This is a kit for an OpenKNX-compatible 1280 mA bus voltage supply with diagnostics and optional redundant power supply.
The power supply provides a choked 30 V DC (red/grey connection) to the bus connection as well as an additional 30 V DC unchoked auxiliary voltage (yellow/grey connection).
The power supply operates on 230 V AC, with the option of installing a second power supply for redundant operation. The power supplies themselves are modern and highly efficient GaN power supplies, enabling a compact design of only 6 TE (modular dimensions).
We plan to offer a 9-60V DC power supply unit, which can be used as an alternative to one (or even both) of the 230V AC power supplies. A wide input voltage range of 9-60V was deliberately chosen to allow for the connection of both a small, local battery storage system (usually 12 or 24V) and a 48V PV battery storage system as a backup. This DC power supply unit is not yet available, but please let us know if you are interested. report.
The optional enclosure is printed as standard in an environmentally friendly "PLA+" material, largely composed of biological components (e.g., cornstarch). This material is dimensionally stable up to approximately 55°C. For high ambient temperatures inside the control cabinet, it can also be printed in "PC FR" plastic, which remains dimensionally stable up to approximately 110°C and is also flame-retardant according to UL 94-2023 V-0.

Please note:
To upload the firmware of all OpenKNX compatible projects offered here in the shop, this programmer needed.
Delivery as a kit:
All OpenKNX-compatible projects offered in the shop are delivered as a kit and without software. The user is free to use his own software or the OpenKNX-compatible software, which is available via the OpenKNX “Open Source” directories on GitHub (OAM Bus Power Supply) is available. In the latter case, this can be done with the OpenKNX Toolbox easiest.
Since the power supply operates on a 230V mains voltage input, please note again that this kit is not a finished and certified product. Therefore, use is at your own risk! The AC/DC power supply used here, however, is CE compliant. A corresponding declaration of conformity can be found [here/below/etc.]. here.
