DiY LEDs - How to Power Them

[Yesyes3000]

Hey guys what’s the best and cheapest option for drivers for these strips ? Thanks for your time !!

Hey guys. Im looking at getting some advice on low amp, +48V drivers, with dimming and if possible on/off via PWM. Most likely the driver will power 3 separate parallel strings with 0-100mA in each string so looking for something with approx 300mA max, even lower would be better cause i really think ill never be over 40mA per string, so 120mA in total.

Forgot to tag some people:
@Barristan Whitebeard has schooled me on drivers a few times
@SupraSPL and @Randomblame are better than google whem it comes to led.

Anyone has an idea? Maybe with a dc to dc driver?

Good luck, seems I can't find anything lower than 400 mA drivers anywhere myself. Sorry

Omg I'm in heaven and I've still got 222 pages to go haha

There are 350mA meanwells CC drivers with 3 in one dimming. But id love to go lower.

There are 300mA Meanwell LDDs

There are 300mA Meanwell LDDs

How do you control them? can they dim?

 

[guy_incognito251]

They can dim to off using a PWM control signal (2.5V to 6V PWM for the LDD-H) - the output is PWM when dimmed.

They are DC to DC converters though so you will need a constant voltage supply to power them. The LDD-300H can output up to 52V at 300ma - it needs a constant voltage input at least 3V higher than the output voltage (max input voltage is 56V). They are most efficient when there is a small difference between the input and output voltage.

Thats the ticket...

Hey led builders ! I was wondering if someone could help me figure out how to power these led module strips ! ? They are the F series Gen 3 and I attached the picture of the strips. Here is the link https://www.arrow.com/en/products/si-b8t521560ww/samsung-electronics?q=SI-B8T521560WW. Thank you everyone

Is this way of having leds its better? (As in quality for price) the setup is basically drivers and strips?
