Sosen 75W Driver AstroDim 1-10V 100–277V for LED Street Light

Why choose the Sosen 75W AstroDim driver

Sosen is a recognised name in professional LED drivers, and this 75W unit is built specifically for street lighting applications where unattended, long-term operation is the norm. The integrated AstroDim function calculates sunrise and sunset times based on a programmed location, reducing output automatically during low-traffic hours without any external dimming signal or smart-city network required.

• Autonomous dimming: The built-in astronomical clock dims the luminaire according to real sunrise and sunset times, cutting energy consumption during off-peak hours with no additional hardware.
• Universal input voltage: The 100–277V AC input range covers single-phase supplies across the EU and beyond, making this driver suitable for mixed or ageing grid infrastructure without rewiring.
• 1–10V control: A standard 1–10V interface allows integration with external lighting management systems or manual dimming controllers where centralised control is already in place.
• Sosen reliability: Sosen drivers are used in professional street and area lighting installations worldwide, with robust thermal management and protection against overvoltage, overcurrent and short circuit as standard.

Where to use it

This driver is the correct replacement or upgrade unit for 75W LED street lights on urban roads, residential streets, car parks, industrial access roads and perimeter lighting columns. It is equally suited to new installations where an autonomous dimming schedule is preferred over a networked control system, particularly on sites where running cabling for a separate dimming signal is impractical.

What the specifications mean in practice

• 75W output: Matches the power demand of a standard mid-range LED street light module, ensuring the luminaire operates at its rated lumen output without overdriving or underdriving the LEDs.
• AstroDim: The driver calculates local dawn and dusk automatically once programmed with GPS coordinates, so dimming schedules adjust throughout the year without manual intervention.
• 1–10V dimming: This industry-standard signal interface means the driver can be controlled by virtually any compatible lighting management system, DALI gateway or simple analogue dimmer.
• 100–277V input: Full compatibility with both low and high single-phase voltages means one driver SKU covers installations across different countries and older grid supplies without modification.
• Sosen brand: Sosen drivers carry recognised quality certification and are a like-for-like replacement in many existing street light housings, simplifying maintenance and spares management.

Installation and compatibility

The driver fits into standard street light housings with a conventional wired connection to the LED module and mains supply. AstroDim scheduling is configured via the driver's programming interface before installation. The 1–10V terminals connect directly to any compatible control system.
