Siemens DCCMC – DCC DC/DC converter power card for the Siemens EWSD digital switching exchange platform. Used/refurbished, quote-only.

The Siemens DCCMC (internal material code S30050-Q5883-X-B1/01) is a DCC (DC/DC Converter) power card from the Siemens EWSD (Elektronisches Waehl System Digital) digital switching exchange platform. EWSD is a large-scale digital switching exchange system widely deployed by network operators for public telephone network switching, and DCC-prefixed boards in the EWSD parts family supply regulated DC power to subrack-mounted line, trunk and processor cards from the exchange’s -48V DC power plant. This card is identified by the board designation “DCCMC” in Siemens’ internal parts records; DCC boards of this family are among the most commonly required spares in legacy EWSD maintenance, since a card failure directly affects power delivery to an entire subrack rather than a single interface. The precise voltage/current rating and exact host subrack for this specific board designation have not been independently confirmed, so those details are not stated as fact. Tech-Star (UK-based, shipped worldwide) stocks used and refurbished legacy Siemens EWSD hardware including this DC/DC converter card. To confirm compatibility with your specific exchange installation, or to check stock and lead time, please get in touch with our team quoting the full part reference DCCMC / S30050-Q5883-X-B1/01.
