In order to meet the“Derating Curve”and the “Static Characteristics” ,UHP-500 series must be installed onto an aluminum plate(or the cabinet of the same size)
on the bottom.The size of the suggested aluminum plate is shown as below. And for optimizing thermal performance, the aluminum plate must have an even and
smooth surface (or coated with thermal grease), and UHP-500 series must be firmly mounted at the center of the aluminum plate.
