DC Power
Battery charger unit, rectifier
CN.D
CN.D chargers are designed to charge 12V to 48Vdc battery or maintain larger battery used for Genset starter or fire pumps Self.
They can also be integrated in box to provide power supplies with backup for process control systems, or to LV/MV switchgears.
Advantages
- A robust charger batteries unit, secondary switch mode technology, adapted to the difficult industrial environments, supplemented effective protections increase its reliability
- Charger units for integration in cabinet providing performances and data with high quality level (regulation, reliability, short circuit proof..)
- A clear indication (three indicators and a report alarm) and a good accessibility give fast maintenance
- Small overall dimensions facilitate its integration
- Second voltage (Egalisation mode) for electrolytic cells batteries (Pb open and CdNi).
