KNX power supplies generate and
monitor the KNX system voltage (SELV).
The bus line is decoupled from the power
supply by an integrated choke.
The voltage output is short-circuit and
overload protected.
The two-color LED indicates device
output status.
This device has an additional 30 V DC
short-circuit and overload protected
voltage output that can be used to
power an additional bus line (in
combination with a separate choke).

Important
If the device overheats due to extended overload (> 100 °C in housing) it switches off automatically.
The LED is off. The device can be switched on again only after it has been disconnected from the mains
for 60 seconds and has cooled to operational temperature internally.
Eliminate the cause of the overload before switching back on.
When commissioning the device, ensure that the rated current is not continuously exceeded.
The voltage output without choke ( I2) is not electrically isolated from the KNX voltage output (I1). It may
only be used to power an additional bus line in combination with a separate choke. It may not,
for example, be used to power IP devices (see SELV guidelines).
Devices are designed for continuous operation. They are not approved for frequent switching on and off.

Accessibility to the device for the purpose of operation, testing, visual inspection, maintenance and repair
must be provided compliant to VDE 0100-520.
Mounting
Mounting and commissioning may only be carried out by electrical specialists. The appropriate standards,
directives, regulations and specifications should be observed when planning and setting up electrical
installations.
Protect the device from moisture, dirt and damage during transport, storage and operation.
Only operate the device within the specified technical data!
The device should only be operated in an enclosed housing (distribution board)!
Cleaning
If devices become dirty, they can be cleaned using a dry cloth. Should a dry cloth not remove the dirt, they
can be cleaned using a slightly moistened cloth and soap solution. Corrosive agents or solutions should
never be used.
Maintenance
The device is maintenance-free. No repairs should be carried out by unauthorized personnel if damage
occurs, e.g. during transport and/or storage. The warranty expires if the device is opened.
Control4®KNX
For Control4®KNX devices, it is possible to adopt the parameter settings and group addresses from earlier
versions of the application program from ETS v.5.6.6 (or higher).
•Import the current VD file into ETS and add a product to the project, using the current application
program.
•After you have parameterized a device, you can transfer the settings to a second device. For this
purpose, the devices must already be available in the ETS project.
•Right click on the product and select Conversion in the context menu for this purpose.
•Then follow the instructions in the dialog window.
•Finally, you must replace the physical address and delete the old device.

Control4® KNX Power Supply Standard, 640 mA, MDRC, SKU: C4-KNX-PS640MA (KNXPROD File
Name: SV/S 30.640.3.41. Download: https://ctrl4.co/knx-ps640ma) devices have a 30 V DC voltage output
without choke. This can be used in combination with an additional choke to power a main or area line. To
do this, the devices must be installed in accordance with the connection schematic below.
Please note
The voltage output without choke may not be used for other purposes (e.g. for connecting sensors to a
binary input) because in the event of an error on the voltage output (e.g. a short-circuit) the power
supply and therefore the whole KNX line connected to it will fail!
The voltage output without choke ( I2) is not electrically isolated from the KNX voltage output (I1). It may
only be used to power an additional bus line in combination with a separate choke. It may not, for
example, be used to power IP devices (see SELV guidelines).
Control4®KNX
During a reset the bus line is disconnected from the output voltage and shorted. This restarts devices
connected to this bus line. The red Reset LED lights up for the duration of the reset. The LED goes off
when the reset is complete. A reset takes around 20 seconds.
If the line is to be disconnected from the voltage for an extended period, pull off the bus connection
terminals from the KNX power supply.
Reset via bus connection terminal
Pull off the device's bus connection terminal for approx. 20 seconds.

Indicators for normal operation, short-circuit and overload
green/
red
Description
Recommendation
ON
green
Device operating normally.
ON
red
Output overloaded.
Rectify overload or reduce number of bus
devices until there is no longer an overload
and only the green UNOK LED is lit.
Flashing
red
Current limiting active.
Reduce number of bus devices until only the
green UNOK LED is lit.
Communication error indicators
Description
Recommendation
ON
The LED comes ON for 1 second if there is a
transmission error or if a telegram fails or is
incomplete (e.g. “BUSY”, “NAK” (receipt not
correct)).
If the LED lights up frequently or flashes, check
the topology or connections. For a more
accurate diagnosis, use ETS Bus Monitor
logging.
