Total security
By combining Comet's high reliability power with the supervision of
the key parameters affecting the surrounding environment (room temperature,
access control, humidity, etc.) MGE UPS SYSTEMS offers maximum all
round security; meeting all your requirements and leaving nothing
to chance.
Genuine fault tolerant systems
With its built-in
static bypass, the priority for Comet will always be to keep the power
flowing to your application. What is more, IGBT (Insulated Gate Bipolar
Transistor) technology contributes to the outstanding reliability
of Comet, with, amongst others, the following advantages:
>
Fewer components,
> Wide component operating
tolerances to handle the most difficult situations.
Full protection of your loads
Comet offers threefold protection:
> on-line configuration
> dual input/output filtering
> shielded against radiofrequency
interference. In short, your computer system is completely protected
from external disturbances.
Unrivalled specifications
>
Active power in compliance with general market rules (power factor
given at 0.8)
> Excellent efficiency due
to low switching losses (better than 91 % for all output ratings),
> Input power factor correction
and sinusoidal current draw eliminating all harmonic pollution of
the mains,
> Choice of battery design
life (up to ten years),
> Perfectly suited to the supply
of power to computer loads without any oversizing of the UPS. As a
result, harmonic distortion at the inverter output is the lowest on
the market.
Enhanced protection with Battery Monitor
The
Comet battery offers many outstanding features:
> Charger complying with all
international standards,
> Charge cycle adapted to ambient
temperature changes,
> Protection against deep discharge,
> Precise measurement of remaining
backup time (patented by Merlin Gerin and CEAC),
> Physical separation between
battery and electronic modules.
In addition, the Battery Monitor carries out tests automatically at
regular intervals:
> Battery circuit test every
12 hours,
> Open-circuit battery test
every month,
> Partial discharge test every
3 months,
> Alarm indicating the end
of battery service life.
These tests are completely user-transparent. Only negative results
produce indications (lights on front panel, messages on Monitor Plus,
etc.). Manual tests can also be carried out by maintenance specialists.
