The ST-A 30/9000A-3-ST W is a mounting power rail with data bus with a length of 3000 mm, specifically developed for integration into ONETrack systems. As a 6-conductor rail, it offers three separately switchable circuits, enabling flexible and secure power supply for different loads. The rail is ideal for implementing lighting applications with DALI technology, allowing central control and dimming of luminaires. The extruded aluminum profile serves not only as a carrier but also as a protective conductor, enhancing electrical safety. On-site length adjustment is easily possible, requiring the cutting tool ST-ZCUT/S-9000/T-N to shorten the copper conductors. Simple ceiling mounting is achieved via pre-punched elongated mounting holes, ensuring quick and secure installation. The rail is also compatible with 3-phase power rail adapters without bus function, extending system compatibility.
