Rugged Design for Effective Cooling N/A The Intelligent Motion series Brushless DC Axial fans ensure effective cooling via innovative multi-blade impeller designs that improve airflow performance. They also include IP51, IP54, IP56, or IP67 levels of dust and moisture protection for applications that are used in moderate to very harsh environmental conditions.
Intelligent Motion Control N/A The Intelligent Motion series Brushless DC Axial fans include full-wave in-board circuit designs with multiple features that create air movement “intelligence”. By using controls that are programmable, voltage fluctuations from power supplies are reduced, protection is enhanced, and optimum performance is ensured.

Intelligent Motion Controls improve operating efficiency and are ideal for green applications. Additional benefits include the following:
  • Improved system performance
  • Improved system reliability and life expectancy
  • Fully programmable features enable greater control and functionality
  • Multi-alarm connections to run many fans at once Intelligent Motion Controls include tachometer, rotation detection, life detection, pulse width modulation, automatic temperature control, current limit control, constant speed control, multiple alarm connections, and others. Various controls can also be programmed for custom output.
Additional Information N/A The Intelligent Motion series Brushless DC Axial Fans are well suited for applications that require high performance, maximum environmental protection, and customized control from a compact cooling device.
