Good afternoon guys and gals
I have been trying to create a 5A power supply for a specific application.
Am nearly there and have had much help from AAC people to get here.
I have a system currently (attached) that runs a relay and electronic dc motor speed controller up to 5A
It runs from a 60VA 240V to 12VAC electronic transformer.
Voltage at the output of the current system however is less than 10 and fluctuates 1 to 1.5V.
This is too low to run my motor controller which has a low voltage CO.
I'm also worried about damage from the fluctuations to my motor speed controller.
Initially I was getting 16V without the ZD and Transistor circuit (too much too much).
AnalogKid has suggested the use of a couple of 1N4004's in series to correct and an 18 ohm resistor (thanks for all your help AK). See dwg attached.
(if you're there AK a last bit of a look would be brilliant of you)
Q's - Have I too much Capacitance?
- Have I got the orientation of the 1N4004's right?
- Should I go to a 15V ZD?
- Will it stop the fluctuation
