48-220V DC / 24 V DC/0.375 A
■
Overview
The optimum power supply for automation solutions in the lower
performance range; with wide-range input for
48-220 V DC
;
thanks to their compact and slim design, they are particularly
suitable for solutions where space is limited and in conjunction
with low-voltage switchgear.
