Schneider Altivar 11 ATV11HU09M2U Variable Frequency Drive

Description

The ATV11HU09M2U is a compact variable speed drive (VSD) from the Altivar 11 series, specifically engineered for the reliable control of small three-phase asynchronous motors. Rated for 0.37 kW and powered by a 230 V single-phase (1-phase) input, this drive is tailored for light-duty automation tasks where space is at a premium. The unit features an IP20-rated enclosure, making it suitable for mounting within protected electrical cabinets. It provides essential motor control functions, such as smooth acceleration and deceleration, which help reduce mechanical wear and improve overall energy efficiency in small-scale machinery.

Features

• Optimized for 0.37 kW low-power motor applications.
• Compatible with 230 V single-phase power supply.
• Compact Altivar 11 architecture for efficient cabinet space utilization.
• IP20 ingress protection for indoor industrial use.
• Precise and reliable speed regulation for basic motor-driven equipment.

Applications

• Small commercial blowers and fans.
• Laboratory mixers and small stirrers.
• Light-duty conveyor systems.
• Specialized equipment requiring basic speed adjustment.

Installation Guidelines

• Mounting: Mount the drive vertically on a flat surface inside a protected enclosure to ensure proper heat dissipation.
• Ventilation: Maintain adequate vertical clearance above and below the drive to facilitate airflow through the cooling vents.
• Wiring: Connect input power and motor leads strictly according to the wiring diagrams provided in the technical documentation.
• Grounding: A robust earth ground connection is essential for safety and to minimize electromagnetic interference (EMI) within the control cabinet.
• Maintenance: Since the ATV11 series is obsolete, regularly inspect the internal cooling fan and terminal connections; for critical production lines, consider evaluating a replacement model from the current Altivar range.
