Key Features and Technical Specifications

• Motor Type: Brushless DC motor – offers low maintenance and extended service life.
• Power Rating: 12 V, 3.5 A – ensures efficient operation without excessive current draw.
• Operating Voltage: 12–14 V – compatible with standard automotive electrical systems.
• Control Interface: Integrated push‑button switch or remote control via vehicle’s central console.
• Mechanical Design: Compact housing with reinforced gear train to withstand repeated use and resist wear.
• Safety Features: Built‑in overload protection, reverse‑direction detection, and automatic stop at window limits.

Performance Characteristics

The AC264 is engineered for consistent performance across a wide temperature range. Its brushless motor provides high torque density, enabling the winder to lift heavy glass panels smoothly even in extreme cold or heat. The regulator’s gear system is calibrated to minimize backlash, resulting in precise window positioning and minimal vibration.

Installation Compatibility

This unit is designed for front windows of a broad spectrum of vehicle models, including those from major manufacturers such as Renault, Dacia, and other European brands. The AC264’s modular design allows it to fit into existing door assemblies with minimal modification, making it suitable for both OEM replacements and aftermarket upgrades.

Design and Build Quality

The AC264 features a robust aluminum housing that protects internal components from moisture, dust, and mechanical shock. Its sealed gear train prevents ingress of contaminants, while the motor’s bearings are lubricated with high‑quality grease to reduce friction over time.

Aesthetic Integration

With a sleek, low‑profile profile, the regulator blends seamlessly into modern vehicle interiors. The external casing is finished in matte black or silver, matching common door panel colors and providing a subtle yet sophisticated look.

User Experience and Operation

Drivers and passengers benefit from the AC264’s quiet operation; noise levels are typically below 55 dB during normal use. The regulator responds instantly to button presses, offering a smooth start and stop that enhances overall cabin comfort.

Safety and Reliability

• Overload Protection: Detects excessive load and automatically shuts down to prevent motor damage.
• Reverse‑Direction Detection: Stops the window if it attempts to move beyond its mechanical limits, safeguarding glass integrity.
• Temperature Compensation: Adjusts motor performance based on ambient temperature to maintain consistent speed.

Maintenance and Longevity

The AC264’s brushless design eliminates brushes that wear out over time, reducing routine maintenance. Periodic inspection of the door seal and cable routing is recommended to ensure optimal operation. When properly installed, the regulator can reliably serve for many years without significant degradation.

Environmental Considerations

The unit complies with automotive environmental standards, featuring recyclable materials where possible. Its efficient motor design reduces overall vehicle power consumption, contributing to better fuel economy and lower emissions.

Applications Across Vehicle Models

While the AC264 is specifically engineered for front windows, its versatile mounting system allows adaptation to various door configurations. It has been successfully integrated into:

• Front passenger side doors in compact cars.
• Driver side doors in mid‑size sedans.
• Rear doors of certain hatchback models (with minor modifications).

Conclusion

The Magneti Marelli AC264 Front Window Winder exemplifies the blend of precision engineering, durable construction, and user‑friendly operation. Its advanced motor technology, safety features, and compatibility with a wide range of vehicles make it a standout choice for anyone seeking reliable electric window performance.
