I am trying to select a relay for a delayed HT switch (which will also discharge the HT when off). Most relays I can find have contacts rated at 250VAC which translates into a peak of about 350V. However, data is scarce on what dc voltage these relays can switch. So far I have found only one that gives a dc current versus voltage curve and that stops at
210V dc (and 200mA) and I really want to be able to switch up to 350V at up to 200mA. The rest just give a dc voltage at max current value.So, I am guessing that this problem has been faced before and there are relays that are known to work fine in this application. Any recommendations?
By the way I prefer a 5V coil.
Cheers
