Introduction: Surge Protector
This is a surge protector
Step 1: Surge Protector
Hi, today i will show how to make a surge protector.It will protect your electronics items in surge or spike.Surge and spike means over voltage,over current and high frequency.It will protect from eddycurrent.High voltage in high frequency is known as eddycurrent.
Step 2:
When the input power ON the green led turn On.When we press the push on switch the output power will on.The red led indicate output power on.
Step 3:
I added a 1 ampere fuse and fuse carrier you can use 2a or 3a fuse for higher load
Step 4:
The output voltage is stable
Step 5:
I added a led indicator for showing fuse blown.If we shorted the output the fuse surely blow.
Step 6:
Take a look at the inside.?
Step 7:
This is the circuit diagram
Step 8:
compounds-
1)12v relay five pin
2)12-0-12 500ma transformer
3)In4007 diode
4)1000uf/25v capacitor
5)Bt 169 scr
6)1k resistor (2)
7)470 ohms resistor
8)2.2k resistor
9)green (1) red (2) led
10)Mov 250v
11)push on switch
12) 3a fuse and fuse carrier
13)3pin socket
14)3pin code wire
15)plastic container
Step 9:
Thanks i hope you like this.?
