Mitsubishi MAZAK QX084 Power Supply for MELDAS 500 CNC
The Mitsubishi MAZAK QX084 is a specialized power supply module designed to provide stable and regulated DC power to the MELDAS 500 series CNC control systems, commonly found in MAZAK machining centers and turning machines. This power supply unit is a critical component that ensures the entire CNC system—including the main processor, servo drives, and I/O interfaces—receives clean, uninterrupted power for optimal performance and longevity. The QX084 is engineered to meet the rigorous demands of continuous-duty machining environments.
Built with high-grade electronic components and advanced thermal management, the QX084 delivers consistent output voltage even under fluctuating line conditions. Its compact form factor allows for direct mounting within the CNC electrical cabinet, minimizing wiring complexity and reducing overall footprint. The unit features comprehensive protection circuits that guard against overcurrent, overvoltage, and short-circuit faults, thus protecting sensitive control boards from damage.

Key Functional Features
Active Power Factor Correction (PFC): Ensures near‑unity power factor, reducing harmonic distortion and improving overall energy efficiency.
Overload and Short‑Circuit Protection: The unit automatically shuts down or enters current‑limit mode in case of an overload, resetting once the fault is cleared.
Thermal Monitoring: An internal temperature sensor prevents overheating by reducing output or triggering a fault alarm if the ambient temperature exceeds safe limits.
LED Status Indication: Front‑panel LEDs indicate input power presence, output voltage status, and fault conditions for quick visual diagnostics.
Soft‑Start Function: Limits inrush current during power‑up, protecting the main circuit breaker and reducing stress on internal components.
Integration with MELDAS 500 CNC Systems
The QX084 is specifically calibrated to interface with the MELDAS 500 series control architecture, ensuring voltage rails match the requirements of the CNC main board, servo amplifiers, and auxiliary devices. It connects via standard terminal blocks and includes a dedicated grounding terminal for noise suppression. The module communicates with the CNC system through a status relay contact, allowing the control to monitor power supply health and initiate orderly shutdowns in case of anomalies.
Compatibility extends to various MAZAK machine models, including vertical machining centers (VMC), horizontal machining centers (HMC), and multi‑tasking lathes. The power supply is designed to operate in conjunction with the MELDAS 500 servo drives and spindle drives, forming a cohesive power distribution network.
Typical Application Environments
Aerospace component manufacturing: Powering high‑precision 5‑axis machining centers.
Automotive production lines: Supporting heavy‑duty milling and drilling operations.
Die and mold making: Supplying reliable power for complex contouring and finishing.
General job shops: Retrofitting or maintaining older MAZAK machines with the QX084 as a direct replacement.
Installation and Maintenance Guidelines
Mounting the QX084 requires a standard DIN rail or screw‑down base inside the control cabinet. Ensure adequate clearance around the unit for airflow—minimum 50 mm on all sides. Input and output wiring should be sized according to local electrical codes, using stranded copper conductors with appropriate insulation ratings. Periodic inspection includes verifying terminal tightness, checking for dust accumulation on heatsinks, and confirming LED indicators are within normal parameters. The unit is designed for long‑life operation with no user‑serviceable parts; any failure should be addressed by qualified service personnel.
Environmental and Compliance Standards
The Mitsubishi MAZAK QX084 is rated for operation in ambient temperatures from 0°C to +50°C, with relative humidity up to 90 % (non‑condensing). It complies with EN 61000‑6‑2 (immunity) and EN 61000‑6‑4 (emissions) for industrial environments, and carries CE marking. The module is also RoHS compliant, limiting hazardous substances.
Conclusion
The Mitsubishi MAZAK QX084 power supply is a robust, reliable, and precisely engineered component essential for the stable operation of MELDAS 500 CNC systems. Its combination of advanced protection features, high efficiency, and seamless integration makes it the preferred choice for maintaining the performance and accuracy of MAZAK machine tools in demanding production settings.
