KNX PS640-IP Router / Power Supply System
 |  |  |
The Power Supply System KNX PS640-IP combines the central functions of a KNX bus line: Power supply with throttle, IP router and IP interface:
The Power Supply Unit of the KNX PS640-IP delivers 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, 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.
The IP router of the KNX PS640-IP allows for forwarding of telegrams between different lines via a rapid LAN (IP) backbone. The KNX PS640-IP therfore also takes on the function of a line coupler.
In parallel, the KNX PS640-IP can be used as interface for accessing the bus access via IP. Like this, the KNX system can be configuered and supervised from any PC in the LAN (Tunnelling).
