Page 7: Introduction
KW903-SP. This SX model is the answer for gyro repeater systems with 90X and 36X etc. The KW903-SX is also an answer for 360:1 system for very smooth and precise control of a repeater, such as in an autopilot. -
Page 8: Specifications
AMI Manual KW 903-SX Doc No: AMI TM903-SX Issue: 4 CLASSIFICATION: Commercial In Confidence SPECIFICATIONS INPUT: NMEA 0183 heading, magnetic or gyro or Cetrek data. OUTPUT: Reference output nominal 55v or 110v 50/60 Hz at 1 Amp. Synchro output adjustable 0 to 45 volts at 20VA per phase. -
Page 9: Installation And Test Guide
If the reference voltage output is too high the synchro repeaters may burn out. USE OF TRANSFORMER ADAPTER The KW903-SX only produces up to about 45 volts maximum between phases. Anschutz repeaters require 20 to 24 volts phase voltage so the KW903-SX may be used directly. CLASSIFICATION: Commercial In Confidence... -

The alarm must be an independently powered unit. The KW903-SX has no feedback from its synchro output, so it cannot know if the output has failed. AMI’s range of heading repeaters, off course and compass comparator alarms are best used to independently monitor the synchro transmission. - Page 13 AMI Manual KW 903-SX Doc No: AMI TM903-SX Issue: 4 CLASSIFICATION: Commercial In Confidence KW903-SX3 SYNCHRO TRANSMISSION UNIT PRINCIPLES AND TECHNICAL NOTES MICROPROCESSOR CONTROL. It is the program in EPROM which make the device work at all. The EPROM must be changed to give different ratios of synchro output.
