How an uninterruptible power supply works

An uninterruptible power supply, or UPS, is a device used in businesses or homes to power devices when the main source of electricity has been turned off.

 

Typically used to protect computers, data centres or servers that would otherwise suffer data loss in the event of a power disruption, a UPS can range in size to protect a single computer to one that could power an entire building.

Typically, there are three different types of UPS devices:

  • Offline UPS

The most commonly found USP works by detecting any drops in the main electric current and automatically switches to UPS power. These are the most affordable type of UPS devices and they are the most commonly used in homes or small businesses.

  • Online UPS

This type of power supply is used mainly to convert AC to DC power, and vice-versa. This effectively filters out any disturbances in the power supply and also helps to prevent the electricity from tripping. They are the most expensive form of USP, and often used in larger office complexes.

  • Line Interactive UPS

This type of UPS functions both as a battery for when the main power is off and is also able to convert an AC current to DC. These are the costliest form of UPS, and are used mainly to secure corporate workstations, and large area server operations.

Why Every South African Should Own A USP

As of 2004 load shedding in the average South African home has increased exponentially, with power cuts becoming a daily experience in some parts of the country. As a business, sudden power cuts could result in severe data loss, lost productivity or possibility even damaged equipment. Having a USP as a business owner is a cost-effective and easy way to ensure that load shedding does not affect the day-to-day operation of your business.

The average South African home could experience load shedding every day, depending on the state of their local power grid. Small, affordable and easily installed UPS devices are available specifically for home-use, and go a long way toward preventing your personal computer from being damaged or having any personal data lost. Investing in solar or other renewable power will also help keep down your household costs.
