Standard 48Vdc Power System
Part Number: 053-991-20
|
 |
 |
- 48Vdc systems using high density 1.8kW rectifiers
- Front access DC connections
- Integrated CXCM2 modular digital controller
- Wide range AC input
- Optional integrated systems with battery trays
- Integrated system shunt and LVD
Alpha CXPS standard power systems bring proven Cordex technology into a standard integrated system package. The CXPS 48-1.8-M2 uses high density 48V-1.8kW rectifiers, a front access distribution center, and the advanced, modular CXCM2 controller.
The CXPS 48-1.8-M2 is a perfect solution for various small to medium-sized 48Vdc applications, and with a small footprint and high temperature operation is ideal for outside plant installations. The system provides up to 262 Amps of 48Vdc power, and includes 14 load and 4 battery breaker positions along with a low voltage battery disconnect and shunt.
The system is a universal 19" or 23" rack mount design and can be easily integrated into various racks, boxbays, or enclosures. The system can also be ordered factory-installed into various Alpha rack configurations including systems with pre-wired battery trays.
