CNC Control Power Supply Module – OKUMA OPUS 5000 RLP
The OPUS 5000 RLP is a regulated logic power supply module for CNC control (“Regulated Logic Power Supply Module”) manufactured by OKUMA, a component of the OPUS 5000 CNC control system fitted to OKUMA machining centres and CNC lathes produced during the 1980s and 1990s. The module generates and distributes the stabilised DC voltages required to power the logic boards, processors and interface circuits of the CNC. It is classified as a power unit internal to the control rack, distinct from axis or spindle drives.
The power supply is the energy core of the numerical control unit: it continuously and reliably delivers working voltages to all CNC logic modules. A fault in the power supply causes an immediate shutdown of the entire machine, as without the correct supply voltages no control board can operate; typical symptoms include axis position loss, undiagnosable alarms and inability to start the machining cycle.
OKUMA Corporation is one of Japan’s leading CNC machine tool manufacturers, founded in 1898 in Nagoya. It designs and builds both the machines and its own numerical controls (the OPUS series, succeeded by the OSP – Open System Platform), ensuring full vertical integration. The OPUS 5000 series is legacy / discontinued: spare parts are available only as used stock, NOS surplus, or through specialist repair services.
