Intelligent design
Integrated with a microprocessor, the UPS is able to perform intelligent functions. The
UPS triggers over-voltage protection function and transfers to "On- Battery mode" even
when utility voltage exceeds 300V for 200V-series. In addition, the UPS can accept large
voltage variation of 65V to 138V for 100V-series or 130V to 275V for 200V-series.
Wide input voltage range means less battery power usage frequency and longer battery
life-span. Besides, programmable outlet design, suitable for power management, is also
included in this unit.
Considerate design
Battery start function allows startup of the UPS even when there is no AC line available.
In addition, the UPS which was shut down by remote control during power line blackout
will restart automatically when AC power recovers. Using our automatic frequency
sensing function to match input and output frequency, users don't need to set either 50Hz
or 60Hz. Other features, such as UPS self-diagnosis and flexible external battery pack,
are also included.
Green function design
The UPS comes with an intelligent fan design, which can have variable fan speed
depending on load status, thereby saving the use of power and reducing audible noise.
Besides, the operation in sleeping mode is designed to just keep charging which saves the
energy a lot.
User friendly interface
The UPS provides a variety of functions which meet users' needs. Users can instantly
understand the status of the UPS via the informative LED display. Audible alarms, bar
meters and status indicators, such as battery replace indication, UPS fault, line condition,
overload etc. are simple and easy for user to understand. Moreover, users can simply reset
the circuit breaker instead of having to replace a fuse in the event of output overload.
Safety approvals
The UPS has passed various safety regulations. UL/cUL, TUV/EMC, TUV/GS, CE mark
and other safety approvals, proves that the UPS is a safe reliable solution to your power
problems.
Network Management
Build-in communication interface port supporting RS232 and Dry contact protocols
enhances the reliability and manageability of the UPS over all major operating systems,
including Windows 95/98, Windows NT, Netware, Unix, and others. Besides, the UPS
also supports the Simple Network Management Protocol and Hyper Text Transfer
Protocol via plugging a SNMP/HTTP adapter into the build-in SNMP slot.
