- Precise Speed Control: 0–10 V DC or PWM input enables seamless integration with BMS (Building Management Systems) and PLC-based control architectures.
- Low Acoustic Emission: Optimized blade geometry and EC motor commutation minimize tonal noise, critical for occupied-space HVAC applications.
- Extended Service Life: Brushless motor design eliminates brush wear; rated for continuous duty operation in harsh industrial environments.
- ErP / EcoDesign Compliance: Meets EU Regulation 327/2011 and global equivalent energy efficiency mandates for fans >125 W.
System Architecture & Signal Flow
The A4E350-AQ02-11 operates as a self-contained fan module. AC mains power (200–277 V, 50/60 Hz) is rectified and converted internally to DC by the integrated power electronics. The EC motor controller receives a 0–10 V DC speed reference signal from the building automation system or PLC output module. The controller modulates motor commutation frequency to achieve the commanded speed setpoint, providing closed-loop speed regulation independent of supply voltage variation. Fault status and speed feedback signals (where applicable) are available via the motor’s signal connector for integration into supervisory control systems.

Technical FAQ
Q: Can the A4E350-AQ02-11 be operated on a 110 V AC supply?
A: No. This unit is rated for 200–277 V AC input. Operation below the rated voltage range is not supported and will void the warranty. For 110 V applications, consult ebm-papst for an alternative model.
Q: Is a separate motor starter or VFD required?
A: No. The EC motor integrates all power conversion and speed control electronics. A 0–10 V DC control signal from your BMS or PLC is sufficient for full speed modulation.
Q: What is the expected service life?
A: ebm-papst EC fans are designed for >40,000 hours of continuous operation under rated conditions. Refer to the official datasheet for L10 bearing life data.
Q: Is this unit a direct replacement for an existing AC fan?
A: The A4E350-AQ02-11 is a 350 mm axial fan module. Mechanical fit, airflow direction, and electrical interface must be verified against your existing installation. Contact Konmask.com engineering support for cross-reference assistance.
Q: What certifications does this unit carry?
A: CE marking and UL recognition are standard. Refer to the ebm-papst declaration of conformity for the specific directives covered. Konmask.com can provide documentation upon request.
