Description

LTECH MT-300-450-D2D1 is a constant-current LED driver with an adjustable output current of 300–450 mA. Control: DALI-2 DT8. The maximum combined output is 18.9 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.

The two outputs connect warm-white and cool-white LED loads for colour-temperature control. Size both loads together within 18.9 W; do not double the stated output.

Power this module from a separate 48 V DC supply. Do not connect it directly to 230 V mains.

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 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.

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