introduction
In critical situations, count on MGE UPS
SYSTEMS Pulsar EX20 Rack and
EX30 Rack uninterruptible power supplies
(UPS). Their protection keeps your data
intact and accessible.
Pulsar EX20 Rack and EX30 Rack UPSs
ensure top quality power around the clock,
and continue operations during power
failures. An intelligent microprocessor
detects any operating anomalies of the UPS
and triggers an alarm if corrective action is
necessary.
In addition to the high-technology aspect of
these UPSs, you can count on backup from
our staff, a team of specialists, around the
corner from you, throughout the world. It's
no accident that MGE UPS SYSTEMS is the
world leader in UPS protection. The UPS
provides power factor correction to reduce
harmonic distortion and current created by
non-linear critical loads from polluting the
incoming AC line.
UPS includes:
batteries,
power factor correction / battery charger,
DC to DC converter,
DC to AC inverter,
bypass switch,
input/output filters.
The MGE Pulsar UPS is capable of
providing the following modes of operation:
ON LINE MODE which is the primary
mode of operation in which the critical load
is continuously supplied by the inverter and
protected from all forms of power line

uses of Pulsar EX20 Rack and
EX30 Rack :
Network servers and interconnection
devices are very sensitive to electrical
disturbances of all types, including outages,
voltage sags, brownouts, spikes, etc. The
origins of the disturbances also vary, ranging
Pulsar EX Rack : 86-153500-00
from atmospheric phenomena, to nearby
devices generating interference such as
elevators, photocopy machines and machine
tools, not to mention human errors, like the
accidental pulling out of power cords or
critical
system
tripping of circuit breakers. The
consequences of these disturbances on
computer systems range from data losses to
hardware damage (power supplies, hard
disks).
Pulsar EX20 Rack and EX30 Rack are
specially designed to protect network
servers and all other interconnection devices
that are sensitive to electrical disturbances.
Pulsar EX20 Rack and EX30 Rack add fault-
tolerance to the utility supplying your
sensitive equipment.
Pulsar EX20 Rack and EX30 Rack are
designed as compact units and feature very
quiet operation.
Pulsar EX20 Rack and EX30 Rack provide a
critical stable supply of clean power, long back-up
system
time during a utility outage (see table) and
vast information and control possibilities
according to the configuration selected.
Pulsar EX20 Rack and EX30 Rack On-Line
technology provides maximum protection
and availability of workstations, servers, and
network communication devices.
Pulsar EX20 Rack and EX30 Rack offer
many functions and characteristics designed
to simplify power management:
automatic battery test carried out
periodically. In the event of a fault, a LED
provides advance warning for battery
replacement;
front panel LEDs signal all types of faults
and alarms;
