Intelligent Fan Trays

The Intelligent Fan Tray features a design which uses proven control solution for each group of 3 fans within a tray. On 6 fan versions this allows for separate monitoring for each group for both control and alarm functions allowing for redundancy if required with a further option of Dual Power Input on some styles. Function of each group of 3 fans is regulated by programmed controller that operates the fans at half speed up to 35ºC and increases the speed linearly to full speed at 55ºC. Thermal control is via a pluggable thermistor sensor for each group of 3 fans. These are available in various lengths to suit its positioning within the rack, or integrated onto a bracket that fits directly to the rear of the fan tray.
