Proportional speed thermostatic fan control extends both equipment and fan life and reduces service calls by varying the fan speed of up to four fans, based on the temperature within the enclosure.

Featuring three temperature ranges, the fan control can be set to activate proportional to the enclosure temperature, or to come on at full power whenever the temperature threshold is reached.

Available to either mount within the company’s MPR Modular Power Raceway or as a standalone unit, the Middle Atlantic Products FC-4 is unique in design, allowing control of up to four 120 volt fans.

The FC-4’s temperature control range can easily be set to trigger automatically at 80°F, 85°F or 90°F. Fans will run at either a speed proportional to the internal temperature or automatically at full speed when the internal temperature reaches the predetermined threshold. In addition to these automatic proportional speed settings, additional settings are available, allowing for continuous fan operation or no operation at all.

Two status LED’s indicate whether the FC-4 is in AUTO or ON mode, with the ON LED blinking in proportion to the fan’s operating speed.
