Flexible UPS systems share a single battery size

An innovative new series of online, uninterruptible power supplies employs a single, standard battery across the range and can be used in stand-alone, rack-mounted, or stacking formats.

The new 4, 5 and 6kVA versions extend the Xi UPS family of modular power supplies that start at 1kVA ratings.

All models are just 510mm deep, enabling them to fit onto a standard telecomms rack; the 6kVA version is believed to be the only UPS on the market that achieves this at its power rating.

The Xi features dual inputs to ensure supply integrity, a rotating backlit LCD, and load segment control to permit shut down of noncritical loads while increasing autonomy on critical loads.

No system module weighs more than 40kg, making the UPS easy to install and relocate; similar units from other companies often weigh up to 100kg.

Xi power supplies are typically 90% efficient.

The adoption of a single battery for all models ensures availability of supply and simple, safe user configuration on site, whilst reducing inventory and therefore overall system cost.

The flexible, modular design offers inventory savings too, and users can change from stand-alone to rack-mounting or stacking configurations as their needs change.

Xi series UPS accept dual mains inputs so that in the event of failure of one mains supply the unit will take power from an auxiliary supply to ensure the battery backup capability is maintained.

The rotating dual-line LCD allows users to read up to eight key functional parameters, such as input voltage and output load data, with ease, whatever the physical orientation.

The input voltage range is from 176 to 276V AC (50/60Hz) at full load 230V AC nominal, which widens to 120 to 276V AC (50/60Hz) at 25% load.

The output voltage is selectable to 200, 220, 230 or 240V AC with output regulation of +/-2% of nominal voltage and total harmonic distortion at less than 3%.

Electronic load sensing protects the output and fault conditions are indicated both on the LCD panel and by an audible alarm.

Each Xi battery module houses two VLRA-type battery packs with a 5-year design life.

They take less than 4h to recharge to 90% capacity and are hot-swappable.

Monitoring and control is provided via an RS232 interface and the software supplied with the UPS supports all versions of Windows, plus Novell and Linux.

Xi uninterruptible power supplies are IP20 rated and designed to operate in ambient temperatures from 0 to +40C.

They meet applicable safety and EMI requirements and are designed and are built in XP's ISO9001 approved facilities.
