The
MiniLine-2
series
requirements in the range from 15W to 120W. These
units in their rugged plastic housing and large screw
terminals are highly efficient, very compact, easy to
install and are extremely reliable. Besides the standard
24V power supplies, many other output voltages are
also available as well as units rated down to -40°C.
More DIN-Rail power supplies in rugged plastic housings
can be found in the MiniLine family which is equipped
with quick-connect spring-clamp terminals. These units
come in power ranges from 25W to 100W and a variety
of output voltages.
The ML120 units are highly immune against electrical
disturbances on the mains and provides reliable output
power. This offers superior protection for equipment
which is connected to the public mains network or is
exposed to a critical industrial environment.
Besides the cost optimized ML120.244, two additional
units
are
available
in
ML120.CLASS2 fulfills the NEC Class 2 requirements and
the ML120.241 is the standard product with an auto-
select 100-120/220-240V input.
The supplementary MiniLine-2 redundancy module
MLY10.241 allows building of redundant systems or
protecting against back-feeding voltages.
