Description

LTECH SE-40-300-1050-W2D is a constant-current LED driver with an adjustable output current of 300–1050 mA. Control: DALI / DALI-2. The maximum combined output is 40 W.

Set the output current with the NFC Lighting app in 1 mA steps. Disconnect power to the driver before programming, select a current suitable for the LED module and write the setting via NFC. The app configures parameters; everyday dimming uses the driver’s stated control interface.

The two outputs connect warm-white and cool-white LED loads for colour-temperature control. Size both loads together within 40 W; do not double the stated output.

NFC Lighting offers DT8 CT, DT6 CT and DT6 DIM modes. DT6 DIM supports one address/one channel, one address/two channels or two addresses/two channels. Select the mode to suit the DALI controller and connected luminaire.

Check the LED module’s rated current and voltage requirement at full brightness. The Technical specifications tab lists the voltage range at each current and calculated load power: P = I × U. The lower voltage limit describes a compatible LED load, not minimum dimming. The driver’s maximum output limit still applies where a rounded voltage row produces a slightly higher calculated value.

Current, voltage and available power

Set the LED module current using the NFC Lighting app or LTECH NFC programmer. Available power depends on the permitted output voltage at that current: W = V × A. The rated wattage is not available at every current setting.

The table describes the LED load at full brightness, not the lowest dimming level. Power follows current × voltage; also check the driver rating and original datasheet before selecting a load.

Two-channel driver: the power limit in the table applies to both channels combined, not to each channel.
