Power's Flexible Series wide temperature battery UPS is an excellent
choice for those applications that require battery backup with good
surge protection, a wide temperature battery for usage in more extreme
environments, and the flexibility of being able to add additional
battery cabinets for extended run-time.
Typical
Applications
UPs-400Wtb is the ideal UPS for
computer or telecommunications equipment in extreme wide temperature
(-20o to +60oC) environments where ac power
delivery is unreliable and long battery backup times may be necessary.
The UPs-400Wtb is suitable
where power outages are a regular occurrence, or in areas where
utilities need to conduct rolling blackouts.
Key Benefits of
the UPs-400Wtb
The
UPs-400Wtb protects connected equipment from: power supply failure,
erroring, system lockups and re-boots. It contributes to enhanced
systems operation, greater reliability, improved repeatability, and
extended operating life.
Typical back-up time fully loaded is 8 minutes,
but 20 minutes can be obtained when the unit is loaded to 50% of its
capacity. Thus, an application requiring 200VA can be provided with 20
minutes of hold-up. The
capability of adding extra EXt-400Wtb external battery packs also makes
this a very cost-effective choice for enabling nearly unlimited holdup
times. Custom Settings: DIP switches in the rear panel
allow the user to set brownout sensitivity, inverter operating
frequency, or alarm mode, for complete flexibility and control of the
UPS.
How the
UPs-400Wtb
Works
The UPs-400WTB continually provides
surge protection with a capacitive element, and coordinated MOV surge
protection. Upon loss of power, the audible alarm beeps about once a
second, as the battery inverter kicks in within 8ms, which means
equipment will continue to operate without interruption.
When the battery level drops until only a
few minutes of holdup time remain, the alarm will beep, and the LED will
flash more rapidly, alerting of impending shutdown. A DB-9 female
connector provides communications capability with monitoring software
which can safely save open files and automatically shutdown your
systems.
