Interruptor crepuscular THEBEN LUNA 110 plus AL com sensor de luz de sobrepor, 2-50000 lx, atraso 0-20 min, 1 comutador

With a light measuring range spanning an extraordinary 2 to 50000 lux, the THEBEN LUNA 110 plus AL twilight switch delivers precise, reliable lighting control for any outdoor or indoor application. This analog device pairs a DIN-rail control unit with a surface-mounted external light sensor, ensuring flexible installation and accurate daylight detection. The adjustable switch-on and switch-off delays (0–20 minutes each) prevent false triggering from transient light changes, while the 16 A changeover contact handles heavy loads with ease. Whether managing street lighting, signage, or building facades, this switch combines robust construction with straightforward operation.

Overview

The LUNA 110 plus AL is an analog twilight switch designed for automatic lighting control based on ambient light levels. It consists of two main components: a control unit that mounts on a DIN rail and an external light sensor for surface mounting. The sensor measures illuminance from 2 to 50000 lux, and the switching threshold is adjustable within this range. The control unit features a single changeover contact (SPDT) rated for 16 A resistive load at 250 V AC, making it suitable for switching lighting circuits directly. The device operates on a 230 V AC supply (50/60 Hz) and includes adjustable time delays for both switching on and off, allowing customization to avoid nuisance switching.

What stands out

• Wide light measuring range: 2–50000 lx covers from deep twilight to bright daylight.
• Independent adjustable switch-on and switch-off delays (0–20 min) prevent false operations.
• High switching capacity: 16 A resistive, 10 A inductive, supports incandescent/halogen up to 2300 W and LED up to 600 W.
• Robust protection: control unit IP54, light sensor IP65 for outdoor use.
• Simple screw terminal connections and compact dimensions for easy installation.
