  • 110Vdc & 220Vdc input for higher flexibility and easier spare parts management
  • Wide temperature operation for installation in harsh outdoor environments
  • Low internal temperature for high reliability
  • Active load sharing and fault tolerant output for high availability
  • Combination with high voltage rectifiers in a single cabinet for industrial and utility applications


The CDC1024TP is the perfect module to build up highly reliable multi-output energy systems for industrial and utility applications. A true constant power with 90% typical efficiency for this 1000W DC/DC converter demonstrates the combination of the long experience of Alpha Innovations for distributed power architecture with the latest developments in technology. This unique product is designed to work with a wide DC input range from 80 to 300Vdc, enabling to meet many installation requirements and making spare parts management easier.
The units are perfectly suitable for both indoor and outdoor applications and offer many features to improve monitoring and control. Beyond the traditional voltage programming and fault control, the unit is equipped with a smart derating of the power in regard to internal temperature. Signals include thermal shutdown, input range detection, over-voltage and module missing and offer great flexibility of system configuration.
Each system is protected against input under- and overvoltage, output overvoltage, smart output power limitation and over-temperature.
