Figure 1 Now higher current does make the LED brighter, but it also will eventually over-drive the LED. You find the maximum output voltage of the driver in this mode with this formula: 48VDC – Vin So when using a 12VDC power supply and the XPG2 LEDs from above That being said, when sticking with low voltage drivers and going through a transformer, the system is only as good as the power supply.

I highly recommend AC drivers in cases like these along with LED retrofits. If you want to dim from line voltage with popular Lutron dimmers then Phihong's TRIAC dimmable line, like the AC LED drivers eliminate the need for the added components. More hints
A big advantage with AC drivers, especially with the new Phihong line, is line voltage dimming. Since the current is divided equally among the strings, you could use a driver that has an output as high as 2000mA. 3. Output current: 290mA ± 5%.
Thanks. Not only this but with the AC option I can also dim through line voltage dimmers. AC Electronics has a variety of Constant Current LED Drivers in stock and customizable with various Watt sizes (5 Watt, 12 Watt, 21 Watt, 24 Watt, 27 Watt, 30 Watt, 40 Constant Current Led Driver Md Led-d35-2 Today, it seems ‘LED driver' and ‘LED power supply' are used interchangeably.
Using them will also make the wiring look more professional. Constant Voltage Led Driver You can find your LEDs forward voltage by checking it on the product pages or data sheets.

for the 20mA I have the 3023-D-E-700, or can I use this for both situations? http://www.ledsupply.com/blog/understanding-led-drivers/ You can see that in general lighting situations like these it will be cheaper to run a driver from 110-240VAC. Now cheaper is not always better, but in this situation, that is Constant Current Led Driver 700ma In the rest of this post, however, we will go over why AC LED drivers, or off-line drivers, are beneficial and how they can cut down on the size and cost Constant Current Led Driver Circuit VLED15 Series 15 W, Single Output, Constant Current LED Driver, Ac-Dc Power Supply PLDA25 Series 25 W, Single Output, Dimmable, Constant Current, Ac-Dc LED Driver Power Supply PLDA40 Series 40 W,
Many AC drivers have integrated 0-10V dimming, this is low voltage dimming so wires come from the driver to the dimmer in order to dim the LEDs. get redirected here Constant Current LED Drivers vs. All Rights Reserved. Important note if you are using a parallel circuit! Constant Current Led Driver Dimmable
This PCB use CN5611 IC, 80-800mA adjustable. constant voltage here. With this dimming type you will have your line voltage dimmers and then the driver and LEDs coming off of that. navigate to this website Now, it's known that LED drivers are considered constant current devices, so why do manufacturers offer constant voltage drivers for LEDs as well?
LED Power Supply Selection TRC Electronics is the authorized USA stocking headquarters for MEAN WELL constant current LED power supplies. Constant Current Led Driver Ic Output Voltage (DC) Range Voltage range is a very important part when working with line voltage drivers.

DC Dimming Low voltage DC powered drivers can be easily dimmed in a couple different ways. The excess forward current would result in extra heat within the system, cut down on the LEDs lifespan, and eventually ruin the LED. Thankfully there are constant current drivers that take AC power directly and then give off a constant DC current with a safe voltage range for the LEDs to operate in. Dimmable Led Drivers Cost will be lower as well as the total number of components which makes connecting under the same dimmer much more simple.
All you need to do is pick a shape and size that works well for your setup. With high power LEDs running around 2-4 volts, most AC drivers do not have low enough voltage ranges to power just one or even two LEDs. Constant Voltage” Pingback: Understanding LED Drivers by LEDSupply Leave a Reply Cancel reply Your email address will not be published. my review here With a constant current source, even as the voltage changes with temperature the driver keeps the current steady while not over driving the LED and preventing thermal runaway.
Whereas if you were using the Cree XP-L, which can be driven up to 3000mA, you would not have this problem and could use any of our drivers, including this 72W Call: 1-888-612-9514 Business Hrs: Mon~Fri 8:00am~7:00pm EST LED Power Supply Links LED Power Supplies - C.V.

Your second option for dimming is to use a 0-10V wall dimmer, like our A019 Low Voltage Dimming Control. The AC Dimming Advantage With LEDs, dimming is done in a variety of ways. It will not be flashing at all but will gradually increase to the continuous forward current and decrease over long periods. All Rights Reserved.
Looks like I selected a driver that will work! 5. LED drivers come in a wide range of sizes; in small rectangle forms, longer butterstick styles, and also puck style drivers. The most common LED strips are designed with a group of LEDs in series with a current-limiting resistor in line with them. Universal AC input / Full range (up to 295VAC).
