Greetings.
I am rebuilding the control system on a DSG lathe. I changed the original 15HP motor which had a 2-step time-delay start system to a 10HP standard motor so this allows considerable simplification of the control panel.
The original control panel used 24V AC control power but I am integrating some solid state components and I would like to use 24V DC for control throughout the system. However, some of the control panel functions would be simpler to implement using the original contactors and I would like to re-use some of these so I will have a mixed system of SSRs and mechanical contactors.
What do you think of simply switching the power supplies from AC to DC? I plan on adding anti-surge diodes to the coils but are there any other problems with this idea?
Thanks, Brian
