Digital static UPS unit 1Ph or 3Ph
DPS
One line Diagram
Main features:
Double rectifier 125 Vdc 1250A
Double inverter 125 Vdc 100KVA
Change over switchboard
installed in Hassi R Mell Solar Plant
(Algerian desert)
High flexibility, allowing our
equipment to adapt to all
system features
The DPS is suitable for a wide range of applications
in the most demanding industrial environments. It
allows to achieve complex system architectures
to ensure maximum power
availability with a wide range of
accessories and optional. We
can supply redundant N+1 or
HOT STANDBY configurations.
Thanks to the new our DIGITAL
TECHNOLOGY, you can
choose different alarms with
voltage-free contacts, with a
wide range of LED indications
and accurate digital measurements.
Furthermore a graphical display shows
measurements, alarms and a one-line diagram to
help the operator to better understand the situation.
The digital inputs can be customised according
to specific customer needs, allowing to take into
account special system statuses and to display
them on the monitor. The display can store the
alarm list and an event history.
You can adapt the DPS to the technical
specifications. Should you need any particular
applications and customised solutions, please
contact AUNILEC.

To ensure its compatibility with
the most demanding applications, the Aunilec DPS system
can withstand a high short-circuit
current, in order to guarantee
the selectivity of the downstream
protections. The fully DIGITAL microprocessor logic controls the power conversion,
supervises operation, supports the system and
modifies the parameters in case of component failure to
assure power supply to the load.
If the load is highly distorted, the high frequency switching and
the DPS loops support the system by keeping THD low. The
Aunilec digital UPS units are fitted with a modern IGBT technology and a PWM modulation allowing to obtain a pure sinusoid
output wave as required by the strictest standards contained in
IEC EN 62040 class VFI-SS-III.
Ventilation may be redundant, allowing to keep a rated output
load only using one half of the fans. The air flow sensors detect
the ventilation drop and immediately trigger an alarm, allowing
to replace the damaged fan.
