Diagrams and Connections

Wiring Diagram

The wiring diagram illustrates the connections for the driver. It shows input terminals for AC Line (L) and Neutral (N), and output terminals for LED positive (+) and negative (-). It also includes connections for an NTC thermal sensor and the DALI bus lines (DA1, DA2). A DIP-SWITCH is present for configuration.

DALI Diagram

The DALI diagram specifically shows the connection of the DALI bus lines (DA1 and DA2) to the driver, facilitating communication with DALI control systems.

Operation Modes

DALI Dimming: Supports 0/0.5% to 100% dimming with memory function for scenes or light groups, recall of stored functions, and compatibility with standard DALI interfaces. Designed for DALI-2 systems.
AM+PWM Dimming (Default): The default setting is AM+PWM, with 1-25% PWM at 2 kHz and 25-100% AM.
PWM Dimming: Full PWM dimming (240 Hz, 1-100%) can be activated by short-circuiting the NTC port during driver startup. The same procedure resets the driver to AM+PWM mode.
AM Dimming: Full Amplitude Modulation dimming (1-100%) is also supported.
