2.2. The Advanced Technical Characteristics

 Powerful CPU integrates all power stages, control, and communication functions

necessary for maximized UPS protection and functionality, including power

management status monitoring, configuration setting, operation scheduling, remote

control, and self-diagnosis.

 Slick multi-protocol CPU communication design allows full function remote control

from any computer environment via standard RS232 interface using any of MegaTec

Protocol, and basic dry-contact signal pattern (optional relay contact board required).

 Fully isolated Online architecture completely segregates input, control, and output

circuits, providing the ultimate level of power protection for connected equipment.

 Industry leading inverter protection technology incorporated 2-stage output current

sensor, smart overload output current control, improved crest factor, and feedback

failure proof circuit, elevating the availability of power service.

 Absolutely zero DC component, resulted from superb inverter-output isolation,

guarantees an exclusive protection against DC damage for inductive load, such as

motor based devices, entirely eliminating application limitation.

 State-of-the-Art IGBT technology and industrial grade quality ensures highest

efficiency and reliability under worst operation condition.

 Advanced Input PFC control guarantees the PF performance and maximum energy

efficiency.

 Independent over-voltage trip-over circuit retains full over-voltage protection even

during UPS failures and bypass mode.

 Automatic Frequency Sensor reduces headache in frequency shift.

 Revolutionary battery management circuit analyzes battery discharging duration,

discharging current, and battery temperature in order to determine ultimate setting of

charging voltage, charging mode, and discharge cut-off level, thereby maximizing the

efficiency and life of batteries.

 DC-start function makes sure of the start-up of UPS during power outages.

 Superior charger protection design fully protects charging mechanism from terminal or

battery short circuit, without ever interfering with the UPS operation.

 Full size LCD panel displays complete system, load/battery status, and problem

diagnosis report, completely eliminating user gap.

 SNMP adapter slot represents the advanced upgrade solution to achieve direct power

management via internet worldwide

 EPO and Maintenance Bypass Switch ensure a safe operating environment.
