Summary:
Breadboard compatible Variable Power Supply.

সকল Electronics Hobbyist গণ তাদের project build এর ক্ষেত্রে সব থেকে বড় যে সমস্যা feel করে থাকে, তা হলো power crisis । বিভিন্ন project এ প্রয়োজন হয় বিভিন্ন Voltage Level, যেমন: 3.3V, 5V, 9V আবার কখনো কখনো 12V । বাজারে কিছু সস্তা Variable AC to DC Adapter পাওয়া গেলেও তার output খুব একটা stable নয় । Adapter থেকে 5V সিলেক্ট করার পরও Multimeter দিয়ে পরীক্ষা করলে দেখা যায় output কখনো কখনো 6V এর কাছাকাছি বা তার চেয়ে বেশি ! এ ধরণের Adapter ব্যবহারে অধিকাংশ সময় সার্কিটে থাকা chip গুলো over-voltage এর কারণে burn হয়ে যায় ! ফলে কাঙ্খিত output পাওয়া যায় না ! অনেক সময় একই সার্কিট বারবার build করতে করতে বিরক্ত হয়ে beginner level এর project builder গণ project তৈরীতে হতাশ হয়ে, কাজ করার আগ্রহ হারিয়ে ফেলেন !


আসলে better choice হলো lab power supply ব্যবহার করা । কিন্তু এই ধরণের lab power supply এর মূল্য ১০,০০০/= বা তার চেয়ে অনেক বেশি হয়ে থাকে । তাই beginner level এর electronics hobbyist দের কাজের জন্য এটি একটি বড় অন্তরায় হয়ে দাঁড়ায় ।


এসকল দিক বিবেচনায় আমরা beginner level এর electronics hobbyist দের কাজের সুবিধার জন্য তৈরী করেছি Breadboard Variable Power Supply । যা fully stable output দিতে সক্ষম ।


Breadboard Variable Power Supply বোর্ডটি Breadboard বা Project Board উপর সরাসরি সেট করা যাবে এমন ভাবেই design করা হয়েছে । তাই অতিরুক্ত ভাবে তার টানাটানির ঝামেলা থাকছে না একদমই । এছাড়াও on-board ডিসপ্লেতে আপনি output voltage দেখতে পারবেন ।


তবে হ্যা Breadboard Variable Power Supply কোন standalone power supply নয় । আপনি সরাসরি এর ইনপুটে AC-220V ব্যবহার করতে পারবেন না । প্রয়োজন হবে একটি AC to DC Adapter এর । আপনি maximum যে voltage level পর্যন্ত output কে regulate করতে চাইছেন Breadboard Variable Power Supply এর ইনপুটে আপনাকে তার চেয়ে 3V বেশি (AC to DC Adapter এর মাধ্যমে) ইনপুট দিতে হবে । 


 

 

N.B. No Transformer / Adapter is included with this package. 

  • Input Voltage:7V to 25V

  • Variable Output Voltage: 1.3V to 23V 

  • Variable Output Current: 500mA (+Vout Pin)

  • Constant Output Current: 800mA (+5V Pin) 

  • Output Current: 2A (Vin Pin)

Should I just use any adapter within the input voltage range?

By using "DC-DC boost converter" with "Breadboard Variable Power Supply", it is possible to increase the output voltage, thus decrease the output current.

anon
FAHIM_REAZA | Apr 21,2016 at 12:19 PM
You can use 8V (minimum) to 40V (maximum) both AC and DC as an input. You have to insure that, the voltage level does not exceed 40V, we recommend to use 33V maximum input.

whats its output ? if i give DC input then it will give DC or it converts AC to DC ?
anon
FAHIM_REAZA | Apr 24,2016 at 06:24 PM
It is not a factor that the input is either AC or DC; the output of "Breadboard Variable Power Supply" is always DC.

FAHIM_REAZA | Jun 21,2016 at 09:13 AM
Dear customer, at this time we have no such " 35V AC to DC Adapter" in our stock. You can search this product in local electronics market. Or you can use a such voltage rating step-down-transformer.
We have already made a conversation with our sourcing department, they will try to available this product soon in TechShopBD stock.
Thanks for with us.

Kriton091 | Sep 14,2016 at 05:32 PM
For people who is interested about this -

the O/P voltage depends on I/P voltage, so it is better to use a step down transformar with a custom made rectifier circuit that can provide near 24 Volts. The Higher the i/p voltage(obviously not more than 30) , the higher the o/p voltage.

My review - ★★★★★

You can use a minimum range of 8V and maximum of 40V as a input.
(recommended voltage is upto 35V). At 40V it will become very hot.

ইনপুট ভোল্টেজ সবসময়ই 7V to 25V এর মধ্যেই রাখতে হবে। নব ঘুরিয়ে ঘুরিয়ে আউটপুট অ্যাডজাস্ট করতে হবে।

We've investigated your case. If you've damaged the 14 pin DIL IC or the 7 segment display, we cannot provide you service warranty as we don't have those components available on our website. Please check the last line of point 1 of our warranty policy: https://www.techshopbd.com/about-us/support#warranty_replacement

A multi turn variable register along with the main variable register would make it easy to use in my opinion.

Also a connector header for the input voltage would have allowed us to daisy chain more then one unit of this PSU in the same project.

বোর্ডে থাকা IC টি কি তা না জেনেই এই প্রোডাক্টটি সম্পূর্ণরূপে ব্যবহার করা সম্ভব। সুতরাং আমরা IC মডেল / নাম্বার মুছে দিলে তাতে ব্যবহারকারীর কোন সমস্যাই হবে না। আমাদের প্রোডাক্ট কিনে কোন অসাধু ব্যবসায়ী যেন নিম্নমানের কপি/ ক্লোন তৈরি করতে না পারে তার জন্যই আমরা IC মডেল নাম্বার মুছে দেই।

I recently bought the product from you. The link to the blog you provided states that the voltage can be adjusted to 0.1V.But I cannot lower the voltage than 1.4 volts.That is the minimum output I am getting.Is there any way to lower it or is this the minimum voltage?
