Ethernet connectivity.
Optional FALCON battery control system.
“H class” input isolation transformer.
Power supply systems for
industrial environments:
RDC, the battery charging rectifier, is an energy
converter for industrial use designed to ensure a
constant power supply in association with the batteries.
Using different types of connections and operating
criteria, and building on the experience gained in the
last 40 years, our partner can fulfil any request while
ensuring a high system efficiency.
The series of rectifiers and battery chargers for
industrial use is based on total control 6- or 12-pulse
thyristor bridges. We can supply a wide range of
systems with voltage output from 24 V DC to 220 V
DC and current output up to 1000 A. The equipment is
installed inside stand-alone, self-supporting cabinets.
The frame and the panels are made of steel. The
protection degree is IP 30 (up to IP42 upon request)
and IP 20 when the panels are open; access to the
equipment is from the front.
The equipment is designed, manufactured and tested
in compliance with the applicable IEC regulations.
The graphical display allows to choose
between 4 different charging modes:
-t Rectifier only
-t Equalised charging with temperature
compensation
-t Quick charging activation
-t Manual and battery forming charging
The voltage curves are compliant
with the DIN 41773 standard, for an
optimum charge allowing to extend the
battery life.
