DC SeriesMX28B1200/4800Modular, scalable DC power plant for large-sized wireless/cellular, co-location, cable andtelecommunications applications

APC’s MX28B1200/4800 system is an easily installed 23" compatible modular stand-alone power plantcapable of supplying multiples of 1200A at -48V DC. Configurableoptions allow the user to tailor thesystem for specific high integritypower requirements. The system canbe configured with up to 24 x 50Arectifiers per bay with up to 4 bays.

A Low Voltage Disconnect (LVD) canbe supplied on either battery or load side. No LVD is also an option.

A single master control unit in thefirst power system provides controland monitoring for the entire system.

The MX28B1200 can be expandedto 4800 amps with the addition ofexpansion bays.
