SmartFan Inversion control combines an AC-to-DC power supply and a DC fan control/alarm. The design is intended to provide the convenience of AC power and the control and efficiency of DC fans. The control's supply voltage range is 95 to 264 VAC. It controls 24 or 48 VDC fans with current rating up to 4 A. Variable fan speed is based on temperature or a control signal (4 to 20 mA or 2 to 10 VDC) input.
