AK-230
DIY 30VDC Regulated Power Supply
(0-30VDC/1A)
Let us Begin Soldering!
We Require Solder Iron, Flux and
Solder Wire.
This Manual does not talk more
about soldering, you need to
know basics of how to use solder.
Parts Included:
•
Diodes: 1N4007(5)
•
Transistors: 2N5551(1)
•
Capacitors: 470uf/50V (1),
10uf/25V (1), 2200uf/50V (1),0.1uf
(CD104-2).
•
Resistors: 5.1K Ohm (1), 220 Ohm
(1)
•
Switch (1), 5K Mini Potentiometer
(1), 5mm 2 pin Terminal block (1).
•
Speaker Terminal (1), Heat Sink for
TO220,5mm Red LED (1).
•
3mm Screw (1)
•
One PCB Board.
#The PCB Side with names and symbols
is "TOP" and opposite side is
"BOTTOM". We need to place the
components on the TOP and solder to
the BOTTOM.
Step 1: Start with Diodes. Solder all
1N4007 diodes at their respective places
on the PCB. The diode is labelled with
its name on PCB top.
* White mark on the diode indicates the
N side (Cathode).
The polarity of the Diode is important.
The White band on the diode should go
to the same direction of white band on
the PCB TOP.
