Description
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. Special
operating conditions such as short circuit, overvoltage, overload or excess tempe-
rature are recorded and may be read off on the display. The present power dischar-
ge is displayed as well. It is possible to reset the connected bus devices directly by
means of the key pad.
