Transducers
Transducers have been employed on both
military and commercial aircraft to provide
position feedback information of flight
control surfaces to the ight computers,
autopilots and cockpit displays.

Ampliers
Amplifiers are used to
control the actuators when
the drive electronics are
located seperately outside
the actuators.
Model 871-01
150 VDC transconductance amplier
used with the Model 873 Rotary Actuator.
Model 911-01
270 VDC brushless motor controller for a
pump system on a military armored vehicle.
Model 944-01
150 VDC transconductance amplier
used with the Model 875 Rotary Actuator.
Model 962-01
150 VDC transconductance amplier
used with the Model 961 Rotary Actuator.
