200 VDC relays

200 VDC relays

200 VDC relays

(OP)
I was wondering if anyone knew if there were any "off the shelf" 200VDC (and pulsating DC) solid state relays that could be purchased which can handle up to 10 amps. I can only find AC SSRs in this range.
If not would there be a schematic available showing how to use something like an IRF640 MOSFET to act like a DC relay especially if it could use a separate low voltage applied to the gate (from an IC) to control up to 200VDC and pulsating DC.
Thanks.

RE: 200 VDC relays

Do a google search on "DC solid state switch", lots of resources. They are not necessarilly referred to as relays, that may have been your problem finding them.
