Soft Start Advice

[GTJim]

I need a bit of advice as I’m getting slightly confused.
As you can see from the sketch below I want to include a basic soft start circuit into my control panel, but I have the main toroidal transformer, a 24 volt power supply and a 5 volt power supply.

If I ignore the 24v and 5v power supplies for now, I calculated the resistor required as HS50 33R. From the following:

I = VA / V
I = 750 / 230 = 3.26 amps
With a limit of 200% of the power current = 6.52 amps

R = V / I
R = 230 / 6.52 = 35.28 ohms

As I need both the 24 and 12 volt supplies, my questions are:

• Should I connect them up as shown, after the soft start or after the safety relay?
• Do I need to include the additional power supplies in the calc for a suitable resistor, and if so how?
• The HS50 refers to watts, I have only used this as it has been suggested in an article I read. Is this correct?
• I am hoping to find a suitable relay with a timer, can anyone point me in the right direction?

Regards,
Jim
