The Middle Atlantic Products FC-4-1CA Thermostatic Fan Control extends the equipment and fan life, and reduces service calls by varying the fan speed up to 4 fans, based on the temperature within the enclosure. Featuring 3 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.
Note: When connecting this unit to a UPS, ensure optimum performance and reliability by choosing a model that provides Pure Sine Wave output.
