Re: I need a small, cheap 277vac to 12vdc LED driver

I meant incorporate the IC LED driver on a board with whatever other components needed, wired correctly, and installed in a small box with input and output leads. I would imagine there would be decent demand for inexpensive auxiliary LED (plug and play - or close to it) lighting for 3 phase producti...

Re: I need a small, cheap 277vac to 12vdc LED driver

I would love to find that driver in a package I could use. Probably still out of my league figuring out how to incorporate it myself.

Re: I need a small, cheap 277vac to 12vdc LED driver

This project may not be as simple as I was expecting. I am out of my depth with designing a circuit to pull this off. I may just wire the driver up and see what happens. I just need to figure out how many LEDs to keep in the strip lights.

Re: I need a small, cheap 277vac to 12vdc LED driver

I just got 2 of these for $10. http://cgi.ebay.com/ws/eBayISAPI.dll...L:COSI:US:1123 These are what I had in mind to power the LEDs and be fed off one leg of the 3ph 460v 60Hz power already at the machine. I thought it might be best to scrub off a few volts to get within range of the transformer. If...

Re: I need a small, cheap 277vac to 12vdc LED driver

I meant to place the resistor between 277v and the LED driver (85-240vac input, 12vdc output).

I need a small, cheap 277vac to 12vdc LED driver

I need to find an inexpensive way to run some 12vdc LED work lighting on 480v 3ph equipment. Problem is - all the small transformers/drivers take from 80ish to 240ish vac. I am only looking for about 1w. My idea is for the lights to come on with the machine - wired into one of the 3ph legs. Is it ko...
