Siemens S30050-Q5883-X-B1/01 EWSD hardware Power Supply

The Siemens S30050-Q5883-X-B1/01 is an EWSD direct current converter module, marked M:DCCMC. EWSD (Elektronisches Waehlsystem Digital) is Siemens’ large central-office switching system, built around a central coordination processor with peripheral units that carry the lines and trunks. Siemens stopped selling it in 2017, but many operator exchanges are still in service. Converter modules in the DCC family sit in the power path of an EWSD shelf and convert the exchange DC supply into the voltages the plug-in boards need. Each DCC type is built for its own shelf position, so it is not a drop-in swap for the other DCC types. Tech-Star (UK-based, shipped worldwide) stocks Siemens EWSD spares for operators keeping these exchanges running. Send us the shelf and slot details and we will help match the right board.
