L5508D1AP Schneider Clipsal C-Bus 8 Channel 1A Leading Edge Dimmer DIN Rail 240V Without Power Supply

The L5508D1AP is a DIN rail mounted leading edge dimmer from the Clipsal C-Bus range, configured with eight independent channels at 1 A each. The trailing P in the part number indicates this version does not contain a C-Bus power supply, requiring a separate unit to energise the bus. This makes the module ideal for panels where power is already provided elsewhere. Leading edge phase control is designed for incandescent lamps, mains voltage halogen, and low voltage lamps fed from conventional wire wound transformers. Eight channels in a twelve module wide enclosure provide dense lighting control from a single panel position.

Panel design must address the power supply requirement before ordering dimmers, as the number of C-Bus power supplies depends on total network current rather than the number of dimmer modules. When replacing a module, the C-Bus network address and group addresses must be reapplied. For live systems, connect the addressing tool before removal to read and replicate the previous configuration.

• Like-for-like replacement in older C-Bus installations in Australia and New Zealand
• Hotels and function venues with numerous small incandescent or mains halogen groups
• Restaurants and bars with decorative lighting schemes requiring leading edge dimming
• Residential projects with existing C-Bus infrastructure needing additional dimming capacity
• Retrofit work in heritage and hospitality buildings where lighting loads cannot be easily changed
