Additional advice to isolating transformer
®
The PeakTech 2235 is is developed and manufactured in protection class
I, so the primary side has a protective earth connection of the housing, but
without reference to the secondary side.
The secondary side of the isolating transformer is galvanically isolated from
the primary side and outputs the voltage without additional smoothing or
voltage conversion at the C-type outlet socket.
The principle of operation of an isolating transformer: Since the secondary-
side voltage has no relation to the earth's potential, no faulty current can
flow through the protective grounding or the primary-sides neutral
conductor. This reduces the risk of electric shock and therefore a danger to
the user is prevented.
