General information and technical advice on power protection and uninterruptible power supply design for server rooms and datacentres.

How to Design a Secure and Resilient Server Room Power Supply

Server Rack Power Supply Design

Power supply design is one of the key decisions that must be taken whenever building a new server room or refurbishing and existing one. There are several elements to consider even for a single stack rack cabinet if you are to ensure that your server installation can run through power outages. When we refer to […]

Selecting an Uninterruptible Power Supply for Your Server Room

Rack Mount Uninterruptible Power Supply

There are two fundamentals to cover when designing server room in terms of critical infrastructure. The first is cooling and the sizing of an air conditioning system to remove heat generated by the servers and provide a suitable working ambient. The second is the choice and sizing of a suitable uninterruptible power supply. UPS Systems […]

How To Improve the Energy Efficiency of Datacentre UPS Systems

Modular UPS Electronics

Energy efficiency is a key metric within server rooms and datacentres. For many colocation and hyperscale datacentres, monitoring how efficiently energy is used is as much about benchmarking as it about reducing electricity bills. Server room and datacentre hardware manufacturers continue to invest in and develop the energyeffiency of their systems. Whether it is a […]

The Key Differences Between UPS, Generators and Energy Storage

Datacentre Backup Power Generators

There is often confusion as to the roles played by UPS systems and generators in critical power protection plans. This is more so now that lithium-ion batteries are also turning uninterruptible power supplies into what are now termed as energy storage systems. What’s the key differences between a UPS and generator? Uninterruptible Power Backup Uninterruptible […]

How Lithium-Ion Batteries Will Change Datacentre UPS Installations

Yuasa Lithium-Ion UPS Batteries For Datacentres

Lithium-ion batteries represent a technology that can disrupt the traditional data centre UPS market place and its reliance on valve regulated lead acid (VRLA) batteries. Other energy storage technologies have tried to disrupt this market place, including super capacitors and DC flywheels. The benefits of lithium-ion (li-ion) batteries mean that this new battery technology is […]

How To Choose Between Single and Three Phase UPS Systems

Sometimes it is easy within a server room or data centre environment to take for granted the relative ease with which we can simply plug IT network servers and peripherals into a PDU outlet or UPS powered socket. These connections form the final element of what we term the ‘critical power’ path. They are the […]

How Generators and UPS Systems Provide Backup Power

Lead Acid UPS Batteries

Generators and uninterruptible power supplies (UPS) are designed to provide back-up power when the mains power supply fails or fluctuates wildly. There is a principle difference between how these two power protection devices achieve this and it lies in the generation and storage of the energy they provide. Prime Power or Standby Power Generators Generators […]

Lithium-Ion UPS Systems For Datacentre Applications

Liithium Ion Datacentre UPS Batteries

The UPS system or uninterruptible power supply that we know today evolved from the oil industry and its need for backup power protection for computer operations in the 1960s. Today’s UPS systems provide a similar solution, but the world of backup power has changed dramatically since that period driven by a host of factors and […]
