    Does anyone know of a Solid State Relay that has a 125VDC coil and a
    125VDC/3A output?

    1. Solid State Relays have no coil. They have a gate generally
    activated at logic levels.

    2. Relays do not have inputs or outputs, they are bidirectional and
    are merely a pass thru device.

    3. A device that is activated by and passes thru the same
    voltage/current, is generally called a fuse.
  3. If all you need is a garden-variety ssr, look at Crydom's stuff.
    Newark sells a lot of it. I know they have some units with 120vac
    trigger voltages, don't know about DC at that level. Most of the DC
    ones I've seen are 3-32v. I don't understand the current-limit part.
    Regular ssr's usually current-limit by failing. :) If you want
    variable chopper, look at SSAC stuff.
