What is an Uninterruptible Power Supply (UPS)?

An uninterruptible power supply is a device that provides temporary backup power when the mains supply fails. It includes an internal battery that keeps essential equipment running long enough to shut down safely or switch to another power source. 

Alongside battery backup, many uninterruptible power supplies also help protect against voltage spikes, sags, and surges. This can be especially useful when used with surge protectors or PDUs in environments that demand stable performance.

Types of UPS Systems: Choosing the Right Technology

Offline / Standby UPS

A standby model is typically the simplest option. It is ideal for home offices, basic PCs, small networking devices, and any situation where a short backup time is enough to protect your data. It activates when the incoming power drops unexpectedly.

Line-Interactive UPS

A line-interactive option is a popular choice for servers, telecom gear, and general business equipment. It offers voltage regulation in addition to battery backup, which gives you more protection against common power problems across NZ.

Online / Double-Conversion UPS

This is the most advanced type and is common in hospitals, industrial automation, and data centres. An online unit provides continuous clean power by converting incoming electricity twice. It suits any environment where even brief power interruptions are unacceptable.

How to Choose the Right UPS System for Your Needs

When comparing UPS systems, it helps to focus on a few key factors:

• Power requirements: Add up the total wattage of all equipment you want to protect. Choose a UPS that can comfortably support that load.

• Required runtime: Think about how long your devices need to keep running during an outage. Some setups only need enough time to shut down safely, while others require longer backup.

• Type of application: Match the UPS technology to the sensitivity of your equipment.
  • Standby units work well for basic home office gear.
  • Line-interactive models suit small businesses, servers, and networking hardware.
  • Online double-conversion UPS systems are ideal for critical medical, IT, or industrial equipment.

• Form factor: Decide whether you want a tower unit for desks and floors or a rack-mount option for server cabinets.

• Future expansion: Consider whether you might add more devices later so you can choose a model with enough capacity to grow.
