Sanyo Denki Fan Speed Controller for Use with Fans, 7 → 60 V dc, 5 Speeds

Note for thermistor and external adjustment control a suitable thermistor and potentiometer must be ordered separately. See stock number ; 697-4556 697-4556 for a typical thermistor and stock number ; 729-3426 729-3426 for a typical potentiometer. San Ace PWM Fan Controller. The San Ace PWM fan controller fills a gap in the market for a dedicated unit capable of controlling PWM fans by various control functions. It generates a PWM output signal from four possible types of inputs. These possible functions are: Voltage control (0-5 V dc) Internal adjustment (using the adjustable knob) External adjustment (with a suitable potentiometer) Thermistor control (using the adjustable knob with an external thermistor connected) Only one input option can be selected at a time however the unit can control up to four fans. This unit can be common-powered by the fan power supply of rated voltages 12 Vdc, 24 Vdc and 48 Vdc. This eliminates the requirement for a separate power supply reducing overall costs. By controlling the fan speeds and only having them running at the required power, the overall power consumption of the circuits are reduced further reducing operational costs. Features. Reduces system power consumption Reduces unnecessary fan noise Maximum of four fans connectable Can be common-powered by the fan power supply Multiple input functions can be used Simple to use control knob and function selector DIN Rail mounting or screw mounting
