CNC Power Supply Unit – OKUMA OPUS 5000 RHP
The OPUS 5000 RHP is an electronic power supply module for CNC control (“CNC Control Power Supply Unit”) manufactured by OKUMA, designed for the proprietary numerical control system OKUMA OPUS 5000. The unit provides the regulated DC voltages required for all electronic boards within the control: logic boards, interface boards and axis control modules. It interfaces with the CNC main control board and axis drive modules via dedicated internal connectors.
The power supply is the fundamental component of the CNC control: without stable and regulated voltages the entire control system cannot operate. A failure of this unit causes immediate machine stoppage and renders the complete control non-functional until the module is repaired or replaced. The quality of voltage regulation directly affects axis stability and machining accuracy.
OKUMA is a Japanese manufacturer founded in 1898 in Oguchi (Aichi Prefecture), specialising in CNC machine tools and proprietary control systems (OSP series). The OPUS 5000 control belongs to the 1980s–1990s generation, now legacy / discontinued, superseded by the OSP-P series: spare parts are available only as used, surplus or through specialist repair.
