Battery care
Max. safety and protection
The DC-UPS series is designed to
provide safe operation and long power
supply and battery life. The following
protections are standard features:
• Outputs protected against short circuit
and overload
• Outputs in conformity to SELV and
PELV conditions
• High insulation between primary and
secondary
• Protection against deep battery
discharge
• Protection against reverse polarity
connection
• Detection of batteries with wrong
rated voltage
All protections have automatic reset.
No thermal fuse to be replaced.
Robust construction and
easy installation
All the units in the range have aluminum
casing, DIN rail fastening clip and are
light and compact. IP20 protection
degree.
Technology
The new DC-UPS range is based on two
strategic know-how elements. Switching
technology, we have 25 years of
experience in design of advanced
stabilized switching technology power
supplies. A power supply/battery charger
unit based on this technology is much
more efficient.
Back UP Module and Battery Care units,
unlike most other state-of-the-art battery
chargers, the DC-UPS series is equipped
with complex algorithms which controls
the charging process and enable several
monitoring functions. The firmware
implements the extended battery care
know-how, result of many years of
experience in this field.
Norms In Conformity to:
• IEC/EN 60335-2-29 Battery chargers;
• EN60950 / UL60950;
• Electrical safety EN54-4 Fire
Detection and fire alarm systems;
• EMC Directive;
• DIN 41773 (Charging cycle)
Element in
Short Circuit
Diagnostic checks
Check for accidental disconnection
of the battery cables.
DC-UPS detects accidental
disconnection and immediately
switches off output power.
Battery not connected
If the battery is not connected the
battery output is disabled.
Test of wire connection impedance
During trickle charge the resistance
on the battery connection is checked
every 20 sec. This to detect if the
cable connection has been properly
made.
Battery in open circuit or sulfated
Every four hours DC-UPS tests of
internal impedance, while in trickle
charging mode.
Reverse polarity check
If the battery it is connected
with inverted polarity, DC-UPS is
automatically protected.
Test of battery voltage connections
Appropriate voltage check, to prevent
connection of wrong battery types.
End of charge check
When the battery it is completely full,
the device automatically switches to
trickle charging mode.
Check for battery cells in short circuit
Thanks to specific testing algorithms,
the DC-UPS recognize batteries with
cells in internal short circuit.
Battery Life Test
It guarantees battery reliability in
time by continuously testing the
internal impedance status. It avoids
any possible risk of damages and
grants also a permanent, reliable
and safe connection of the battery
to the power supply. The system,
through a battery stimulation circuit
with algorithms of evaluation of
the detected parameter, is able to
recognize sulfated batteries or
batteries with a short-circuited cell.
Temperature Compensation
In special application like fire fighting
equipment, you can recharge the
battery also with the temperature
compensation charging function, for
the best condition of your battery in
the temperature fluctuation.
