Somebody was talking about 48V warts. Some standards only allow 24V (for wet environments), and 32V for certain parts of the world
48V wall-warts/bricks are typically used in midspan PoE
injectors (and as standalone power supplies for PDs
without PSEs). As such, almost always in dry locations.
Can those "certain parts of the world" use PoE products
with nominal 48VDC delivered over the twisted pairs?
Is the limit on the "packaging" or on the potential?
