For sale is a NEW CKE BHD210 BHD211 High Current High Voltage SCR Rectifier Assembly. It was never used for anything. I do not really know what it does. It has four SCR hockey pucks inside. Each assembly has one big bottom heatsink, two separate top heatsinks, and one hockey puck between each smaller heatsink and one big heatsink. I am only guessing that it is a SCR rectifier. But it could be a high current room heater or a blow dryer. The semiconductor hockey pucks are ST230C12C0: http://www.mouser.com/ProductDetail/Vishay-Semiconductors/VS-ST230C12C0/ 410a 1.2 kV Please note that you are getting TWO fan cooled assemblies screwed down to ONE piece of ugly wood chip board. What you see is EXACTLY what you get -- and you do NOT get anything that you do not see (and no cart or beer).
