Switching negative voltages
« on: April 03, 2018, 10:46:20 pm »
Hi,
I have a few of these ssr’s (https://www.mouser.co.uk/datasheet/2/205/Lcc110-444.pdf) in my supply but there’s one thing I don’t know about them... can these, or any SSR, switch negative dc voltages? For instance, given that the voltage rating of this particular SSR is 350v dc, does that mean it can also switch -350 dc? If this is not the case then any suggestion would be welcome.
Thanks in advance

Yes, those do both AC and DC, meaning negative and positive.

It's the LED which has only 1 polarity.
