I have an 'oft postponed low voltage bench supply project. I'd start with a 24VDC deep-cycle battery, float charged from auto-controlled solar, pedal-power, and AC sources.
The front panel would be a series of PowerPole connectors and each connector would be matched to a switch that steps down from 24VDC to the common voltages. One unresoloved detail was to use resistors, diodes, regulators, etc. Minimal loss and minimal RFI are design imperatives. Also, unresolved are the maximum total and individual current capacities. Possible voltages are 3. 4.5, 5, 6.3, 7.2, 8.4, 9, 12, 14.5, 16, 19, 22, 24, etc. WDYT? -- Thanks! & 73, doc, KD4E > Is there a reason we can't sart some sort of campaign to eliminate "wall > warts".
