Am looking for recommendations for a power supply for panel backlighting and instrument lights.
I'm particularly interested in a 6V with high amp power supply. Hopefully, using only 1 supply but am not against using more than 1, if need be, and suspect this may be the requirement here.
Any suggestions or recommendations?
Most backlight is runned on 5v.
I have one 5V 15 amps and one 5V 8 amps for all my backlights.
They are pretty cheap.
Are you planning on making the backlights adjustable? That could change things for you.
I run 12Vdc LED Light strips throughout my pit, controlled by 12Vdc LED Light Dimmers
LED Dimmers (https://www.amazon.com/gp/product/B08BJ1KHSK/ref=ppx_yo_dt_b_asin_image_o08_s00?ie=UTF8&psc=1)
Here's the supply I use: (Very sturdy, clean power.)
Meanwell 12Vdc 30 Amp power supply (https://www.amazon.com/LRS-350-12-Switching-LRS-350Series-MEAN-WELL/dp/B07BK2G6K8/ref=sr_1_6?dchild=1&keywords=meanwell+12v+power+supply&qid=1615502072&sr=8-6)
If you're driving 5v LEDs, You could still use the 12Vdc supply & dimmer(s). Just use a 1K resistor in series instead of the usual drop-down values (270-330-470 ohms)
That's the same unit I bought from Amazon for the same purpose. Works great.
Thank you very much for the replies.
My apologies for the delay in replying sooner; I've been in the process of selling a house and looking for a new one to buy. Always a time-consuming and stressful process!
My project, Boeing 727-200, will be using OEM panels, instruments and assorted components as much as possible.
OEM lighting is fitted with GE 328 lamps/bulbs at 6V, .20amps each. Given this, the engine instruments panel alone have a total of 45 individual lamps/bulbs (3 in each gauge), pulling a total of 9 amps.
I haven't calculated the main instrument panels, overhead panels nor the second officer's panels yet. All panel backlighting indicates 5V.
All lighting is dimmable via rheostats located on the overhead panel.
I have recently purchased a throttle quadrant (VERY rare find) and will be dismantling, cleaning and lubricating it soon, then comes the addition of electronics for interfacing.
All-in-all, a fun yet frustrating project.
I appreciate the input from all.
