Isolation in a UPS system
Three distinct types of isolation may be used within a UPS system, although how – or even if – they’re implemented depends on the UPS type and the application. In...
A compact, reliable battery solution for mission-critical applications
Today, data centre operators have two dominant battery chemistry choices for their UPS backup systems; Valve Regulated Lead Acid (VRLA) or lithium-ion (Li-ion). Of the two, the longer-established VRLA persists...
Reliability is great, but availability is better
If asked to name our UPS’s most vital attribute, we may be tempted to say ‘reliability’. However, while reliability is indeed essential, it’s not the ultimate goal. What really counts...
Some practical load aspects to consider when specifying your UPS
When specifying a UPS, you would no doubt choose a capacity that would be adequate for the data centre or IT room that it’s intended to support, with provision for…

Sharing the load: How UPS systems use multiple technologies to deliver best in class efficiency
Data centre operators, like any other business, are under continuous pressure to improve their energy efficiency. This is partly due to rising fuel costs, but also because shareholders, business partners…
Decentralised parallel architecture – what it is, and why it’s essential for ‘True Modularity’
Transformerless UPS technology, once established, rapidly became dominant because it enabled much smaller, lighter solutions. These allowed systems to be built from several relatively small modules rather than a single…
Mitigating a UPS system’s environmental impact and susceptibility
A data centre UPS is a significant, high-performance unit that can both impact and be impacted by its environment in various ways. This post looks at these environmental factors and…
