Product Description

Description

The ATV21HU55N4 is a Variable Frequency Drive (VFD) within the Altivar 21 series designed to provide precise motor speed control and energy optimization for industrial equipment. This unit is rated for 5.5KW (7.5HP) operation at 480V and incorporates an integrated EMC Class A filter to mitigate electromagnetic interference in sensitive control environments. Designed with an IP20-rated enclosure, the ATV21HU55N4 facilitates efficient motor management in space-constrained cabinets, measuring 23.20 x 18.00 x 17.00 cm. This drive is part of a phased-out product line, commonly utilized for retrofitting, maintenance, and extending the service life of existing control architectures.

Features

  • Power rating: 5.5KW (7.5HP)
  • Supply voltage: 480V
  • Integrated EMC Class A filter
  • Enclosure rating: IP20
  • Compact dimensions for high-density panel mounting
  • Optimized for industrial motor control and energy efficiency

Applications

  • HVAC fan and pump systems
  • Conveyor motor speed regulation
  • Industrial pumping stations
  • Air handling units
  • Compressor control systems

Installation Guidelines

  • Ensure adequate ventilation and spacing around the unit to prevent thermal overload, adhering to the specified IP20 cooling requirements.
  • Maintain proper grounding of the drive chassis to the panel backplane to ensure effective operation of the internal EMC filter.
  • Route power and control cables separately to minimize induced noise in signal circuits.
  • When mounting in an enclosure, verify that ambient temperature conditions are within the operational limits of the drive.
  • Inspect all terminal connections for tightness before applying power to prevent arcing or poor conductivity.

FAQ
What is the primary application of the ATV21HU55N4 drive?
The drive is primarily used for motor speed control in industrial applications such as HVAC systems, pumps, and conveyor systems.
What does the IP20 rating indicate for this device?
An IP20 rating indicates the drive is protected against solid objects larger than 12.5mm but provides no specific protection against liquids; it must be installed in a suitable enclosure.
Is the ATV21HU55N4 still in active production?
No, this specific model is currently in the phase-out product lifecycle stage.
Does the drive include an EMC filter?
Yes, this unit comes equipped with an integrated EMC filter Class A to reduce electromagnetic interference.
