UBR (1-3kVA)

UBR (1-3kVA)

True double-conversion

Categories: , ,

UBR is small capacity UPS of KSTAR, the output factor is 0.9, and the power range is from 1kVA to 3kVA. Deployment is very flexible, tower and rack-mounted can be configured according to customer’s requirement. When UPS is on battery mode, it can shut down unnecessary load and extend the backup time of the critical load.
