespan of a hard drive. Including…

problem that can find itself label in such a way are power outages as this is a problem but not one likely to be viewed as overly serious as they do not happen often and when they do they tend to be brief. This issue along with what types of problems and solutions to each is what will be focused on for this…

Welding can be very fun and empowering. Watching the sparks fly from the metals, and seeing the world’s strongest metals be made into what a welder wants for it to become. Welding requires hard work and a considerable amount of practice. It requires hard work, dedication, and concentration. If one welder does not pay attention to their work it could result in a considerable amount of damage to yourself and even others. Welding is the binding together of metals using mechanical machines…

Welding There are 5 main types of welding process commonly used in industrial welding. They are; Gas Metal Arc Welding, oxy acetylene, Gas Tungsten arc welding, flux core, and Shielded metal arc welding. All welding procedures are important and useful for a variety of things. Welding is the process by which two or more pieces of metal are joined or metal has material added to it to fill a hole. Welding process work by heating the base metal, or the material being on, to a liquid state. They…

b. When measuring the resistance value with the Avo 8, possible reasons for varience include a parallax error (not looking at the reading from directly above the meter), a reading error due to less divisions when measuring resistance, or the device not being properly zeroed. When measuring current, there are also fewer division, parallax is still a potential issue, and finally, incorrect zeroing of the meter. Voltage has an additional error, the loading of the meter itself. Alongside this issue,…

1762-IF4 is an Allen Bradley MicroLogix 1200 System with 4 Channel Current/Voltage Analog Input Module. It has a dimension of 90 x 87 x 40.4 mm. It has Delta-Sigma converter and 4 differential (bipolar) inputs. It’s analog operating voltage range is -10 – 10 V DC normal and -10.5 – 10.5 V DC full scale. It’s analog operating current range is 4 – 20 mA normal and -21 – 21 mA full scale. It converts the analog input up to the full-scale range. It enhances the functionality of MicroLogix 1200…

in application. where no isolation and high output current with low ripple. An No isolation DC/DC converter Fig.1.1 shows the step-down DC/DC converter. When switch M is on for the duration of dTs, power is transferred from source to load and filter inductor L is charged. When switch M is off for a duration (1-d)Ts, the diode D becomes forward-biased and forms a conduction path for the filter inductor current. The voltage across the filter inductor is the reverse of the output voltage. By using…
