It probably has a TRIAC in it, and not an SCR.  The SCR would only
work on half of the AC cycle, so there would need to be two devices.

With a TRIAC it will only work with an AC load.  So if indeed this
device uses a TRIAC and does not use a mechanical relay, it's
unsuitable for a DC load.  Once the DC load turns on, it would never
turn off unless the load was otherwise disconnected.
