The context of the problem is that I am trying to switch a ~200 VDC Meanwell Constant Current Supply @ 1.4A, to selectively power on a number of COB LEDs connected in series. My initial approach was to switch the power using a 30 VDC 10A optocoupler relay module.
I understand that this will certainly cause arcing during switching if the line is hot. However, I can cut off the mains input to the power supply right before the switch, and prevent any arcing since the relay would switch on a cold line. I'm sure that would work for mechanical switches, but is my understanding correct when we are talking about optoisolators?
I know this would be a risky way of implementing this, and I'd certainly go with a properly rated relay module for 200+ VDC, but being a newbie in this field I'm not well equipped to research for the most cost effective option here. If there's anyone here who can provide a recommendation for a SPDT relay at these ratings I'd really appreciate it. Thanks in advance!
