Right. Even the PSU2 transformer generates a small magnetic field but it is
much smaller that those of the old PSU1. So far we never detected any hum
noise even for modules mounted very close to the PSU2. In any case a safety
distance of at least 2-3 cm (i.e. about 1 inch) between transformer and
module should be kept. For standard frames that's no problem but for
suitcases some deeper modules (e.g. A-113, A-126) should not be or cannot be
mounted above the PSU2.
