What Is a UPS (Uninterruptible Power Supply)?

A UPS (Uninterruptible Power Supply) is a device that provides instant battery backup and voltage regulation during power outages or fluctuations. It ensures that connected devices such as computers, servers, routers, and security systems continue running safely without interruption. UPS systems are essential for protecting sensitive electronics from:

• Power outages
• Voltage spikes and surges
• Data loss and system crashes

UPS Types and Their Differences

UPS systems are available in different designs to suit different power protection requirements.

Offline or Standby UPS

Normally switches to battery power when the incoming mains supply falls outside the unit's operating range, making it suitable for basic backup applications.

Line-Interactive UPS

Adds voltage regulation to help manage certain fluctuations in the incoming power supply while also providing battery backup.

Online UPS

Uses a double-conversion design, where incoming AC power is converted and then supplied to connected equipment through the UPS, making it suitable for applications that require a more controlled power supply.

UPS Systems by Capacity

UPS systems are available in different VA and kVA capacities for different equipment loads and applications. The appropriate UPS capacity depends on the connected load, required runtime, UPS type and installation requirements. Common UPS capacities

• 600VA UPS
• 650VA UPS
• 850VA UPS
• 1KVA UPS
• 1.5KVA UPS
• 2KVA UPS
• 3KVA UPS
• 5KVA UPS
• 6KVA UPS
• 10KVA UPS
• 20KVA UPS
• 30KVA UPS
• 40KVA UPS

UPS vs Inverter: What's the Difference?

A UPS and an inverter can both provide backup power, but they are designed for different applications. A UPS is generally designed to provide backup power with a rapid transition and power protection features for connected equipment. Inverters are commonly used as part of broader backup-power systems and may support larger batteries and longer backup periods depending on the system design. For computers, networking equipment, servers and other sensitive electronics, the appropriate solution depends on the equipment's power requirements and the characteristics of the backup system.

Choose the Right UPS for Your Setup

A single-phase UPS is commonly used for individual equipment, offices, and smaller installations, while a three-phase UPS is designed for electrical systems and applications requiring three-phase power. UPS units are also available in rack-mount and tower designs to suit different installation environments. Before buying a UPS, consider the following:

1. Determine your equipment load

Add up the power requirements of the equipment you want the UPS to support. Check both the VA and watt requirements where available.

2. Choose the UPS capacity

Select a UPS with sufficient capacity for the connected equipment. Allowing some additional capacity can also provide room for future equipment, where appropriate.

3. Consider the required backup time

UPS runtime depends on the connected load, battery capacity, UPS efficiency and operating conditions. Check the manufacturer's runtime information for the specific model.

4. Choose the appropriate UPS type

Consider whether an offline/standby, line-interactive or online UPS is appropriate for your equipment and power environment.

5. Check the electrical configuration

Confirm whether your installation requires single-phase or three-phase power.

6. Consider the installation format

Choose between tower and rack-mount UPS designs according to your available installation space and equipment configuration.

7. Check battery requirements

For replacement batteries, verify voltage, Ah rating, dimensions, terminal type and compatibility with the UPS model.

UPS Replacement Batteries

UPS batteries are replaceable components that provide stored energy when mains power is unavailable. When replacing a UPS battery, check the voltage, Ah capacity, physical dimensions, terminal configuration and UPS model before ordering. We supply UPS Systems replacement batteries in different capacities and configurations for supported UPS systems.

Portable Power Stations and Accessories

A power backup station is a rechargeable, battery-powered unit that stores electricity and provides power to devices when mains power is unavailable. It can be used at home, outdoors, during emergencies, or in off-grid situations, with different models supporting devices such as phones, TVs, laptops and other equipment. Depending on the model, a power station may include AC outlets, USB ports and DC outputs for connecting different devices. Power station accessories can further extend the convenience and functionality of your unit. These may include compatible solar panels, charging cables, AC adapters, car charging cables, expansion batteries, connectors and carrying cases for charging, connecting, expanding or transporting the power station.
