The Power Supply Systems KNX PS640+ and KNX PS640+USB deliver a 29 V bus voltage for the KNX system and 24 V DC supply voltage for 24 V devices. The KNX PS640+USB has got an additional USB interface for easy bus access.

Special operating conditions such as short circuit, electrical surge, overcharge or excess temperature are recorded and may be read off on the display. The present power discharge is displayed as well. It is possible to reset the connected bus devices directly by means of the key pad. 

In addition all functions can be realised via the bus, too, e. g. the transfer of malfunction messages and operating data and a time/period reset. Malfunction messages are stored by the KNX PS640+(USB).
