What is a UPS Device?

UPS is short for "uninterruptible power supply" and describes an electronic device used to protect electronics from unstable electricity situations and brown outs. UPS devices are essential for ensuring uninterrupted power supply during long periods of electrical outages or fluctuations. UPS power supply devices are designed to seamlessly take over when utility power fails, ensuring uninterrupted electricity for critical systems and equipment. These devices offer robust power protection, safeguarding sensitive electronics from voltage fluctuations and outages. Power failure can be catastrophic when it comes to electronic devices. The device usually includes battery power that allows a transfer time after the grid electricity has switched off, so that you can safely shut down electronics and security systems.



UPS devices are invaluable tools in a world where power outages and sudden electrical failures can disrupt our daily lives and essential services. These devices act as a safeguard against the inconveniences and potential data loss caused by unexpected utility power interruptions. UPS systems are designed to step in seamlessly when incoming power experiences disruptions, providing an immediate and uninterrupted supply of electricity.

This is especially critical for businesses and individuals relying on computers or sensitive electronic equipment to carry out essential tasks. For instance, a UPS can ensure that your computer remains operational during a power outage, allowing you to track a package or search for critical information online without missing a beat. In this way, UPS devices not only shield us from the inconvenience of power outages but also help maintain productivity and connectivity when we need it most.

They also include automatic voltage regulation and surge protection, which will ensure surges and spikes in the electricity coming from the electricity 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.

Lithium-ion batteries are increasingly favored for use in UPS devices due to their high energy density and longer lifespan, providing reliable backup energy when needed most.


Unveiling the Power of UPS Devices

In a world where electronic equipment and data centers are the backbone of modern operations, ensuring uninterrupted functionality is crucial.

UPS power supply devices, short for Uninterruptible Power Supply, are crucial for maintaining consistent electricity flow during outages. These devices safeguard sensitive electronics, prevent data loss, and ensure uninterrupted operations in homes and businesses. With various types available, such as standby, line-interactive, and online UPS systems, users can choose the right solution to match their specific power backup needs.

UPS devices stand as a shield against the menace of black outs and unstable electricity. These devices provide a crucial backup electricity source by employing various mechanisms, including double conversion, to convert incoming electricity into a form that can be readily used by sensitive electronic equipment. In addition to their role in power conditioning, UPS devices offer surge protection, shielding against voltage spikes and ensuring that delicate electronics remain unharmed.

Types of UPS Systems

There is no one-size-fits-all solution when it comes to UPS devices, as the requirements of different applications vary widely. Various types of UPS systems cater to this wide range of needs. One common type is the line interactive UPS, which provides an intermediate level of protection, suitable for many home and small office setups. For more critical applications, such as data centers and environments with sensitive electronic equipment, the double conversion UPS system is often the preferred choice. With its ability to maintain a stable and clean electricity source, it ensures uninterrupted operation even when grid fails. Some modern UPS systems also utilize advanced lithium-ion batteries, enhancing energy storage efficiency and lifespan. Ultimately, these UPS devices serve as the backbone of electricity protection, safeguarding businesses and critical operations from the costly disruptions caused by unexpected black outs.


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

How Uninterruptible Power Supply Devices Work

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  UPS Devices?

  1. Keeps IT equipment and computer systems safe and operational when the grid fails
  2. Extends the lifespan of your electronics and appliances by protecting their input electricity from unstable voltage conditions
  3. Allows time for mission-critical system shutdowns during power cuts by supplying short-term energy 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 a electrical system failure occurs
  6. Lowers business interruption costs because work can continue as usual even if the incoming electricity 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 electricity to allow for safe shutdown of equipment, we have an UPS device for you. Discover the basic features of different types of UPS systems 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 electricity 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 blackout, the battery power kicks in and supplies electricity. 

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 electrical 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.
