Reliance W-67100-B DC Power Supply Module

W-67100-B DC Power Supply Module is a 250W DC power supply unit associated with Reliance Electric's DCS equipment. Catalogs reference the same part under alternate designations, including W/R-67100-B and WR-67100, signaling cross-listings across different product lines. Verified listings describe the device as Reliance Electric DCS W/R-67100 Power Supply 250W, with the W/R-67100-B suffix confirming the model. This item appears in multiple resale listings (Premier Equipment Solutions, eBay) as a legacy Reliance Electric component, indicating it is a historic module no longer in current production. As a DC power supply module within the DCS architecture, it would have served to deliver DC power within the Reliance Electric DCS rack system, aligning with other documented Reliance AutoMax/DCS 5000 power supply modules described in historical literature. The part numbers and alternative designations (W-67100-B, W/R-67100-B, WR-67100) are repeatedly observed in the market, providing a consistent pointer for identification across vintage catalogs.
