PULS DPA247.141 INTRODUCTION
The DPA154 is a very compact DC/DC Converter designed for field bus applications in which power and data share the same twisted pair. The unit supplies power, decouples data from the DC/DC Converter, and makes the two cables symmetrical for the shield terminal. The decoupling allows the use of unshielded cables. The PELV output circuit has electronic protection against overload and short circuits.
