Why is the 140CPS12420 not compatible with the 140CPS12400 when used in a redundant configuration ?

The two power supplies cannot share the output current normally due to the difference of their internal parameters. The internal current APS_SENSORS do not have the same gains. If the two power supplies operate in parallel, this will cause one power supply to not operate normally with its PWR OK LED off.
