This is just a very basic panel for an AC plug and DC jack. The AC plug is from an old power supply but i imagine is very common. The DC Jack is a 2.5mm jack from radioshack.I use the AC Plug to power my SSR/Silicone Bed while the DC jack powers my electronics. Print.Insert AC and DC Jacks into holes.Secure with nuts.If you have an SSR just mount it opposite this plate directly onto the extrusions. I used kludgineers M4 T-slot drop in's.
