Custom Fan Tray Design – Fan Tray Assembly for Telecom Cooling

Control Resources specializes in custom fan tray design with integrated SmartFan Speed Controls and Alarms. This custom fan tray design features two 24 VDC, 50 Watt fans packaged with a custom SmartFan Multi SD fan speed control and alarm. Power and signal connections are through a Molex BMI connector. The fan speed control board circuitry includes hot-plug capability for fan tray insertion. The painted front panel includes two LEDs powered by the fan speed control board to indicate fan status. A captive thumb screw allows easy fan tray attachment to the chassis.
