      An improved power system would be one that could provide all the advantages of a DC-DPS over the centralized power supply distribution, but at a lower cost, smaller board space, and fewer components. Low voltage 24VAC DPS power systems are used today at 60Hz for security and survival systems, outdoor lighting, and control systems.
