UBR
1-3kVA
UBR is small capacity UPS of KSTAR, the output factor is 0.9, and 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.
General Features
● True double-conversion
● Rack-mounted and floor-standing tower can be convertible
● Patented Mimic LCD of which content can be rotated according to the type of deployment
● Digital control guarantees high reliability
● Output receptacle control for non-critical load shedding capability
● ECO mode operation for energy saving
● Emergency power off function(EPO)
● Generator compatible
● Communications:RS-232,USB,SNMP card(Optional), Relay card (Optional)
● Bypass can be used when UPS is off(Setted in LCD)
● Cold start
