The power supplies themselves are modern and highly efficient GaN power supplies, enabling a compact design of only 6 TE (modular dimensions).<\/p>\n<p>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. <a href=\"mailto:info@ab-smarthouse.com?subject=%5BOpenKNX%5D%20Bus%20Power%20Supply\">report<\/a>.<\/p>\n<p>The optional enclosure is printed as standard in an environmentally friendly &quot;PLA+&quot; material, largely composed of biological components (e.g., cornstarch). This material is dimensionally stable up to approximately 55\u00b0C. For high ambient temperatures inside the control cabinet, it can also be printed in &quot;PC FR&quot; plastic, which remains dimensionally stable up to approximately 110\u00b0C and is also flame-retardant according to UL 94-2023 V-0.<\/p>\n<p dir=\"auto\">If you have any questions or feedback about the project, please <a href=\"mailto:info@ab-smarthouse.com?subject=%5BOpenKNX%5D%20Bus%20Power%20Supply\">make contact<\/a>!<\/p>\n<p dir=\"auto\"><strong>Please note:<\/strong><br \/>\nTo upload the firmware of all OpenKNX compatible projects offered here in the shop, <a href=\"https:\/\/www.ab-smarthouse.com\/en\/product\/openknx-progger\/\">this programmer<\/a> needed.<\/p>\n<p dir=\"auto\"><strong dir=\"auto\">Delivery as a kit:<br \/>\n<\/strong>All OpenKNX-compatible projects offered in the shop are delivered as a kit and without software.
