KNX dimmer 2 chaînes 12-48 Vdc Tunable White

ORDERING CODE EK-GD2-TP-2-LV DESCRIPTION The EK-GD2-TP-2-LV 2-channel KNX 12/24/48 Vdc Tunable White (TW) dimmer allows PWM brightness control of monochromatic and CCT LED loads with white color temperature adjustment. Designed specifically for dimmable LED strips and loads, it is KNX-compatible and suitable for use with two individual channels or with dynamic TW (warm or cool) white color temperature control on a single channel, consisting of two coupled channels. Installation is simple via DIN rail mounting, ensuring seamless integration into electrical panels. The device features an integrated SELV 30 Vdc bus communication module, KNX-certified. FUNCTIONAL FEATURES - ON/OFF control and brightness adjustment of individual or grouped lighting fixtures - Output PWM frequency selection from ETS, from 250 Hz to 6 kHz - Two configurations available: 1 coupled TW channel, or 2 independent channels - TW function: allows you to control two LED strips, one warm white, the other cool white, so that by appropriately adjusting the brightness of each channel, you can gradually switch between the minimum and maximum white color temperature - Outputs can be connected in parallel to increase output power - On/off fade time, minimum and maximum brightness level, linear or logarithmic dimming curve can be set from ETS - Soft or instant on/off, with adjustable delay - Behavior configuration after power restore, bus ON/OFF, download via ETS - Channels can be set from ETS as independent, in parallel, or with copy function from another channel - Lock function Forced operation, staircase lighting, scenarios, night mode, counter, and logic functions for each channel, configurable via ETS. - Automatic temperature adjustment based on light intensity: as the brightness decreases, the color temperature of the strips connected in TW warms, gradually changing from a neutral white to a warmer, more intense color. - Power failure alarm. - Auxiliary output function via external relay with status indication via KNX. - Installer mode (with KNX bus active): pressing the programming button for approximately 2 seconds activates/deactivates the programming LED and load LED flashing approximately every 1 second.
