منبع تغذیه جریان ثابت یا Constant Current (به اختصار CC) به منبع تغذیه ای گفته می شود که با تغییر بار جریان ثابتی را ایجاد نماید . ساخت چنین منبع تغذیه ای محدودیت هایی را ایجاد می نماید . در بسیاری از درایورها و منابع تغذیه ای که دارای کنترل جریان می باشند یک بازه ی ولتاژی نیز درج شده است . این بدان معنا می باشد که این منبع تغذیه یا درایور در بازه ی ذکر شده می تواند جریان ثابتی را ایجاد کند . 

constant current

به عنوان مثال برروی یک درایور LED  عدد 3V - 12 V  ~  320 mA   درج شده است . این بدان معنا می باشد که این درایور می تواند در خروجی ولتاژ 3 تا 12 ولت را با جریان 320 میلی آمپر را ایجاد کند . ماکزیمم ولتاژ خروجی این درایور 12 ولت می باشد ولی مینیمم ولتاژ 3 ولت می باشد . در ولتاژ های کمتر از این ولتاژ درایور دیگر بصورت منبع جریان عمل نخواهد کرد . در بسیاری از مواقع این رنج دامنه ی ولتاژی کم می شود یا به اصطلاح منبع درایور خاص محصوب می شود که برای یک بار مشخص کاربرد دارد .

My wife and i have been so thrilled that John could do his studies
out of the ideas he grabbed using your web pages.
It's not at all simplistic to just be offering hints which most people might have been trying to sell.
So we remember we've got the website owner
to give thanks to for this. The main illustrations you made, the easy blog menu, the relationships you give support
to foster - it is many wonderful, and it's facilitating our son and
our family imagine that this theme is enjoyable, and that is very fundamental.

Thanks for all!

Undeniably consider that that you said. Your favorite reason seemed to be at the internet
the simplest factor to bear in mind of. I say to you, I certainly get annoyed even as
people consider concerns that they just don't know about.

You managed to hit the nail upon the top as neatly as defined out the whole thing without having side-effects , people could
take a signal. Will likely be back to get more.
Thank you!

Yesterday, while I was at work, my sister stole my iphone and tested to see if
it can survive a 25 foot drop, just so she can be a
youtube sensation. My iPad is now destroyed and she has 83 views.
I know this is totally off topic but I had to share it with someone!
