Hi,
I am ideally looking for a SMPSU that is able to be adjusted over the o/p range 10V to 24V at about 80A, with an i/p of 240V, 50Hz.

The adjustable ones I've found so far have a much more limited o/p range, and I would have to buy at least 2 to cover this o/p range, or are somewhat expensive.

My absolute minimum requirement is 11.1V and 21.5V at 80A, and 2 x 12V units with about a +/-10% adjustment could do this - IF they could be connected in series for the 21.5V o/p, or used singly for the 11.1V spec.

Is there a special requirement of a supply to enable a series connection like this,
or would any SMPSU be capable.

With best regards, Paul.
Nothing so constant as change.
