Description
Introduction
The WEINZIERL KNX PowerSupply 365 is a compact 640 mA KNX bus power supply designed for DIN rail installation. With a width of only 4 modules, it provides the KNX line supply in a space-efficient format while integrating the bus choke directly into the device.

For installers and system integrators, the front-panel diagnostics are particularly useful during commissioning and service. Three multicolor LEDs indicate the operating condition of the device, including overload warning, exceeding temperature, telegram traffic and reset status. The unit also provides an auxiliary power output via a yellow/white connector.

Key Features
- 640 mA KNX bus power supply
- Integrated bus choke
- Auxiliary power output
- Three multicolor front LEDs for device condition indication
- LED signalling for overload warning, exceeding temperature, telegram traffic and reset status
- Two buttons for resetting the KNX line
- DIN rail mounted device
- Compact width of 4 modules / 72 mm
- Plug for external power supply 230 V AC
- Yellow/white connector for auxiliary power output
Benefits
This power supply is well suited to KNX panels where reliable line supply, clear local diagnostics and cabinet space matter. The integrated bus choke reduces the need for a separate choke device, helping keep the installation layout clean and compact.
The multicolor LED indication gives installers immediate visual feedback during commissioning and troubleshooting. Overload warning, temperature status, telegram traffic and reset status can be checked directly at the device without additional information being required from the product data supplied.
The two reset buttons provide a direct method to reset the KNX line from the front of the device, supporting practical service work inside the panel.
