What is a UPS Device?

UPS is short for "uninterruptible power supply" and describes an electronic device used to protect electronics from unstable power situations and power outages. The device usually includes battery power that allows a transfer time after the grid power has switched off, so that you can safely shut down electronics and security systems.

They also include automatic voltage regulation and surge protection, which will ensure surges and spikes in the electricity coming from the power grid don't fry your equipment. In South Africa, many business owners have begun to rely on online UPS systems to safeguard their electronic equipment from the effects of load shedding.


How Uninterruptible Power Supply Devices Work

The device gets plugged into the wall socket, connecting it to the grid, and then devices like computers, laptops, screens, and Wi-Fi routers are plugged into the UPS. You can plug in any electronic device into the UPS that draws a lower voltage than the capacity of the device. The UPS receives incoming voltage from the utility company (e.g. Eskom).

The incoming utility power flows through an internal converter and regulator that stabilises the flow. Any excess voltage is redirected. The power connected equipment receives comes from the UPS battery within the device after it has been stabilised. This battery power offers a stable flow of power and protection from power anomalies.

How Long Do UPS Devices Last?

Different uninterruptible power sources last for differing lengths of time. The size of the UPS battery and the load size it can bear influence how long it lasts. It's also important to note what you plug into it. The battery run time will be lower when you plug in an LCD display, for example, than when you plug in a phone charger.

Compare device capacity and consider the power output required by your electrical devices. You can look at your power consumption and the voltage needs of connected devices compared to what the battery capacity of the UPS is.


What Are the Benefits of Using a Uninterruptible Power Supply Devices?


  1. Keeps IT equipment and computer systems safe and operational
  2. Extends the lifespan of your electronics and appliances by protecting them from damage caused by unstable voltage conditions
  3. Allows time for mission-critical system shutdowns during power cuts by supplying short-term power to equipment
  4. Provides battery backup power when load shedding strikes so you can keep working
  5. Allows time for generators to start or backup power to kick in if power failure occurs
  6. Lowers business interruption costs because work can continue as usual even if the incoming power from the utility company fails

The Virtual Sense Range of UPS Devices

Whether you need a device that gives you battery runtime for an extended period or a back-up source of power to allow for safe shutdown of equipment, we have an uninterrupted power supply device for you. Discover the basic features of different types of UPS devices available from Virtual Sense Power:


Line-Interactive UPS Systems (Pure Sine Wave Units)

A line-interactive UPS must always be plugged in to the wall. When the power flow is normal, it flows from the wall socket, through the inverter within line-interactive units, to charge the UPS battery. When there is a power cut, the battery power kicks in and supplies power. 

Line-interactive UPS technology is usually more affordable than online ups systems with double conversion technology. It's useful for protecting consumer electronics and office equipment from power surges, voltage sags, voltage surges, and blackouts. However, it doesn't protect the device from frequency variation and electrical line noise.

An online uninterruptible power supply is a strong choice for superior protection from unstable voltage conditions such as surges due to lightning. It uses a double conversion method to power the plugged in equipment.

It may be a more expensive option, but this expense quickly becomes worthwhile when it performs without a hitch to protect your electrical equipment from surges. Online UPS systems also tend to last longer.

Are you looking for an alternative power supply that offers you a higher quality of power and stability in South Africa's uncertain power environment? You can say goodbye to the perils of inconsistent power conditions with premium power protection from Virtual Sense!
