Multi SD Datasheet

SmartFan® Multi-SD is a programmable fan speed control and alarm designed for two and three wire 12V, 24V, and 48V DC fans and blowers rated up to 5 Amps.  The Multi SD can regulate the speed of one or more fans by changing the fan supply voltage in relation to a control input (temperature or 0-4VDC PWM signal).  The Multi-SD can be customized for your application using the Navigator hand-held programmer.  The Navigator can be used to create custom fan/motor speed control curves based on temperature or PWM input.  Other programming variables include: on/off set points, alarm trigger points and override speed settings.  Simply plug the Navigator into a powered Multi-SD and scroll through the 11 variable menus, selecting the control inputs for your application.  Programmed profiles can be saved and copied to multiple controllers with ease.  Factory preprogramming available for orders of 50 or more.
