I have a question about a system I have with a 115VAC source, and two 28 VDC power sources (A and B) The 28 VDC source (Source A) provides initial power to a diode on a bus bar.
The 115 VAC source powers a component that outputs 28 VDC to energize a relays to provide power to other components in the system. Through these relays, a second 28 VDC source (Source B) powers a different diode on the same bus bar with the diode that Source A powers.
This is the main potential issue with the system, the grounds for the diodes powered by the relays through the 115 VAC power source run back as a return to Source A. After the system is energized through the 115 VAC source, will turning off Source A pose a problem to the system as the grounds return back into it? Let me know if this anything needs clarification or if I posted in the wrong subforum. Thanks for your help
