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

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.

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

Note for thermistor and external adjustment control a suitable thermistor and potentiometer must be ordered separately. See stock number 697-4556 for a typical thermistor and stock number 729-3426 for a typical potentiometer.

Keep your fans up to speed with this PWM speed controller from Sanyo Denki. As you can connect it directly to your system without the need for new circuits, you can cut back on installation time to get things up and running in a jiffy. The simple-to-use knob lets you quickly change between five speed settings to suit the needs of your application. Its low power consumption of just 0.2W means you can keep things running smoothly without any wasted energy.
