Uninterruptible Power Supply

An uninterruptible power supply (UPS) is a backup power device that keeps equipment running during outages and shields it from surges. It bridges short blackouts, giving you time to save work, stay connected and shut down devices safely. Explore more of our electrical products to keep your setup running reliably.

ower cuts, surges and brownouts can do more than interrupt your day. They may cause data loss, damage equipment and lead to costly downtime. A UPS gives homes and businesses backup power to reduce those risks. For devices like PCs and routers, it provides enough time to stay online and finish important tasks. For servers, it ensures cleaner shutdowns and prevents corruption. Sensitive electronics also benefit from stable, filtered power, which extends their lifespan.

UPS systems fall into three main types, each meeting different needs. Your decision comes down to power stability, cost and how vital the equipment is.

A standby UPS is an entry-level option that offers a quick switchover during a blackout. It suits basic devices such as home PCs and modems. Standby models are a cost-effective way to handle short outages and give peace of mind at home.

Line interactive UPS units regulate voltage, protecting against brownouts and minor fluctuations. They are ideal for small servers, NAS devices and office workstations. With built-in stability features, they are a strong choice for most small office setups.

For critical equipment, an online double conversion UPS delivers the cleanest power with zero transfer time. It is designed for servers, network racks, medical systems and other high-value gear. By constantly converting and conditioning power, it removes spikes, noise and interruptions.

Selecting the right UPS means matching its VA and watt rating to your devices. Decide how long you need it to run, usually measured in minutes, and allow some headroom for future growth. Check the power factor of each model and consider expansion batteries if a longer runtime is required.

Uninterrupted power supply for the home keeps your PC and router online just long enough to save files and avoid call or meeting dropouts. Standby or line interactive models are a good starting point.

Keeping modems, routers and switches running is critical for communication and cloud services. Compact UPS units with multiple battery-backed outlets work best here.

Servers need stable power and enough time for graceful shutdowns. Line interactive or online units sized to rack loads provide monitoring features and support longer maintenance windows.

Security and sales systems must stay operational during local power cuts. Choose UPS models with sine wave output and enough runtime to keep recorders and tills live.

Match the UPS type to how critical your equipment is. See the ‘Types of UPS’ section above for guidance.

Yes. Uninterruptible power supplies are useful for home offices and study spaces. Size it to cover your PC and router.

The length of time UPS will run your equipment depends on the total load and the battery capacity of the unit. Check the runtime tables on each product page.

Yes, you can replace UPS batteries on supported models. Use the correct battery kit and recycle the old one responsibly.
