The TCAC001 is a thermal control unit that works in conjunction with thermally controlled fan trays to turn them on and off or ramp fan speed up or down depending on the cabinet temperature.

The OA11/22CB is a dual output unit that controls fan speed for single or multiple fan assemblies. It also enables precise control of fan noise, speed, and air delivery according to application requirements. Three factory presets (user adjustable) allow for maximum flexibility with minimum setup time.
