SSR Relay / Dc to Dc.

Hi all.

I have this SSR relay and i am not sure if i could use it for Dc to Dc.

Note: This is the thing i want to control with Arduino: http://www.ebay.com/itm/Ultrasonic-Mist-Maker-Fogger-Humidifier-Water-Fountain-Pond-Fog-Machine-DC-24V-/351148904163?pt=UK_Home_HomeDecor_Miscellaneous&hash=item51c21b0ee3

Thanks in advance.

The specification for the SSR says

Output voltage:24-380VAC

The mist device itself runs on 24V DC but comes with a mains adaptor to provide the 24V so it seems possible that it could be turned on and off by the relay.

The SSR you linked controls AC only. You could use it to control the AC to DC power adapter for the fog machine (which requires 24 VDC).

Thank you guys.
