RODUCT ESCRIPTION
The SAFE 328 is an avionics cooling fan that provides an operating indication. When the fan is normally
operating, this output is at low impedance. The output goes to high impedance whenever the RPM of the
motor drops below a preset threshold, signaling the connected avionics of the reduction in cooling from the
SAFE 328.
