Am having trouble finding a replacement for discontinued drivers. Onboard we have constant u/i drivers for the leds. I can see they have multiple strands in series acroos several drivers for multiple circuits, as well as a 1-10v dimming section.
Currently have
constant u/i driver, 20w, 100mA-1.2a,180-240vac input.
Im having trouble putting all these options together in one module.
Any help will be greatly appreciated.
You say its output is 100mA-1.2a. Is this a programmable constant current driver you have? What is the voltage output listed on the driver? If its programmable, what current output is needed?

Morning sir,
The stated output is 6vdc to 42vdc.
If I may, please see attached photo, I believe these drivers are still avaliable, but when we world travel, I must use a supplier out of Viareggio, I’d like to find a suitable replacement in the states if possible, or just more available than Italia.The fixtures in question will use the dimmer to achieve a max output of 34±35vdc. Lowest dimmable setting takes the fixtures to 14vdc. 350-400mA.
Ive noticed that have used multiple drivers in a series, seems they are using multiple fixtures’ inputs on several single drivers to maximize thew number of dimmable fixtures.
You may need to zoom in to see better, but this is an overall idea of what they were trying to achieve.
This many in line.
On the left you can see relays for the 24vdc emergency circuit to take control of several specific fixtures during loss of 220vac normal inputs.
So I can see the driver would need that capabilities as well
Can you provide a photo of the dipswitch setting? I found a spec sheet for that unit here https://www.fulham.com/PDFs/SpecSheets/L1W1MID120D-20E--L1M1MID120S-24E--L1P1MID120S-24E--L05011i2--L05011i3--L05011i4.pdf. Page 5 shows what the current output will be depending on the setting.
Hey sir,
I apologize for my delay in answering your previous reply.
Some are set on 350 mA and some are set to 700mA. Which am I correct in assuming its related to the number of fixtures that specific one is energizing?
Also, I think interesting to note, after a power outage today, one of the cabin main room light switch now controls the restroom fixtures. Again, i’m leaning towards the reasoning being the multiple strings they are apparently all in some sort of series on.
Would it be safe to go with a 700 mA or higher to ensure I have the capabilities?
