Unboxing EC-6647 300 Watt (20A) DC-DC Buck Converter Step down Module - by Sartaj Singh Virdi

Here is the unboxing of 300 Watt (20 Amperes) DC-DC Step-down with adjustable Constant Current. The voltage can be adjusted from 1.2 Volts to 36 Volts. This unmatched module (EC-6647) provides a wide range of current output up to 20 Amperes. It can easily manage to run high power projects continuously.
The module EC-6647 has onboard multi-turn trimpots that I am changing with external multi-turn potentiometer to use this buck converter as a regulated power supply. These multi-turn potentionmeter are for very high accuracy voltage and current regulation to provide good stability.
The voltage and the current are adjustable and it gives very easy to use at multiple projects:
Examples of projects that could be powered by this buck converter:
- Battery Charger
- LED Driver Power Supply
- Vehicle Power Supply
- Regulated Power Supply (if you use external potentiometers)
- Amplifiers
- Arduino Projects
- Robots
Specifications:
- Product Code: EC-6647
- High Power DC-DC Step Down Module
- Input Voltage: 6 Volt - 40 Volt DC
- Output Voltage: 1.25 Volt - 36 Volt DC
- Efficiency: 97%
- Current: 0-20 Ampere
- Maximum Power: 300 Watt
It has a wide range of applications at a very reasonable cost of Rs.585/- in India.

Yes you can charge any battery using this Buck Converter! I have charged 12V 7AH battery using this Buck Converter - it is amazing!!! Thank you.

Sir total price or what is the sapping market name

[@whitehacker6171]

How to measure how much current it is giving outout???

[@TMSVirdi]

At the output of the DC-DC buck converter you can use the AMP/Volt Meter as shown in this circuit diagram. If you find it little tedious, then let me know I will show you a simpler example. Example: www.technotaj.com/2021/07/06/best-variable-power-supply-circuit/

[@whitehacker6171]

@@TMSVirdi then what is the use of the current control of the buck converter??

[@TMSVirdi]

@@whitehacker6171 The use of Current Controller (Trimpot) on the buck converter is to adjust the current for the device that you want to use with it. example, an amplifier, radio or Arduino board etc... However, I have replaced these (Current limiting Trimpot) and (Voltage limiting Trimpot) with equivalent value Multi-Turn potentiometers as I want to use this buck converter as a regulated power supply - so that I can use it externally with hands and not through screwdrivers. 🤘This gives me flexibility to change the current value and voltage even when the buck converter is fixed in a container box.

@@TMSVirdi i watched many videos, i saw in all of them that they can't control the current output using the cc screw.. Can u suggest me a video where they show it can be controlled??
