A50 additional power supply PSR for optional modules

Z = K90
Spare part order no.: 6SE7090-0XX85-0KA0
The additional power supply A50 is connected to the module A23 by means of a 2-pole cable and inserted
on the left in slot 1. The module is secured on the electronics box by means of the screws of the extraction
aid (earth-reference potential connection: see Chapter 3.2.3).
The maximum total power that can be extracted is 19 W (taking into account the
maximum consumption of the common rectifier and common 2 A fuse for the DC 24 V
power supply on the module A23).
