MEMOPOWER II
1-3kVA
MEMOPOWER II 1-3kVA is small power UPS of KSTAR, both input and output are single phase, the output factor is 0.8.When UPS is on battery mode, it can shut down unnecessary load and extend the backup time of the critical load
General Features
● High power density
● Output power factor up to 0.9
● Three stage charging mode extends battery life，optimizes recharging time
● Selectable high efficiency mode of operation
● Cold start
● Self-testing when UPS startup
● Standard communication options: RS232 communication port, USB communication port, and relay output contacts or SNMP card
● Extended runtime with up to four extended battery modules (EBPs) per UPS
● Emergency shutdown control through the remote emergency power-off (EPO) port
● Versatile LCD human-computer interface
