Why the Need for Uninterruptible Power?
PCs and other electronic devices, due to
their design, are subject to the effects of
power outages or short interruptions. They
do not store sufficient energy to overcome
outages or short interruptions and these
events occur on a daily basis. Any
interruption of the utility power will 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 when the utility power is lost
or a short outage occurs. In addition, the
Ellipse UPS provides surge protection from
indirect lightning strikes, power surges and
short high voltage transients (spikes)
created by machinery or common office
equipment.
A fax/modem (with cable) or
network suppressor is provided with every
MGE Ellipse UPS to also protect the
incoming data line to the PC.
Theory of Operation
Ellipse is an off-line or stand-by UPS which
normally operates in the bypass mode.

86-153506-00 Rev. A01
Surge suppression and filtering are also
provided in this mode.
The UPS transfers the load quickly 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 Ellipse UPS is comprised of three major
systems: the inverter, the battery charger/
battery and the bypass.
All logic and supervision in the UPS are
provided
by
a
state-of-the-art
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.
is:
The DC voltage from the batteries is
switched on and off at a high frequency and
transformed to a higher voltage (DC to DC
conversion).
After conversion, the high
voltage is converted into a pseudo-sine wave
by a pulse width modulated (PWM) inverter
to 120 volts AC RMS. This unique MGE
technique, eliminates all bulky 60 HZ
components and reduces size, heat, and
greatly enhances reliability.
Battery Charger/Battery
The battery charger maintains the battery
and the battery provides the source of back-
up energy when a power failure occurs. The
battery charger converts 120 volt AC utility
power to filtered and regulated DC specific
for battery charging.
The battery is a
recombinant, sealed, lead acid-type which
provides the high current required for UPS
use and long life. It requires no additions of
water during its life.
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 PC and
not cause a re-boot.
