OVERVIEW
The CST150XLU provides complete power
protection from utility power that is not always
consistent. The CST150XLU features 1500
Joules of surge protection. The unit provides
long lasting battery backup during power
outages with maintenance free batteries. The
CST150XLU ensures consistent power to your
computer system and includes software that
will automatically save your open files and
shutdown your computer system during a
utility power loss.
AUTOMATIC VOLTAGE REGULATOR
The CST150XLU stabilizes inconsistent utility
power voltage to nominal
levels that are safe for
equipment. Inconsistent
incoming utility power
may be damaging to
important data files
and hardware, but with
Automatic Voltage
Regulation (AVR),
damaging voltage levels are corrected to safe
levels. AVR automatically increases low utility
power or decreases high utility power to a
consistent and safe 110/120 volts.
DETERMINE THE POWER REQUIREMENTS
OF YOUR EQUIPMENT
1. Ensure that the equipment plugged into
the UPS does not exceed the UPS unit’s
rated capacity. If the rated capacities of the
unit are exceeded, an overload condition
may occur and cause the UPS unit to shut
down or the circuit breaker to trip.
2. There are many factors that can aect
the amount of power that your electronic
equipment will require. For optimal system
performance keep the load below 80% of
the unit’s rated capacity.
