- Thorough research ... found that some switchmode power supplies have current limiting if overloaded ... so can just choose a power supply with max rating (according to specifications sheet) being the maximum charging rate required.
- Meanwell RSP series is perfection (constant current limiting, resistor controlled voltage, remote on/off, and seperate 5.0V power supply).
- Meanwell PSP series is still good (constant current limiting, but with less features)
- Meanwell SP series (cheaper, and without features) has "Fold back current limiting"
- !! NOTE !!! Other, cheaper supplies, have "hiccup" protection, meaning completely switches off, waits, and re-starts ... which would be complete and utter crap for charging.
- Lamda supplies also look good.
- Have sent email to Computronics, who import the Meanwell power supplies.
......NOTE
- Discovered on "Procon" site, that the "Manson" adjustable power supplies (same as my existing adjustable power supply) can be used in parallel for higher voltages. Also, the "top of the line" Manson power supply (9602) can be controlled externally by (eg) Pic microprocessors. Remote on/off. Remo
- Advantage #1: You get two additional very good power supplies, completely adjustable, and usable for other projects.
- Disadvantage #1: There are two power supplies, meaning double the things that can go wrong.
- Disadvantage #2: The supplies are not "current limited" in the way required, which means that a microprocessor is required to make them work ... which is another thing that can go wrong (with catastrophic consequences !!)
- Disadvantage #3: It can never be just "plug in" and so, cannot be used by the boys.
