The driving force of motor control & electronics cooling. SmartFan Omni SD Speed Control for DC Fans SmartFan Omni SD is a versatile switching FEATURES DC control that operates at a high-frequency. Choose 12, 24, or 48 VDC nominal voltage ratings Units are available for nominal 12, 24 and 48 High power efficiency: typically greater than 90% VDC operation. Omni SD controllers apply a Noise reduction: typically 15 dB(A) or more at idle speed smooth DC voltage to the air mover for Constant idle voltage regardless of input voltage absolute minimum noise. Control Temperature is Optically isolated temperature alarm output sinks up to 1.0 mA set by means of a jumper on the circuit board. (normally closed) Omni SD is supplied with an optically isolated Selectable Control Temperatures of 35, 40, or 45C (74, 80, or temperature alarm, triggered if sensor 86C when P3 sensor is used) temperature reaches 10C above Control RoHS (6/6) compliant Temperature or if cooling system power is lost.
