KSTAR Online Transformerless Commercial UPS - UB (1-3kVA)

$0.00

1-3kVA
 
UB series power supply adopts online double conversion design and digital control technology and it features high input and output power factor(0.9). With ECO mode for energy-saving, intelligent battery management and excellent network management, it is a cost-effetive power solution for your critical devices. When UPS is on battery mode, it can shut down unnecessary load and extend the backup time of the critical load.


 True double-conversion

● Digital control guarantees high reliability

● ECO mode operation for energy saving

● Output receptacle control for non-critical load shedding capability

● 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
