KW903-SX

NMEA to Synchro Interface (low power)

The KW903-SX connects a new or replacement gyro or other electronic compass to an existing repeater system. It outputs a medium power synchro transmission with ratios 1:1 to 360:1.  Applications include refitting a ship with a new gyro, whilst retaining the existing repeaters and autopilot. Heading input is NMEA 0183 only, which most modern gyros give as standard. For gyros that do not have NMEA available, various interfaces are also available from our product range for signal conversion to NMEA data.

Advantages

  • Accepts valid NMEA 0183 input sentences used as standard in most modern gyros
  • Adjustable synchro voltage output for greater system flexibility
  • Input signal failure and output overload detection improves safety of vessel operation
  • Certified to IEC60945

NMEA to Synchro Interface (low power)

 

POWER   Nominal 110/220v 50/60Hz at 600VA. Fused, switched and filtered. Earth is essential.
INPUT   NMEA 0183 heading, magnetic or gyro or Cetrek data.
OUTPUT   Reference output nominal 55v or 110v 50/60 Hz at 1 Amp. Switch selectable. Synchro output adjustable 0 to 45 volts max at 20VA per phase. (60VA max.) Use additional transformer adapter for higher voltages. Synchro output protected against overload. Synchro frequency is normally 50/60Hz. Synchro precision 360 values per revolution at most ratios. That is 1 degree resolution at 1:1. 1/36th degree at 36:1 etc. Precision 0.05 degree at 180:1. 0.01 degree at 360:1
DIMENSIONS   300 x 400 x 150mm
APPROVALS   IEC60945
