Description

LTECH SE-12-100-400-G1T is a constant-current LED driver with an adjustable output current of 100–400 mA. Control: TRIAC / ELV (leading and trailing edge). The maximum output is 12 W.

Select the output current with the driver’s DIP switches. Disconnect power and set the switches according to the original datasheet diagram for the required current. This model is not programmed with NFC Lighting.

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 manufacturer specifies dimming down to 0.1%. Actual dimming performance also depends on the selected dimmer and LED load.

Displayed stock is LTECH Europe supplier stock, checked on 29 September 2026. Confirm lead time when enquiring.

Current, voltage and available power

Set the LED module current using DIP switches on the driver. 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.
