  • 95.5% efficiency  
  • Operating from -40°C to 80°C
  • Compatible with CAR0948TN and CAR1048TN
  • Universal wide AC input
  • Wide DC input up to 408Vdc 


The ECOR1048TN 1000W feeds DC power and enables the infrastructure management of telecom access nodes with one the lowest total cost of ownership of the market. Backward compatible with the former generation of 850W and 1000W rectifiers (CAR0948TN and CAR1048TN), it brings further savings of multiple tens of Euros on the energy bills and maintenance. Combined with the ACE and CAPTIN systems, it creates a wide range of opportunities for highly reliable controls of costs in energy consumption, load management, environmental operating conditions, inventory management, site maintenance and intervention.
In addition to a heat dissipation cut by half compared to the former generation, the ECOR1048TN 1000W operates up to 80°C with full rated power output up to 65°C, bringing further savings in the thermal management design of cabinets and cooling costs.
The rectifiers are designed to last far beyond the life cycles of many data and telecommunication equipment. Redundancy diode on the output allows for hot-swap fault-tolerant insertion. The  unit is protected by a smart output power limitation and also protected against over-temperature, input undervoltage, input overvoltage (up to 280V without damage) and output overvoltage. A rigorous selection of the components and advanced thermal management design support the excellent MTBF of 500 000 hours calculated per Telcordia SR-332 RPP standard and an estimated life expectancy of more than 14 years.
