Sosen 40W Treiber AstroDim 1-10V 100–277V für LED Straßenleuchte

Why choose the Sosen 40W AstroDim driver

Sosen is a well-regarded driver manufacturer trusted by street lighting professionals across Europe. This 40W unit combines a wide universal input voltage with built-in AstroDim functionality, meaning luminaires can follow a pre-set dimming curve tied to astronomical time — reducing energy consumption during low-traffic hours without any additional hardware or communication infrastructure.

• Efficiency: A wide 100–277V input range makes this driver compatible with virtually any mains supply across the EU, simplifying procurement for multi-site or cross-border projects.
• Control: Integrated AstroDim allows autonomous, time-based dimming via the 1–10V interface, eliminating the need for a central management system on smaller installations.
• Compatibility: Designed specifically for LED street light housings, this driver fits standard replacement slots and works with the LED modules already installed in most common luminaire bodies.
• Reliability: Sosen drivers are built for continuous outdoor duty cycles, with protections against overvoltage, overcurrent and short-circuit conditions that extend the service life of the full luminaire.

Where to use it

This driver is suited to street lighting columns, urban road luminaires, car park pole lights and pathway fittings where autonomous dimming is required but a full telemanagement network is not justified. It is particularly practical for retrofit projects on residential roads, industrial estate perimeters and municipal footpaths where energy savings during late-night hours are a priority.

What the specifications mean in practice

• 40W output: Matches the power demand of a standard 40W LED street light module, making this a direct replacement without requiring luminaire modification.
• 100–277V input: Covers single-phase supplies from 100V to 277V, so the same driver stock works across Belgian, Dutch, German and other EU grid voltages without special ordering.
• AstroDim: The driver calculates local sunrise and sunset times and dims the luminaire accordingly — typically stepping down to 50% or lower after midnight — without any external timer or controller.
• 1–10V dimming: A widely supported analogue dimming protocol that allows integration with external lighting controllers or DALI gateways if a managed network is added later.
• Built-in protections: Overvoltage, overcurrent and short-circuit protection prevent cascade failures in the luminaire, reducing maintenance call-outs and extending overall system life.

Installation and compatibility

The driver mounts inside the luminaire housing using standard fixings and connects via the existing wiring harness in most street light bodies. The 1–10V signal wires allow connection to an external controller if required.
