The OSRAM DALI MCU Switch is a wall-mounted rotary dimmer for DALI lighting systems, finished in a white casing. It gives installers a manual control point within a DALI network, working alongside sensors and control panels rather than replacing them.

Key features of the OSRAM DALI MCU switch

• Multiple control points, up to four DALI MCUs can be connected in parallel to set up several rotary control stations on one network.
• Synchronisation, the connected control points synchronise automatically with each other.
• Power consumption, max. 2 W.
• Cable run, the DALI control cable can run up to 300 m.
• Load capacity, suitable for up to 25 ECGs, LED drivers and power supplies.
• Standard compliance, implements DALI edition 2 (IEC 62386 ed. 2).

Applications

Fit the switch where a room or building needs a manual dimming point alongside automated control. It can be combined with standard presence and motion detectors that use a mains contact, and the behaviour after a power failure is configurable during setup. Because it works over the DALI bus, it suits offices, retail units and larger installations where several rooms share one lighting control scheme.

Expansion

The system is easy to expand using DALI repeaters or by adding further DALI MCUs, so a project can grow without rewiring the existing control points.
