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...
Centralised and Decentralised Static Switches Ideally, UPS power systems will fulfil the promise of its name, delivering clean, processed power at all times. Real data centres, however, ensure that their...
Although modern transformerless UPSs offer a flat efficiency/load curve for loads of about 25% or more, efficiency will drop significantly at lower levels. However, a solution exists, in the form...
Some UPSs need just simple communications capability to warn their critical load of an impending failure. Larger, more complex or widely distributed systems benefit in many ways from more sophisticated,...
Data centres need protection from power abberrations during normal mains operations as well as complete and extended power blackouts. Although compromises can sometimes be made, the best and most comprehensive...
Hook, Hampshire, December 14, 2017: This December marks the 20th anniversary of Kohler Uninterruptible Power Limited (KUP), a Kohler company – one of the UK’s largest UPS sales and service companies....
At the most general level, all modern static UPSs comprise a rectifier/charger, battery, inverter and static switch. These components allow the UPS to charge the battery when the utility supply...
Modern, static UPS systems are classified as either on-line or off-line, with some off-line variants known as line-interactive types. Nearly all data centres and other application with critical loads will...
Today, a typical organisation’s performance is only as good as its ICT resource - which depends in turn on the quality and continuity of its power supply. Accordingly, data facilities...
Modular UPS technology, as implemented in systems such as KUP’s PowerWAVE 9500DPA, is now being exploited in a smart solution that maintains UPS efficiency even when the UPS load is...
In their in-depth ‘Football Stadiums: Technical recommendations and requirements’[i] guide, FIFA writes: “The delaying or cancellation of an event due to the loss of electrical mains is unacceptable. A careful...
While UPSs provide essential battery backup in the event of a mains failure, they also protect their critical load from mains disturbances during normal operation. Alan Luscombe, director at Kohler...
