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:
The voltage curves are compliant with the DIN 41773 standard, for an optimum charge allowing to extend the battery life.
AUNILEC has designed a wide range of parallel solutions to increase the general system MTBF until making it virtually infinite. Thanks to a CAN BUS communication card, in fact, the different rectifiers divide the load into equal shares, and manage a complex function exchange system.Redresseur redondant à une branche et convertisseur redondant DC/DC
Redundant single-branch rectifier with redundant DC/DC converters
The single-branch redundancy allows to keep the load and the battery powered by two parallel digital rectifiers, that by dividing the currents reduce the strain of each rectifier. The load, requiring a voltage level lower than that of the batteries, is powered through a redundant DC/DC converter.
In case of failure, the other rectifier will take on the whole load.
Double-branch rectifier with AUNILEC “EES” (Emergency Exchange System)
The equipment includes two AC/DC conversion units, that when power is supplied by the mains operate independently. During normal operation, when power is supplied by the mains, the two converters run independently. The rectifier will charge the battery, while the system branch supplies the load with a stabilised voltage with a tolerance of ± 1%. A total mains blackout or the failure of both rectifiers will automatically trigger a sequence that supplies the direct load connection to the battery.
In case of failure of one of the two branches, the other automatically starts supplying power to the load while charging the battery at a voltage equal to 110% of the rated voltage (adjustable value). Once the mains power supply is restored, the system will automatically resume operation, and each converter will return to its normal operation mode.
