Things to Consider While Buying a Refurbished UPS A UPS serves as a power backup device for all connected appliances if the main power supply fails. It employs a rectifier-battery-inverter configuration that stores energy when power is available and feeds it during power outages and blackouts. A refurbished UPS system protects connected devices from sudden power outages, preventing data or functional loss of appliances. What exactly is a used UPS? Used UPSs, as the name implies, are generally devices that have been refurbished to serve a second life. The battery and other electronic equipment included in certified ones have a significantly longer life. When users increase their installed capacity, they must replace their current UPS with a higher rating. The existing UPS is rendered inoperable well before the end of its useful life. Such UPSs are discarded. How do used UPSs function? Their operation is identical to that of any other standard UPS. It always charges its battery by drawing power from the mains via a rectifier system. When the power goes out, the battery sends its stored energy to the connected appliances to keep them running temporarily. It gives users enough time to save data and properly shut down the apparatus or run the connected devices until the power comes back. What should you look for before purchasing a used UPS? Price: A refurbished UPS will vary depending on how much use the device has received. If it is still under warranty, the cost may be close to the original price. The number will decrease as the years of use and working conditions increase.
Power rating: The required output cannot exceed the power that the UPS is designed to provide. Before purchasing a refurbished UPS system, check the installed appliances and their total power rating. UPSs are classified into three types: standby UPSs, line-interactive UPSs, and online UPSs. Their cost varies accordingly. Offline UPSs are the most affordable and ideal for devices such as home computers, while line-interactive UPSs are slightly more expensive but provide faster switching. Online UPSs are the most expensive but are the most efficient and are suitable for sensitive installations. Backup time: The backup time required for the connected devices determines the size of the UPS. Purchase one with a long backup time so you can switch to another power mode or make other arrangements. Warranty: While many refurbished UPS systems do not come with a manufacturer warranty, they may include features such as extended support from the dealer. UPSs typically do not have extended warranties, but they function perfectly after that time. Characteristics of a used UPS • When compared to new UPSs, it is more economical and cost-effective. • When still under warranty, it performs exactly like a new device. • Because of the changes in their components, refurbished used UPSs have longer lives. • They come with full customer support when purchased from a certified dealer. Used UPS Applications • • • •
Ideal for home appliances that require backup power. When there is an initial revenue crunch, it can be used in data centres. Backup for digital display boards and televisions. For shorter periods of time, it can be used as an alternate source of power in industries.
