CNC Power Supply Unit – MITSUBISHI QX086
The QX086 is a switching power supply module (“Power Supply Unit”) manufactured by Mitsubishi Electric, a component of CNC systems in the MELDAS or M-series family. It provides the regulated DC voltages required by the logic, control and communication boards of the CNC system. The part number QX086 uniquely identifies the module within the Mitsubishi Electric catalogue; it is compatible with CNC control cabinets using the proprietary Mitsubishi power bus standard. Compatibility with the specific machine should be verified before installation.
The power supply unit converts mains voltage into regulated DC voltages essential for the operation of all electronic boards in the CNC system. A failure in the power supply causes the immediate shutdown of the entire control unit: the machine is unable to execute any programme or move any axis. Unstable or missing supply voltages can also damage downstream logic boards through transient over- or under-voltage conditions, making this component absolutely critical for production continuity and for protecting the other modules in the system.
Mitsubishi Electric is one of the main divisions of the Japanese industrial group Mitsubishi, active in industrial automation, CNC numerical controls (MELDAS line and M-series, M70, M700, M800) and servo drive technology. CNC products from the MELDAS series of the 1980s–1990s and early M-series versions are now legacy / discontinued: availability is limited to used parts, NOS (new old stock) and specialist repair.
