Hi guys,
I'm brand new, so apologies for jumping straight into asking for help. I'll definitely contribute myself where I can with other forum members problems.
I'm trying to design a slow start circuit to stop a UPS from tripping from my devices inrush current when it starts up.
Unfortunately it needs to be on the mains supply side, because I'm using an off the shelf power supply (OEM -> AC-DC) to save costs, so I can't implement something after the transformer (lower voltages) like I could if I was designing my own PSU.
I know some people switch in resistors progressively on startup and that kind of thing utilising relays or similar on the high side. I also read somewhere of people also using NTC resistors on startup too.
Are there any other solutions I haven't found? Any suggestions from your side that you can think of?
