2.1 General
The SN3500 is enclosed in an ARINC 408, 3ATI form factor enclosure and is
mounted to an instrument panel using a standard ATI clamp. A black or grey bezel is
provided.
The SN3500 operates on an input voltage from 22 to 33 Volts DC (11 to 33 volts DC
on units with serial number 5-2500 or higher), nominal 35 watts. One or two 26 Volts
AC, 400 Hertz reference excitation inputs with a current requirement of less than 1
milliampere is required when the functions of AC synchro inputs or outputs are
required for use with peripheral equipment. This reference excitation signals must be
obtained from the aircraft inverter source. A third inverter input (‘Datum Excitation’ is
available specifically used in situations where the autopilot uses an additional inverter
or the autopilot inverter frequency is higher than 400Hz.
