KNX dimmer 4 chaînes 12-48 Vdc Tunable White

ORDERING CODE EK-GD1-TP-4-LV-T DESCRIPTION The ekinex EK-GD1-TP-4-LV-T 4-channel KNX Tunable White (TW) dimmer, 12/24/48 Vdc, allows PWM brightness control of monochromatic and CCT LED loads with white color temperature adjustment. Specifically designed for dimmable LED strips and loads, it is compatible with the KNX system and suitable for use with 4 single channels or with dynamic white TW color temperature control (warm or cold) on 2 channels, each consisting of 2 coupled channels. Installation is simple via DIN rail mounting, ensuring seamless integration into electrical panels. The device has an integrated SELV 30 Vdc bus communication module, KNX certified. FUNCTIONAL FEATURES - ON/OFF control and dimming of individual or grouped lighting fixtures - Output PWM frequency selection from ETS, from 250 Hz to 6 kHz - Available configurations: 2 TW-coupled channels, 1 TW-coupled channel and 2 independent channels, or 4 independent channels - TW function: allows you to control two LED strips, one warm white and 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. - Fade time on and off, minimum and maximum brightness level, linear or logarithmic dimming curve can be set from ETS. - Soft or instant on and off, with adjustable delay. - Behavior can be configured after power restore, bus ON/OFF, or download via ETS. - Channels can be set from ETS as independent or in parallel. or with copy function from another channel - Lock function, forced operation, stair light, scenarios, night light, counter, and logic functions for each channel, configurable via ETS - Automatic temperature regulation 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 - Manual control with membrane buttons for local ON/OFF testing of channels 1-2-3-4: in manual mode, briefly pressing the button corresponding to a channel activates/deactivates the load; pressing for at least 2 seconds causes the load to flash approximately every 1 second - Relay contact for turning off the AC/DC power supply when the 12/24/48 Vdc outputs are off, or alternatively as an auxiliary output relay - Auxiliary output function via relay with status indication via KNX TECHNICAL DATA Inputs - Constant input voltage: 12/24/48 Vdc - Input voltage: Power supply: min: 10.8 Vdc .. max: 52.8 Vdc Outputs - PWM voltage output 12/24/48 Vdc - Output current: 6A for a single channel, or 12A for 2 channels connected in parallel - Rated power per channel @12Vdc: 72 W - Rated power per channel @24Vdc: 144 W - Rated power per channel @48Vdc: 288 W Dimming - PWM dimming mode in the range 250 Hz ÷ 6 kHz - Dimming range: 1-100% Environmental conditions and other characteristics - Operating temperature: -20°C ... + 40°C - Storage temperature: -40°C ... + 60°C - Transport temperature: -40°C ... + 60°C - Max. Enclosure temperature (tc): 65°C - Relative humidity: 91% non-condensing - Degree of protection: IP00 (IP20 in junction box or electrical panel) - Power and load wiring: 0.2 ÷ 4.0 mm2 (24 ÷ 11 AWG) for single wire / 0.2 ÷ 6 mm2 (24 ÷ 9 AWG) for stranded wire - KNX bus wiring: 0.6 ÷ 0.8 mm2 (19 ÷ 18 AWG) - Wire stripping: 8.0 mm - Plastic enclosure - Device for panel mounting on a 4-UM DIN rail - Weight: 200 g - Dimensions (W x H x D): 71 x 91 x 62 mm SUPPLY The supply includes a terminal for connection to the bus line.
