Powering LED through Terminal Block

[iVVChewy9141VVi]

Recently purchased the BU0836X with all the LED i need to use for my creation i have to look into using a PSU with a Terminal Block. Has anyone did this? Or have anyplace to help me do this?

 

Are there ways or terminal blocks that can use a wall plug to power the terminal block?

[iVVChewy9141VVi]

Anyone have ideas how i would do that. Would i need something like this?

Hi, Can you post the specs of your LED's voltage/amp and how many you are going to run?

Could i use this for 5v (5mm) LED

Was going to use about maybe 10-15 led 20 max

 

Just need help with picking the LED for that.

I lit up an entire strip of LEDs using these:

And you'll see the recommended power supplies to go with them.

 

 

I've also tested these: https://www.amazon.com/gp/product/B01FJUMP6M/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

 

Plugged it into these USB hubs: https://www.amazon.com/gp/product/B00HL7Z46K/ref=oh_aui_search_detailpage?ie=UTF8&psc=1

Will that power adapter and power supply cable work with a Terminal Block that is connected to say 15 small 5mm led?

[hansangb]

Hmm, the adapter and power supply (first link) would be used in lieu of a terminal block. If you use a terminal block you cited, it doesn't use the 5.5mm x 2.1mm adapter plug. You have to wire up the AC on your own.

 

Is that what you were asking?

if i build using terminal blocks i would have to use the below psu correct?

Also it says is a 5V psu does that mean any LED would work without resister if its rated at 5v

Yes if you get bare led's they would need the proper resistor to limit the current to the led. That power supply has 20amp rating. From what I read most led's deal in milliamps. That's why i was asking about which led you were using. There would be a data sheet for it from the manufactorer that probably say min/max voltage and amp or watts. Which there is a math formula that can be done to figure out the resistor to place before the led. There are also LED's on a strip on the reels that have resistors attached to them already. So I am also no electronic expert but learning myself. If you look at the this amazon led https://www.amazon.com/Lemonbest-Flexible-3528smd-120leds-Waterproof/dp/B015R3TTP6/ref=pd_sim_60_1?_encoding=UTF8&pd_rd_i=B015R3TTP6&pd_rd_r=ZKSANZF4DNC6R1WNTYED&pd_rd_w=L9IC8&pd_rd_wg=YRGKv&psc=1&refRID=ZKSANZF4DNC6R1WNTYED the second picture down shows resistors on the strip. You might want to also post this question over the input/output section it might get more mileage over there just to confirm my answer.

Chewy,

 

Can you be more explicit in what you are trying to accomplish? Do you want to wire up LEDs so they light up when a switch is thrown, as described on the BU0836X product page?

 

If that is the case, you should be able to use the 5V supplied by the BU0836X board. You will need to look at the data sheet for the LEDs you are interested in and find the maximum current and the voltage drop in order to calculate the resistor required as Brewnix said. Subtract the voltage drop of the LED from 5V and then divide by the maximum current for the LED. That will give you the minimum resistance you need to prevent damage tot he LED. A larger resistor will result in a dimmer light.

You need to manage the total current you are pulling from the BU0836X. To be safe, multiply the number of LEDs by the current rating for the LEDs. This needs to be less than the maximum rating of the BU0836X, otherwise you may damage the BU0836X or your computer.

 

Hooking up an external supply is more complicated because you don't want to expose the BU0836X to a seperate 5V supply. This could cause weird currents to flow which may damage the BU0836X. A simple solution might be to use double pole switches, connecting the BU0836X input to one pole and the 5V supply, LED, and current limiting resistor to the other side.
