The device has a precision temperature Sensor which continuously measures the ambient temperature and sequentially switches the fans On or Off at preset temperature settings or differential steps of 2-3 degrees C.

The device has the following advantages :

  • Automatic Temperature Control of the Rack.
  • Monitors the safety of the equipment in the Rack.
  • Power Saving by selective switching of Fans.
  • Reducing load on UPS during power failure.
  • Reduction in noise levels in and around the cabinet.
  • Increased life span of the fans by reducing the duty cycle.
  • Status indication of energized / de-energized Fans on front panel

The range of Fan Tray Controllers are compact, rugged and reliable instruments designed for accurate measurement and control applications.

All ASHE instruments carry a lifetime warranty against defects in components and workmanship.
