Description
Introduction
The theben LUNA 134 KNX (SKU 1349200) is a high-performance 10-channel light level controller engineered for precise, brightness-dependent automation in KNX building control systems. Designed for top-hat DIN rail mounting (3 modules wide), this system includes an external light sensor in the delivery box, allowing seamless measurement and regulation of ambient light conditions across commercial and residential infrastructure. This device is part of our KNX System Components products range.

Operating on an input supply of 110 – 240 V AC at 50 – 60 Hz alongside standard KNX bus power (≤10 mA), the device maintains exceptional energy efficiency with a standby consumption of approximately 0.8 W. System integrators and consultants can leverage its configurable parameters, such as a 0 – 20 minute switch-on delay, to deliver optimized lighting control strategies that align with modern energy management standards.
