DC Power Supply for CNC Control – OKUMA DCPS-2
The DCPS-2 is a DC power supply module (“DC Power Supply”) manufactured by OKUMA, the Japanese CNC machine tool builder. The module is documented as a component of OKUMA’s OSP series (Open System Platform) CNC controls, where it supplies the regulated DC voltages required by the control system’s electronic boards: CPU boards, I/O modules, communication interfaces, and drive logic stages. The alternative part number is listed exclusively in the specifications table.
The DCPS-2 power supply is responsible for converting and regulating the supply voltages for all the electronic components of the CNC control. A failure of this module typically results in a complete machine shutdown, with the control unable to start and widespread alarm conditions across all axes; it is therefore a critical component for the operational availability of the machine tool.
OKUMA Corporation is one of the world’s leading CNC machine tool manufacturers, headquartered in Oguchi, Aichi (Japan), founded in 1898. It is renowned for developing entirely in-house its OSP (Open System Platform) controls, which equip its lathes, vertical and horizontal machining centres, and grinding machines. Components of the DCPS series belong to older control generations and are to be considered legacy / discontinued: availability is limited to the used, surplus, and specialist repair market.
