Battery:
Battery type/voltage: maintenance-free sealed, valve-regulated, Lead-acid: 6V 9Ahx3 (18V DC), 6V 9Ahx4 (24V DC)
Backup time: 12 minutes at 1/2 load, 4 minutes at full-load typically
Charging time/current: <3 hours to 90% at normal status, 2.5A (average with 2 charging modes)
Protection: over current protection and over charging voltage protection (SCR control), thermal protection (CPU control), when temperature inside USP is over 45°C, charger will stop charging for 2.5 minutes followed by an 1.5 minutes charging the cycle will be repeated until the temperature is lower than 44°C
Monitoring: smart monitoring and warning for failed battery or open-circuit battery
Auto-detection each time when power on or every 6 days
Communications and management:
Standard interface port: UPSilon2000 compatible RS232, USB, SNMP (external type)
Optional interface part: DB9
Control panel: LCD or LED
Audible alarm: alarm on battery: low battery and battery over voltage, alarm on abnormal operation: over load, short-circuit and over heat
EBT system: supports for LCD display (estimation of backup time)
Green mode function: 1 to 14% of full load (adjustable with the remote set-up software), default=off
