Overview
|
Designed for standard electric trim servos, the Safety-Trim Intelligent Servo Controller (Safety-Trim) is an electronic speed control system for experimental aircraft. Safety-Trim provides the directional switching function as well as the adjustable speed control function needed to drive electric trim motors with a time limited operation of the trim servo motors that reduce the possibility of run-away trim and failure to operate conditions. Safety-Trim is an important safety feature that is short circuit proof and reverse polarity protected. 2 speed preset models are set for high and low speed trim actuation that allow separately adjustable trim speeds for different flight configurations. The single axis heavy-duty model is for DC trim motors and linear actuators rated for operation at 12 volts and up to 10 amp. |
