Last month's “Analog Feedback” department discussed some of trends and technical issues shaping the development of DIN Rail power supplies. That article described some of the general specifications and features associated with these products. In this edition of “Analog Feedback,” we examine how these development trends are reflected in a sampling of recently developed models.
The table lists some of the key specifications and features for these models. Not included in this list are the various agency approvals.
