The 1U intelligent dc fan trays mount in an IEC297-1 19-in. rack, below the equipment that needs cooling. They have a maximum operating temperature of 70°C. The configurability, performance and controllability ensure that cooling is maximized while sound levels and energy consumption are minimized.
The 170-m3 /h intelligent fan trays are managed by a controller that restricts the fans at half speed up to 35°C. The speed linearly increases to maximum at 55°C. The upper and lower limits can be adjusted as required to suit the specific application. If the temperature exceeds 71°C the fans all increase to full speed and an alarm is generated. The fan tray can interface with rack management monitoring through rear mounted connections. A computer-optimized aperture pattern retains mechanical protection, maximizes airflow and reduces noise as the air passes through it.
