Information
2.1 General
The SN3308 is enclosed in an ARINC 408, 3ATI form factor enclosure and is
mounted to an instrument panel using a specially designed clamp tray fixture
containing provision for up to three captive D-Sub 37 pin connectors. A black bezel is
standard which accepts a cosmetic bezel mounting adapter for customization to an
appearance similar to a Bendix/King KI-525 series PNI.
The SN3308 operates on an input voltage from 11 to 33 Volts DC and requires 3.3
amperes of current at 11 Volts DC when the AMLCD display is operating at maximum
brightness. Also, 26 Volts AC, 400 Hertz reference excitation 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 must be obtained from the aircraft inverter source.
The following section describes the technical characteristics which include the
appliance approval basis, physical and electrical properties, electrical connector pin
allocation which details function and gradient or equipment protocol, and ARINC label
support. Also included is the description of the SN3308 installation components,
other equipment and installation requirements. A review of the installation approval
procedures is provided for filing with authorities.
