What is an uninterruptible power supply?
An uninterruptible power supply, or UPS, offers guaranteed power protection for connected electronics.When power is interrupted or fluctuates outside safe levels, a UPS will instantly provide clean backup power and surge protection to plugged in sensitive equipment.
Why do you need a UPS in your home or business?
Home — The electronic devices you rely on every day for communication, security, and entertainment are at risk of damage and disconnect due to unexpected blackouts, voltage fluctuations, and other power disruptions.
A UPS will provide backup power and protection for a variety of electronic devices, including:
• Wireless networking equipment (routers and modems)
• Security systems
• Gaming consoles
• Mobile devices
Business — Downtime caused by power outages is frustrating for anyone, but can be financially crippling for a business or organization. Every year billions of dollars are lost due to the downtime caused by power disruptions that a proper UPS setup could have rectified.
What size UPS do you need?
Electronics have both maximum watt ratings and maximum volt-ampere (VA) ratings; and neither the watt nor the VA rating of a UPS may be exceeded by the attached equipment. Watts measure the real power drawn by the equipment, while VAs are the product of the voltage applied to the equipment times the current drawn by the equipment. What you really need to know is that for electronics such as computers and UPSs, watt and VA ratings can differ significantly; with the VA rating always being equal to or larger than the watt rating. The ratio of the watts to VA is called the “power factor” and is expressed either as a number (i.e., 0.8) or a percentage (i.e., 80%). This power factor is what really matters when sizing a UPS for your specific requirements. Typically, it is recommended that you choose a UPS with an Output Watt Capacity 20 – 25% higher than the total power drawn by the attached equipment.
