Description

LTECH SE-20-100-700-W1D is a constant-current LED driver with an adjustable output current of 100–700 mA. Control: DALI / DALI-2. The maximum output is 20 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.

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.

The current rows are selected reference points from the operating envelope, not fixed switch positions or an exhaustive manufacturer settings table.

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.
