The Power Outage Problem Alternative Power Supply

Introduction Power supply is a gadget that delivers electrical energy to electronic loads. The power supply that is required in this project is an uninterrupted type, which provides emergency power when the input source fails. This power supply provides immediate protection from input power failure.Advertising We will write a custom proposal sample on The Power Outage Problem: Alternative Power Supply specifically for you for only $16.05 $11/page Learn More Besides preventing discontinuation of the test if power outage occurs, uninterrupted power supply can also be used to protect the test equipment from damage or data loss. The purpose of this proposal is to recommend the most appropriate alternative power supply to solve the power outage problem. UPS Power Supply UPS power supply comes in two forms that is, standby and online. A standby type reacts only when a power outage occurs. Consequently, it must come with a particular circuitry that promptly con verts to a power backup. An online power supply does not end its supply of power to the equipment. As such, it does not need to respond promptly when a power outage occurs. When the source of power discontinues, the devise’s batteries continues to supply the equipment with power. This type of power supply is the most preferable, though more expensive (Rashd 79). Considerations While Choosing the Power Backups When choosing one of these power backups, it is important to consider factors such as the amount of time the UPS battery sustains power, whether it provides any warning signal to the server when on standby and whether it has a power-conditioning feature that can trap the inward bound passing noise. Furthermore other factors should be considered such as how the battery degrades over time, the life span of the battery, whether it provides warning signs whenever the battery’s backup power ceases to function and when the batteries need replacement. It is also very imp ortant to consider the power requirement of the equipment that will be attached to the power UPS. For example, server installation considerations can be based on the devices that are added to it, such as CPU, monitor, wiring centers and concentrator units (Rashd 98).Advertising Looking for proposal on engineering?

The power equipment on which the UPS is attached should be added up then a UPS that accommodates such a load should be chosen. First, the ampere rating on each device that is to be attached should be obtained then the rating multiplied by the voltage. The values for each device are then added up and a UPS, which can accommodate at least 20 percent above that load, is chosen. Power supply for each chamber Each of the chambers, including the deepfreeze and oven, should have their own power supply hence two power supplies are required. Although using one power supply can be more economical, the unique requirement of each chamber makes it necessary to differentiate the power supplies (Rashd 68). Lease or buy decision To decide whether it will be more economical to purchase or lease the power supplies, we shall have a practicable analysis. In this case, the power supply cost $570 (including incidental cost). If leased, however, the installment payments will be $225 per annum for five years. The installments are inclusive of the maintenance and service costs. The salvage value of the power supply after five years is $45. The company uses straight-line method of depreciation. If the power supply were bought, service and maintenance charges would be an average of $61.2 per annum. The cost of capital is 18%. Corporate tax is 40%. The cost analysis to show whether the company should buy or lease the equipment is performed as follows: Present Value of Interest PaymentAdvertising We will write a custom proposal sample on The Power Outage Problem: Alternative Power Supply specifically for you for only $16.05 $11/page Learn More The purchase decision is better (Ogilvie 94). Conclusion and recommendation Installation of a power supply is essential as it will prevent interruptions of the tests hence avoid the penalty of $1000 per day, which is considerably a huge loss. Even though it may be argued that the cost of buying or leasing the power supply is significant and less efficient, it should be borne in mind that a technician cannot prevent the power outage and cannot prevent test dilapidation. Hence, hiring technicians to operate the site at night can be better. Therefore, it is recommended that the power supplies be purchased to remedy the situation. Works Cited Ogilvie, John.
