Product information

Description

The Rittal 3235450 fan speed controller is a rack-mounted unit for EC (electronically commutated) fans that provides sensor-based regulation to maintain target airflow and enclosure temperature. Designed for industrial and IT cabinet cooling applications, this controller automatically adjusts fan speed according to temperature or differential sensors, helping to balance cooling performance, energy consumption and audible noise in server racks and control cabinets.

Advantages

The controller enables automatic, sensor-driven modulation of EC fan speed to deliver steady temperature control without constant manual adjustment. Its rack-compatible form factor and integration with common cabinet environments simplify installation and maintenance. By matching fan output to actual thermal demand, the unit can reduce power use and lower operational noise compared with fixed-speed solutions.

Suitable for

  • Cooling of server racks and IT cabinets in data centers and telecom rooms
  • Ventilation and temperature control in industrial control cabinets and switchgear
  • Applications where dynamic regulation of airflow improves energy efficiency and noise management
  • Retrofitting existing cabinets with EC fans that support sensor-based speed control

When it may not be suitable

This controller is specifically intended for use with EC (electronically commutated) fans and relies on sensor inputs for automated regulation. It may not be compatible with conventional AC fans or systems that lack appropriate sensor interfaces. For very small enclosures with minimal heat load or for installations that require only simple on/off fan operation, a dedicated speed controller may be unnecessary.

Key specifications

  • Mounting: Rack-mounted design suitable for cabinet installation
  • Fan type supported: EC (electronically commutated) fans
  • Control: Sensor-based automatic speed regulation (temperature/differential inputs)
  • Primary functions: Automatic modulation of fan speed for airflow and temperature control
  • Application environment: Industrial enclosures, IT/server cabinets, control cabinets

How to use

Install the controller in a compatible rack position inside the cabinet following cabinet layout and ventilation planning. Connect EC fans to the controller using the specified fan connectors and wire the temperature or differential sensors to the appropriate inputs. Configure sensor thresholds and control parameters according to the enclosure’s thermal profile so the controller increases or decreases fan speed in response to measured temperatures. Verify operation during initial commissioning by monitoring fan response across expected temperature ranges.

What to consider before purchase

  • Confirm fan compatibility: ensure your EC fans support sensor-based speed control
  • Check cabinet space and rack mounting requirements for proper fit
  • Ensure available sensor types and wiring in your system match the controller inputs
  • Evaluate thermal load to determine whether automatic regulation will provide benefits over fixed-speed fans

Usage recommendations

For reliable performance, pair the controller with EC fans from the same or compatible product families and use temperature sensors placed where they represent the critical temperature of the equipment. Periodically inspect sensor wiring and fan connections, and adjust control thresholds after operational testing to balance cooling, energy use and noise levels.
