This invention is directed towards a patient single surface system, PS3, which is a next generation system solution for patient accommodation, diagnosis, treatment, transfer and transport. The immersed-filtration array is composed of a plurality of individual filtration modules. The pass element is configured to be coupled to a power supply and a load, and is configured to electrically couple the power supply with the load during ON-state and electrically decouple the power supply from the load during OFF-state.
