3kVA UPS systems available from Server Room Environments include line interactive and on-line uninterruptible power supply systems. 3kVA UPS will be rated at 3000VA and have different output Watts rating dependent upon the power factor used by the UPS manufacturer. Please check the individual products for their kW rating. The output connections can be plug and play or hardwired dependent on the model which can be available in free standing tower or 19inch rack mount formats with options for extended battery runtimes.
3kVA UPS typically provide either a hardware back plate and terminals or a selection of output sockets including IEC and for the UK market a 3-square pin. The mains input power supply may be hardwired to the terminals from a fused spur or plug-in (16A blue Commando industrial).
UPS runtimes are dependent upon the size of the battery set (Ah) and the load applied to the UPS (kVA or kW). If you select a 3kVA with a 5minute battery runtime and run this at half-load i.e. 1.5kVA, the UPS will provide double the amount of runtime. For longer runtimes than is available from the internal battery, battery extension packs can be connected to the uninterruptible power supply, where the UPS has a connection for these.
3kVA uninterruptible power supplies are designed to power loads up to 3kVA but the kilo-Watt loading will depend on the UPS output power factor.
Typical loads for a 3kVA UPS include file servers, storage devices IT networks and VoIP telecoms systems. Industrial loads can include process control applications and sensitive electronic devices that require a conditioned mains power supply and battery backup.
This is not an exhaustive list but provides some general check points when preparing to install a 3kVA uninterruptible power supply.
Server Room Environments provides a complete project managed service including UPS site surveys, turn-key systems including PDUs (power distribution), UPS maintenance bypasses, network interfaces for remote monitoring, standby power generators for extended backup times, UPS installation and maintenance contracts.
