Most of IPD’s products that are sold open frame can also be purchased with an optional chassis or chassis cover combination. The use of the chassis and chassis cover does provide some additional benefits to the power supply. Use of the chassis provides additional mounting options, ties all four mounting corners of the power supply to a common metal chassis and provides isolation for the components on the bottom of the board. Using the chassis cover option gives you all the benefits of the chassis option as well as assistance in suppression of radiated emissions and adds a layer of protection that can help keep objects from coming into contact with the energized components in the power supply.
