FEATURES
Extended Battery Run Time
All models of the XRT series may add multiple optional external XRTBP
battery packs to extend the time that the units can provide power. UPS
de-rating is not required for the additional battery packs. The XRT600
model contains an internal battery, whereas the higher power models
require at least one XRTBP battery pack.
RFI/EMI Suppression
The design features, not only the standard input line filtering, but
contains a specially manufactured transformer
*
that shields the output
from line and inverter spikes resulting from capacitive coupling between
windings. This double protection insures that interference and spikes
cannot get to your equipment, and conversely your equipment cannot
transmit spikes to other equipment on the power line.
No Power Factor De-rating
The XRT series of UPS’s automatically support power factors in the
range of 0.6 to 1.0. This means that no de-rating is required for high
power factors since the unit is capable of supplying full rated power
(instantaneous watts) in either the ON-LINE or On-Battery conditions.
Enhanced Battery Management
To maintain the service life of the battery, the XRT provides various
features. During normal on-line functions the XRT continuously monitors
the battery voltage and keeps the battery at full charge via an intelligent
battery charger built into the unit. The battery’s condition is monitored at
all times, and if a low battery condition is detected, the condition is
reported to the front panel and to the serial communications port. If a low
battery condition is detected, the unit will continue to function on the AC
line. While the unit is on-line, the external battery pack(s) may be
replaced without disruption to the output power. In the XRT1000,
XRT1500 and XRT2000 units, the battery charge condition is reported by
the battery voltage on the LCD display screen, whereas in the XRT600
unit the battery charge condition is reported by LED’s on the front panel.
Remote Communication and Control
Built into the XRT series is a Minuteman standard RS-232
communications port. With the Minuteman Power Management software,
2-way communications can be maintained with a remote computer. All
pertinent data about the UPS can be transmitted to the computer, and
