The following is a description of the Comet UPS major
internal components. Refer to the single-line diagram
provided in Figures 1-2, 1-3 and the internal component
views provided in Figures 1-4, 1-5, 1-6, 1-7 and 1-8.
The Rectifier converts the AC input voltage from the utility
source into a DC voltage, supplying the Inverter.
The Inverter converts the DC voltage supplied from either the
Rectifier or the battery system into a three-phase AC voltage.
An AC output filter is used to achieve a computer-grade
sinewave output voltage waveform, with a total harmonic
distortion of less than 2% under linear-load conditions.
The Static Switch transfers the load between the Inverter
output and the bypass AC source without interrupting the
supply of power to the load, allowing the load to continue
operation in the event of a UPS fault. The Static Switch
circuit assures that voltage from the UPS output cannot be
fed back to the utility input lines.
The battery system stores energy for use by the Inverter. The
stored energy is utilized in the event that the AC input power
from the utility source fails, or falls outside of acceptable
tolerances. The internal Battery Charger maintains the
charge of the battery system. The DC output voltage of the
charger is temperature regulated to ensure an optimal
charge voltage. If a customer supplied battery system is to
be used, an external battery charger may be necessary.
The standard battery system is housed in a separate enclo-
sure. For systems where additional back-up time is required,
up to two (2) additional battery cabinets are available.
An external battery system can also be supplied by the
customer.
