Three Phase UPS Systems (10-900kVA)

What is a 3 Phase UPS?

Three-Phase UPS systems are designed to provide uninterrupted power to three-phase electrical systems and critical loads. It’s a battery-backed mechanism that keeps critical equipment running during a power outage, while also regulating incoming electricity to protect sensitive appliances.

While single-phase UPS systems can be beneficial, three-phase systems are best for complex loads in buildings with three-phase power supplies.

If you’re new to UPS systems, our Uninterruptible Power Supply guide tells you everything you need to know about how they work.

Where are 3 Phase UPS systems commonly used?

An Uninterruptible Power Supply is beneficial in environments where power disruptions can be financially damaging and impact operations.

For example, if a commercial business loses access to its electricity supply, it won’t be able to serve customers and run IT systems. Industrial environments rely on high-grade equipment, and any outages can lead to operational downtime.

Our three-phase UPS systems are beneficial for a range of environments. We configure each to align with your current power demands and potential future needs.

Common applications include:

• Data Rooms and Server Rooms: Supporting IT infrastructure, including network equipment and servers.
• Commercial Buildings: Offering protection for offices and retail environments that rely on lighting, security systems, lifts, and security.
• Healthcare Providers: Reliable backup electricity for medical equipment, life-saving devices, and anything else that supports patient safety.
• Industrial Environments: Offering a stable power supply for heavy-duty equipment and preventing operational disruptions.
• Telecoms: Maintaining uptime for communications networks, technical installations, and data transmission systems.
• Critical Business Operations: Environments that rely on a continuous electricity supply for operations.

We install each three-phase UPS system on a case-by-case basis. Our specialists will look at your load requirements, site constraints, and other factors to ensure ongoing reliability.

How to Choose the Right 3 Phase UPS?

When choosing a 3-phase UPS system, it’s important to consider the solution that best meets your needs.

For example, it’s not just about choosing the right size; you’ll also need to consider immediate and future load requirements, whether the UPS will be operating in harsh environments, and installation and positioning limitations.

We support businesses across the UK with UPS selection, including full site assessments and ongoing support after installation.

When helping you choose a suitable system, we look at the following factors:

• Load Size: Measured in kVA or kW, the total connected load measures how much equipment you need to run.
• Power Factor: Usable power can differ across UPS systems. However, options like our 10kVA three-phase UPS offer maximum output for your rated capacity.
• Runtime Needs: How much runtime will you need? For example, some UPS systems can provide short-term support, while others offer extended runtime, which is beneficial for critical operations.
• Load Criticality: Which equipment the UPS will be powering, and its importance. For example, healthcare, security, and IT equipment are more important than general tools.
• Battery: Some UPS systems have external battery cabinets, while others include internal batteries, external battery cabinets and extended runtime solutions.
• Accessibility: We’ll also factor in your available space and your site’s layout. This is particularly important in compact spaces, such as plant rooms or highly technical environments.
• Efficiency: Choosing a highly efficient system reduces energy consumption and your carbon footprint. Some three-phase models also have ECO modes to enhance efficiency. –
• Scalability: If you plan to upgrade or buy new equipment in the future, opting for a higher-capacity model can prevent costly upgrades. We often recommend parallel-ready or modular systems in these cases.

All projects are different, but we’ll work closely with you to assess these factors and recommend a suitable system.
