SITOP power
AS interface power supplies
Single-phase AS interface power supplies,
stabilized
■ Overview The IP65 version The IP20 version
■ Application
The AS interface power supply
unit with IP65 degree of
protection for any mounting
position is particularly suitable
for use in extremely harsh
environments. Thanks to the
24 V DC input voltage it is
ideally suitable for use together
with a proven SITOP
power 24 V standard power
supply unit.
This AS interface power supply
unit with its wide-range
input of 93 to 264 V AC and
110 to 350 V DC can be
universally used in all typical
power supply networks.
With limitation of the input
current harmonics acc. to
EN 61000-3-2; with SIMATIC
S7-300 design.
