Control up to three Fannies per Speedie using the barrel connector outputs or switch the internal 10A fuse to the secondary position to enable the output terminal and control any other 12VDC fan. This model Speedie has the fan speed control knob mounted to the chassis with no display. If you are looking for the version with the remote knob and display, check it out here: Speedie 12V Fan Speed Controller with Remote Mounted Display. Speedie uses Pulse Width Modulation (PWM) to digitally control fan speed and is safe for all 12VDC fans.
NOTE: Please use the appropriate gauge wire for the auxiliary fan you’re powering.
