1. Introduction
Thank you for your purchase of the Esprit rack
"UPS" from MGE. The Esprit "UPS" will provide
many years of, trouble-free power protection for
critical high availability servers and other devices.
Please read this manual fully, to familiarize yourself
with the safety instructions and Esprit features.

other fine products.
Why the Need for Uninterruptible
Power?
Servers and other electronic devices do not store
sufficient energy to overcome the power outages
and short interruptions that occur on a daily basis.
Any interruption of the utility power may stop the
operation of a computer and cause loss of data,
potential hardware damage, and inconvenience.
A "UPS" is an uninterruptible power supply. The
UPS has an internal battery to provide power
back-up if the utility power is lost or a short outage
occurs. In addition, the Esprit UPS provides surge
protection from indirect lightning strikes, power
surges and short high voltage transients (spikes)
created by machinery or other common equip-
ment.
Theory of Operation
Esprit normally operates in the bypass mode.
Surge suppression and filtering are also provided
in this mode.
The UPS instantly transfers the load to the battery
when a power failure occurs. If the power returns
before the battery is exhausted, the operation
returns to normal and the battery is recharged.
The Esprit UPS is comprised of three major
systems: the inverter, the battery/battery charger
and the bypass.
All logic and supervision in the UPS is provided by
a state-of-the-art micro-controller.
Inverter
The inverter is the heart of the UPS and inverts
direct current (DC) from the battery into
alternating current (AC) at 120 volts. The DC voltage
from the batteries is converted into a pseudo-sine
wave by a pulse width modulated (PWM) inverter.
Other products
This unique MGE technique, eliminates all bulky
60 HZ components, reduces heat, and greatly
and
isolation
enhances reliability.
Battery
The battery provides the energy source for back-up
when a power failure occurs. The battery is a
recombinant, sealed, lead acid-type battery which
provides the high current required for UPS use
and long life. It requires no addition of water during
its life.
Battery Charger
The battery charger maintains the battery. The
battery charger converts 120 volt AC utility power
to filtered and regulated DC current specific for
battery charging.
Bypass
The bypass is the electro-mechanical hardware
providing a transfer to or from the inverter. This is
done rapidly and synchronized to the utility power
sine wave in order to provide continuity to the critical
device and not cause a re-boot.
