Three Phase UPS Systems

Three phase uninterruptible power supplies for server rooms and datacentre applications from 10kVA upwards. The UPS systems in this range are three phase input UPS and may have a single phase output or a three phase output. Some models can be parallel to provide capacity or resilient (N+X) configurations. Batteries may be internal or supplied in external battery cabinets or on open or cladded racks.

Uninterruptible Power Supply Projects

Server Room Environments maintains stock within its UK-supply chain to guarantee quick delivery for individual unit purchase and ‘turn-key’ projects. We also provide short, medium and long-term UPS hire and rental options for some model sizes. The UPS systems are designed for installation in a server room, UPS room or other suitable facility, as well as containerised power solutions.

Three Phase UPS Lithium-ion Battery Options

The standard battery used within these three phase uninterruptible power supplies is a sealed valve regulated lead acid (VRLA) maintenance free battery. The battery will have either a 5 year or 10 year design life option.

Server Room Environments can also supply Lithium-ion batteries and battery management systems for use with some UPS systems. Lithium-ion based UPS systems are more suited to more rapid charge/recharge cycles, use as virtual power plants (VPP) and within demand side response programs run by the National Grid.
