The DUS® IP20 trunking system is based upon a variable modular system principle that is able to adapt flexibly to complex lighting tasks. The system consists of two basis elements: a 5 or 7-core wired trunking rail and the open distribution light inserts for T26 or T16 fluorescent lamps. This basis can be extended with further system elements such as socket outlet modules, emergency lighting units, spotlights, tracks and fixed covers. All components have been designed for 307mm system dimensions and can be combined and positioned as required with IP20.

Various light effects are created with different optical components such as specular reflectors and louvre inserts. A high-output Power Module for especially ergonomic lighting with four T16 lamps and brilliant HDP® prismatic optics is also available. All system components can be combined without use of tools. X, T and L connectors expand the system’s application range.

• modular construction system
• high flexibility with 307mm system module size: all elements within the DUS® product family have been constructed for this system module size of 307mm and with IP20 can be combined and positioned within this system as desired
• arrangement as a single luminaire, as a trunking system or with a two-dimensional luminaire configuration with up to 4 rails attached to one system node
  Lighting technology
• various lighting technologies ranging from open lamp distribution to CAT2
  Luminaire insert
• inserts available as standard as dimmable variation
• emergency light functions available as standard
• multiple circuits and phase selection possible as standard
• electrical and mechanical connection of inserts within rails without tools in one step
• tool-free rapid mounting via simple-to-use twist-lock catches for secure fixing of luminaire inserts and reflectors
• twist-lock catches for locking of luminaire inserts and reflectors of plastic-coated metal; this gives increased safety in case of fire
• relamping without tools
  Trunking rail
• wiring variations to 7x2.5mm²
• electrical feed possible in central area of a trunking rail arrangement at every trunking rail element
• large distances between suspension points to 3.5m with self-supporting trunking rail connectors
