Switching Power Supplies: 480 VAC to 24 VDC
While we are discussing control power supplies of varying voltages, I have a question. Has anyone had any bad experiences with using a 3-phase 480 volt-to-24 volts DC power supply? I am looking at a Sola Hevi-Duty unit (switching type direct 3-phase-to-DC conversion) for a project. The reason is that this project is mounted on a couple of skids (portable), there is very limited space, and I must give up something. I am trying for only two voltages, 480/277 to run the motors and lighting, and 24 vdc for everything else (controls, valve operators, instruments), and no transformers at all.
