Solid state relay (SSR) for AC powered heatbed.
If you have an high power AC heatbed you need a SSR to use it with you RAMPS or similar.
Primary power: 12 VDC or 24 VDC
Secondary power: 230 VAC up to 2A (8A with additional cooling)
Please tell me if you need other attachment brackets.
Thanks to "Hardwarekiller" from RepRapForum for the idea with that Sharp part.
