What is a single-phase UPS?

A single-phase UPS is an uninterruptible power supply that provides battery power during voltage fluctuations and outages.

These systems are compatible with single-phase equipment and appliances and can condition your mains supply to reduce fluctuations.

The majority of small buildings in the UK use a 230V single-phase electricity supply, so these UPS systems are the ideal choice.

How to Choose the Right Single-Phase UPS?

Finding the right single-phase supply is vital for powering critical loads and ensuring long-term business support. If you’re unsure of which solution best fits your needs, our experts are here to help.

When determining the right single-phase system, we look at the following factors:

  • Load Size: How much electrical power do you need to power equipment. We measure the complete connected load in watts/kVA to determine system capacity.
  • Runtime Needs: How long the equipment needs to remain operational during a power cut.
  • Applications: Will UPS provide backup power for the critical or non-critical equipment?
  • Input/Output Requirements: Assessing the suitability of single-phase input and output.
  • Installation Format: Deciding between Tower UPS and Rack Mount UPS systems, which depends on the layout and space.
  • Scalability and Redundancy: Choosing a larger system can support parallel operations.
  • Battery Configuration: Internal batteries are more convenient, but external cabinets can be beneficial for extended runtime.
  • Efficiency: Some systems have ECO modes that can decrease future running costs.

While single-phase systems are suitable for the majority of small businesses, Three-Phase UPS systems can support more complex installations or larger setups.

FAQ

What is the difference between a single-phase and a three-phase UPS?

Single-phase UPS systems are ideal for smaller installations such as offices, IT setups, and retail spaces. A three-phase UPS system is best for high-capacity equipment and large industrial applications. If you’re unsure of which system you need, our specialists can offer advice.

What size single-phase UPS do I need?

It depends on your runtime requirements, total load, and future capacity requirements. Once we perform a load assessment and site survey, we’ll be able to recommend a suitable size.

Is a rack mount or tower UPS better?

There’s no “best” solution, because it depends on your setup. For example, rack-mounted systems are best for server environments with existing cabinets, while tower UPS systems are better for sites without an existing rack structure or standalone installations.

How long will a UPS run during a power cut?

The runtime of your UPS depends on the load size and capacity. Some systems are best for short-term support, while others offer extended runtime – especially when you have extra battery cabinets.

Can a UPS be used with a generator?

Yes, many businesses install UPS systems alongside generators. These setups offer seamless power during transitional periods and can stabilise your supply.

Do you offer UPS installation and servicing across the UK?

Absolutely, our services include nationwide support. You can benefit from expert system design, installation, commissioning, and ongoing maintenance.
