1. I think you have some missing data, the input cannot be 12VDC or 28VDC... I'm guessing you have the input right, but missed the word "output" before the 96VS or 28VDC, but that does not make sense either. Take a look again.

2. VA as an output is NEVER a rating that works at all combinations of output voltage and current. That's why they use VA instead, makes the numbers look better. Long explanation, but take my word for it. You need specs on max output current at max voltage.

3. You always lose about 3 volts minimum from input to output of booster. 23VDC should top out at about 20V to the rails.

Max output voltage 20 volts, max current 8 amps, 80 VA... with the proviso that conditions can limit the output.

Often Digitrax cannot output full amps at full volts.

Should be fine, just have a power supply at 23 volts or higher, up to 28volts DC input. It may be that they USED to rate the output at 96VA, but it's not true.


He should be fine up to 6 amps for sure, above that, many people have reported that it cannot achieve full rated output, so he may not get 8 amps.

Have him put an ampmeter on the input side and see how much current he is drawing.

George, I know what you are saying about VA, and I'm sure you are technically correct.

But I have seen time after time a VA rating on the output / DC side, and the pack would not put out the same VA at all voltage/current combinations. Buy a MRC 6200, and try to get it's VA rating at top voltage, you cannot.

I think manufacturers are abusing this rating.
