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 or a selection of output sockets including IEC and for the UK market a 3-square pin.
The UPS will have an internal battery. 3kVA UPS may have a rear panel connector for an external battery pack. The amount of battery runtime available is dependent upon the load placed onto the UPS and the age, battery charge % and ambient environment.
