Safeguarding your critical systems against power interruptions is non-negotiable. A UPS system acts as a vital line of defence, ensuring that your operations remain uninterrupted and your valuable data is protected. But what exactly is a UPS system, and how do you choose the right one for your specific needs? Let’s break it down.
What is an Uninterruptible Power Supply?
A UPS, or Uninterruptible Power Supply, is a device that provides emergency power to your equipment when the main power source fails. Think of it as a safety net for your electronic equipment, providing essential power protection.
How does an Uninterruptible Power Supply work?
Imagine you’re working in your home office, and suddenly, the main power supply goes out. Without a UPS, your computer would shut down immediately, and you might lose any unsaved work. A UPS system steps in during these moments, giving you time to save your work and shut down your equipment properly, or even keeping it running until the power returns.
Here’s how it works:
- Normal operation: When the power is on, the UPS passes electricity from the mains to your devices while simultaneously charging the system’s internal / external batteries.
- Power failure: If the power goes out, the UPS instantly switches to battery power. This happens so quickly (within milliseconds) that most devices see no interruption.
- Battery power: The UPS uses its battery to keep your equipment running for a short period, usually enough time for you to save your work and safely shut down. Depending on the UPS model and the power demands of your devices, this can range from a few minutes to several hours.
- Power restoration: When the mains power returns, the UPS switches back to normal operation, recharging its batteries while supplying power to your devices.
What types of UPS systems are available?
There are three main types of UPS systems, each suited for different needs:
- Standby (Offline) UPS: The most basic type, ideal for home computers and small offices. It provides battery backup and some surge protection but doesn’t regulate power during normal operation.
- Line-interactive UPS: A step up from standby, this type regulates voltage fluctuations in addition to providing battery backup. It’s suitable for small to medium businesses where power inconsistencies are common.
- Double Conversion (Online) UPS: The most advanced level of protection, it provides continuous power from its battery, even when the mains power is on. This ensures the cleanest and most reliable power supply, making it ideal for data centres and critical infrastructure that require continuous operation.
What to consider when choosing a UPS system
Choosing the right UPS for your needs can be straightforward if you know what to look for. Here are the key factors to consider:
- Power requirements: Determine the total power usage of the devices you want to protect with backup power. This will help you choose a UPS with the right capacity. Keep in mind that it’s a good idea to add some buffer to your calculations – aim for a UPS that can handle at least 20-30% more than your total power usage.
- Runtime: How long do you need your devices to stay on during a power outage? UPS systems come with different battery capacities, offering various runtimes. If you just need enough time to save your work and shut down, a few minutes of runtime might be enough. For more critical operations, you’ll need a UPS with a longer runtime.
- Number of outlets: Consider how many devices you need to protect. Make sure the UPS you choose has enough outlets to cover all your essential equipment, like computers, routers, and monitors.
- Form factor: UPS systems come in different sizes and shapes. Some UPS devices are designed to sit on a desk, while others are larger and meant for mounting in a server rack. Choose a form factor that fits your space and installation preferences.
- Features: Modern UPS systems offer various features, such as LCD displays, network management capabilities, and surge protection, to ensure reliable backup power supply. Consider what features are important for your setup.
- Brand and warranty: Like any other electronic device, the brand can matter. Reputable brands often offer better build quality, customer support, and longer warranties. Make sure you choose a UPS with a warranty that gives you peace of mind. We offer a variety of UPS products from manufacturers such as Riello UPS, Ablerex, Vertiv, Eaton and APC by Schneider Electric.
A UPS system is a crucial investment for anyone relying on electronic devices. Understanding how UPS systems work and what to consider will help you make an informed choice to protect your equipment and ensure smooth operations during power outages.
