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.

Company/Model	Output Voltage (V)	Output Power (W)	Output Current (A)	Special Features
ABB Entrelec CP Range	5 to 48	—	300 mA to 20 A	*Touchproof connection terminals; *most CP types accept 90 to 260 Vac, 47 to 440 Hz input with no adjustment; *supply with 105 to 260 Vdc is possible with nearly all CP types
