DC power supply


DCC24 is a switched step-down converter, which converts DC voltage in the range 20-60 V on the input side to 13.8 V on the output side. The converter is highly efficient, generally 80 %.

The converter was primarily developed for applications where DC voltage is already available, e.g. for technology connected to RACOM modems.

Typical areas of use

  • For supplying MORSE system components: all types of radio modems, GPRS modem and other accessories in applications where 24 or 48 V DC is available
  • For separately supplying any equipment with 13.8 V and consumption up to 2.5 A


  • Resistance to reversing the polarity of the input voltage
  • Protection against short-circuiting at the output
  • Soft start
  • Minimum dimensions, assembly on to DIN rail
  • Connecting terminals for conductors with a cross-section of up to 2.5 mm2
