SmartFanÃ¢ Inversion is an innovative fan speed control that combines an AC to DC power supply and a DC fan control/alarm to provide the best of both worlds; the convenience of AC power, the control and efficiency of DC fans. Typical speed controlled DC fans use 40-60% less power at reduced speeds compared to a similar AC fan. The voltage vs. flow curve of a DC fan is also more linear than a typical AC fan, making speed control more accurate. InversionÂs supply voltage range is 95 to 264 VAC. It controls 24 or 48 VDC fans with current rating up to 4.0 Amps. Variable fan speed is based on temperature or a control signal (4-20mA, 2-10VDC) input. Pricing ranges from $80 to $142 depending on volume and configuration. Benefits of using SmartFan include acoustical noise reduction, temperature regulation, greater product reliability, increased fan life, improved safety and energy savings.
