Hi all, 1st post...
I have a product that is close to finalising, but I'm having trouble locating suitable cable. For background, this is a 14,000 lumen Flarm controlled unit for airborne conspicuity (in Europe, this is a GPS + 868MHz relative location device that signals the presence of other aircraft). The main unit employs a buck-boost converter for driving the LEDs (8 in total) at a 44Khz PWM. PWM peak current is approximately 6A, but the duty cycle and flash rate sees a wire rating of less than 3A. This needs to be connected to the LED flasher unit that is attached to the Glider plexiglass canopy.
I've been searching for a suitable cable to connect the main board that is screened & contains 2 x < 17AWG (>1.15mm2 diameter cables), with the other 3 being of smaller diameter (they are for 3v3 sensing and indicating functions). It would be ideal if the 2x<17AWG were independently screened. Yes, I have a heap of pre-compliance testing to do (shame that the EMC option on my DSA815-TG ran out…).
A number of suitable cables have emerged since the USB-PD standard came on the scene, but the usual suppliers (Digikey, Mouser, etc.) don’t seem to stock any. I’ve scoured the internet, including AliExpress to no avail.
Any thoughts?
