PROJECT DESCRIPTION
The main concept of this project is to disconnect the main power supply automatically when no current is drawn by the load through an arrangement of transistor and relay circuit. The current drawn by the load can be varied from 3.5 to 8.7A by using the potentiometer setting.
PROJECT HIGHLIGHTS
Easy to use, Self-explanatory kit.
All-inclusive solution kit.
Extensive audio-visuals available.
Non-Microcontroller Project.
Branding-free material.
Save Energy by Self Switching PSU.
Call/mail for Tech Support from 10 am - 7 pm.
Can be Customized for Arduino, Raspberry Pi, PIC

Q & A
Q:  What is self-switching power supply unit (PSU)?
A:  When load is present it automatically switches on the supply otherwise it goes off.
Q:  What is the load used?
A:  12V, 6W incandescent lamp is used
Q:  What is the formula for calculating smoothing capacitor value?
A:  There is some approximated formula .Peak to peak ripple voltage = Load current in amps / (2*line frequency in hertz *capacitance in farads). But as rule of thumb for 1 A current 1000uF is best. Thus it is load dependent.

we referred this website,while searching the projects related to DC motors.
Because we studied the website and whatever the information we need,that’s applicable here itself,we liked video explanation a lot.
I and my friends purchase it through online.
