## Summary description

Gira KNX power supply REG 212200 provides a 320 mA output with integrated choke for KNX bus systems. Designed to feed KNX devices and sensors, it ensures stable bus voltage and protects against interference. Suitable for residential and commercial KNX installations where a dedicated 320 mA supply and line damping are required.

## Long description

The Gira KNX power supply REG 212200 delivers a stabilized 320 mA output with an integrated choke designed for KNX bus systems. It supplies KNX devices and sensors with the required bus voltage while damping disturbances on the bus line. The device is intended for mounting in standard electrical distribution boards and is suited for both residential and commercial KNX installations where a dedicated 320 mA source and line filtering are needed.
Advantages
The power supply provides a constant 320 mA current to KNX installations and includes an integrated choke to reduce electromagnetic interference and voltage dips on the bus line. Its compact form factor enables mounting in common DIN-rail distribution cabinets and simplifies wiring by offering a reliable centralized power source for multiple KNX devices. The unit is designed to meet the electrical requirements of KNX components, ensuring stable operation and improved bus communication.
Suitable for
 Supplying KNX actuators, sensors and panels in small to medium residential installations
 Providing a dedicated 320 mA KNX power feed in commercial or office projects
 Installation in distribution boards with DIN-rail mounting for organized wiring
 Environments where line damping is required to reduce interference on the KNX bus
When it may not be suitable
This power supply is not intended for standalone use with non-KNX devices or for systems that require more than 320 mA of bus current. If the KNX installation demands higher total bus current or multiple independent power domains, a higher-capacity or additional KNX power supply should be considered. It is also not suitable where different system voltages or specialized power management functions are required.
Key specifications
 Output current: 320 mA (stabilized)
 Integrated choke for line damping and interference suppression
 Mounting: DIN-rail compatible for electrical distribution boards
 Intended application: KNX bus power supply for devices and sensors
 Suitable for residential and commercial KNX installations
How to use
Install the power supply on a DIN-rail inside the distribution board according to local electrical regulations and wiring standards. Connect the mains input and the KNX bus output following the manufacturer's wiring diagram and ensure correct polarity and secure terminations. After powering the unit, verify that the KNX bus voltage is within expected ranges and monitor communication stability. If additional bus segments or longer cable runs are used, review voltage drop and consider segmentation or additional supplies as needed.
What to consider before purchase
 Verify total KNX bus current requirements to ensure 320 mA is sufficient for all connected devices
 Check available space in the distribution board for DIN-rail mounting
 Confirm compatibility with the KNX topology and whether line damping is desirable
 Ensure installation will comply with local electrical codes and grounding requirements
Usage recommendations
Use this power supply as the main 320 mA feed for a single KNX line or as part of a segmented KNX installation. Combine with proper bus topology planning, correct cable types, and secure terminations to maintain stable KNX communication and minimize interference.
