Mean Well LPC-35-700 constant current driver

oupulino · Nov 23, 2013

Led Gurus I have a question I have hard time to find right color for my 65 gal tank I'm using Mean Well LPC-35-700 constant current driver it is possible to adjust the current on this driver example I like to run my led at 500mA
Do I have to add potentiometer or something I have no idea

Sorry but you can't adjust the current with those drivers, you'll need to get yourself a dimmable driver like a Mean Well ELN-60-48D, then you can wire in a potentiometer for manual dimming.

The ELN60 series is more suited for two parallel strings...

I would recommend The ELN30-48D as you would not have to adjust it and the 30 series will offer better efficiency at 500mA than the 60 series.

Also the ELN30-48D can drive 3-12 LEDs same as the LPC35-700. The ELN60-48 offers less flexibility at lower current as its minimum Vf is much more than the ELN30-48.

That said if your Driving 24 LEDs you can use the 60series in two parallel strings which works quite well.

Lots of driver options including dimmable Inventronics and Thompson Research...
