• Wide AC input voltage range (176/ 304Vac ~ 276/ 478Vac (full load); 132/ 228Vac ~ 276/
478Vac (70% load)) reduces frequent transfer from normal mode to Battery mode to
save battery consumption and prolong battery life.
• Battery start-up function even when there is no AC input.
• AC start-up function even when the UPS is not connected to the batteries.
WARNING:
Please note that when the UPS is not connected to the batteries, it will not
protect your equipment if the utility power is lost.
• Connects at maximum four external battery cabinets (optional) to extend the backup
time.
• Setting options of battery test (schedulable) and battery replacement alarm.
• Battery temperature monitoring and compensation.
• Optional battery management system (BMS) allows measurement of every battery’s
voltage.
• Smart battery charger design allows auto-charging or manual charging to shorten the
charging time.
• Provides diversified communication interfaces and a SMART slot. Please refer to
4. Communication Interfaces
.
• Built-in memories record at maximum 10,000 event logs.
• Fan speed auto adjustment prolongs fan life and reduces noise when the critical loads
decrease. Moreover, fan failure detection circuit is established.
• State-of-the-art microprocessor technology performs self-detection and monitors fan
speed in real time, which provides complete and detailed operating status of the UPS.
