Battery Charger / Rectifier MMF-ASR

The Amperis MMF-ASR battery rectifier has the most efficient technology available today.

It has a robust and reliable design for industrial applications, with the advantage of easy access and on-site maintenance.

It is a universal charger valid for all types of batteries (multi-voltage, multi-capacity and multi-chemical): ventilated lead-acid, VRLA (valve-regulated lead-acid) or nickel-cadmium. It can also be used as a power source without batteries.

The great advantage is that you have a complete set of standard load curves programmed in the factory with the possibility of creating and saving customised load curves. The MMF-ASR control boards are based on state-of-the-art microprocessors. The charger/restifier is based on standardized SCR and IGBT power converter technologies.

THE MMF-ASR CHARGER IS A RECTIFIER SYSTEM THAT COMBINES THE VERSATILITY OF THE MMF CHARGER WITH THE BENEFITS OF THE ASR RECTIFIER.

• The Amperis MMF charger is a universal, programmable, digitally controlled charger. It can work with any type of battery and support any type of application (Training, Conditioning, Recovery, Desulphation and Regeneration). It has a very complete set of charging curves (the user can program new curves).
• The Amperis ASR battery rectifier is designed to power critical DC loads or to charge any type of battery. It is based on standardized IGBT and SCR power converter technologies (in 6/12 pulse configuration) which guarantees high reliability and efficiency.

It is based on a new power conversion technology, which combines very high efficiency, unit power factor (PFC), universal capabilities and precise load control.

The MMF-ASR ensures a minimum temperature rise in the battery during the charging process, thanks to the ultra-filtered output current (perfectly constant charge current and zero ripple). It has an output blocking diode for parallel capacity, double output connectors and an output LC filter.

The power stage's convection cooling system is designed to work 24 hours a day.
