CLIPSAL L5504D2A Used Working C-Bus System Dimmer Module

Product Overview

The Clipsal L5504D2A is a high-quality, 4-channel C-Bus DIN Rail Dimmer Module designed for the precise control of incandescent and low-voltage lighting loads. As a core component of the C-Bus Home and Building Automation system, this module allows for smooth, flicker-free dimming and sophisticated scene control. Each of the 4 channels can handle up to 2 Amps, making it perfect for residential lighting circuits or commercial mood lighting. This Used Working unit provides a reliable way to maintain or expand your existing C-Bus installation with genuine Clipsal hardware at a competitive price point.

• 4-Channel Dimming: Provides independent control of four separate lighting circuits from a single compact module.
• Leading Edge Technology: Optimized for standard incandescent lamps and iron-core (magnetic) low-voltage transformers.
• Learn Enabled Intelligence: Features C-Bus "Learn" technology, allowing for basic programming and commissioning without a PC if required.
• Soft Start Capability: Gradually increases power to the load, significantly extending the lifespan of connected light bulbs.
• Local Override Control: Equipped with front-panel toggle buttons for each channel, enabling manual testing and control during installation or maintenance.
• Compact DIN Rail Design: Occupies 8 standard modules of space, designed for neat integration into electrical distribution boards.
• Thermal Protection: Includes built-in safety circuitry to protect the module against overheating and over-current conditions.

Item Condition (Used - Working)

• Functional Status: Used - Working. This unit has been professionally salvaged from a functional C-Bus environment. It has been bench-tested to ensure all four channels dim correctly and communicate with the C-Bus network.
• Physical State: Shows signs of previous industrial/residential use, such as minor scuffs on the plastic housing. The terminal screws are clean, and the DIN rail mounting clip is secure.
• Electrical Integrity: The internal C-Bus circuitry is stable, and the unit holds its programmed group addresses reliably.
• Visual Reference: Please refer to the high-resolution images to verify the specific hardware revision and terminal condition; the unit pictured is the exact dimmer you will receive.
