AC-DC Power Supply with IP Interface for KNX Installations

April 28, 2020 by Paul Shepard

JUNG has extended the concept of system devices and has brought two essential areas together. The new ac-dc power supply (320mA) with IP interface enables more efficient operation on several levels simultaneously.

Due to the combination of power supply and IP interface, the device combines two major systems into one component. With the ac-dc power supply with IP interface, professional installers can implement KNX installations more cost-effectively.

It creates a cost advantage, particularly in price-sensitive installations, as the installer can save on components. The new interface has an output of 320 mA to supply KNX nodes and couples the IP network to the KNX components. The new power supply is of course secure thanks to KNX Secure.


  • KNX Data Secure:
    • Components on the bus line are secure thanks to encryption with KNX Data Secure.
  • KNX IP Secure:
    • Devices located on the network line after the power supply with IP interface are also secure.
  • Power supply of KNX nodes:
    • Energy-efficient operation with a wide range input (110- to 230Vac) with high efficiency of 88%.

Application Examples


  • With the three structurally identical performance classes of 160mA to 640mA, extensions can be made at any time or devices can be replaced by those of the next higher performance class. With the 1,280mA version, it is even possible to support twice as many devices as previously – which saves costs.

Smart Hotel

  • The new power supply with IP interface is ideally suitable for self-contained units such as individual hotel rooms. In this way, all connected devices can be supplied with power cost-efficiently and while saving space. The integrated IP interface also links the installation to the IP network.


  • For the complex applications in a hospital, the different power supplies can be mixed: small for individual rooms, large for complete areas or floors. The integrated diagnosis function provides security by notifying about overloads or breakdowns in good time.

Single Family House

  • A complete family house can be built with just one KNX line with more than 100 devices having to be supplied. This is possible with the new 1,280mA power supply. The advantage for owners: it saves costs as no other system devices are required.
