The Erco-Leuchten power rail type 78342000 is a high-voltage power rail system made of aluminium, powder-coated in white (RAL9002), with a total length of 2000 mm. It serves as a supply element for electrical devices, particularly luminaires, in commercial and industrial applications. The system is designed for use in lighting systems operated either via DALI control or as a 3-phase power rail. The power rail is approved according to IEC 60570 (equivalent to EN 60570/VDE 0711 part 300), confirming compliance with European standards for power rail systems.

Applications

The power rail is suitable for use in indoor environments, particularly in office buildings, retail spaces, production halls, and other facilities where a flexible and scalable electrical supply for lighting fixtures is required. The construction allows for the mounting of luminaires and other devices onto the rail, with power supply delivered directly via the rail. The rail can be used either as a DALI system for intelligent lighting control or as a 3-phase power rail for higher power demands.

Functions and Equipment in Detail

The power rail features four insulated copper conductors as well as a pressed-in protective conductor, ensuring electrical safety. The mounting surface is equipped with removable knockouts arranged at intervals of 0.4 metres. These enable flexible and quick attachment of luminaires or other devices to the rail without requiring additional drilling or mounting aids. The knockouts are easily removable, allowing for individual adjustment of mounting points.

Technology Explained Simply

When used as a DALI power rail, a circuit with a rated current of 16 amperes is provided. Additionally, two conductors are integrated for connection to a DALI data line, enabling digital control of connected luminaires. DALI (Digital Addressable Lighting Interface) is a standard for lighting system control that allows individual dimming, grouping, and remote control of luminaires. When used as a 3-phase power rail, three separately switchable circuits, each with 16 amperes, are available. This enables even distribution of electrical load across three phases, which is particularly advantageous for larger installations with high energy requirements.

Compatibility and Accessories

The system is part of the ERCO power rail system and can be combined with other components of this system, such as DALI-compatible luminaires or switching and control devices. The power rail is designed for use with Erco-Leuchten luminaires and compatible devices. The use of non-compatible devices may impair functionality or violate safety standards.

Mounting and Installation

The knockouts on the mounting surface facilitate the positioning of luminaires and other devices. Electrical connection is made via the integrated conductors, with power supplied through the rail. Installation requires compliance with applicable electrical standards and the use of appropriate tools and safety precautions.

Operational Advantages

The power rail provides a flexible and scalable solution for the electrical supply of lighting systems. The option to choose between DALI control and 3-phase operation expands its range of applications. The integrated knockouts enable quick and easy mounting of luminaires, reducing installation time. Approval according to IEC 60570 ensures the safety and reliability of the system in operation.
