2.Redundant function
(1) UHP-350R is built-in redundant function and can be connected 2 units in parallel .
(2) When in parallel operation the maximum load should not be greater than the rated power of any PSU.

In order to meet the“Derating Curve”and the “Static Characteristics” ,UHP-350 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-350 series must be firmly mounted at the center of the aluminum plate.
