The design has to be compliance with DO254 -Airborne Electronic
Need:
A- protection circuit for PWM modulated LED strings.
B-Eyes protection circuit for IR ( Infra Red ) sync pulses transmitter for 3D viewing system.
The circuits shall be design according to "Sail Safe" guidelines & contains fall back / return back features
A-Supply strings voltage 36 [VDC]
Momentary current 5 [A]
The maximum power allowed is 50 [watt] per TBD cycles.
Note:the main power supply is the new 9-36VDC input, 12VDC/10A output
,1/8 brick of Murata UWE-12/10-Q12N-C
The circuit has to prevent damage to the LED strings in case of malfunction.
B- the IR sync transmitter is using the powerful Osram SFH 4725S
The circuit has to prevent a damage to the operators eyes in case of malfunction
