Description
LTECH LU-75-500-1750-U1D2 is a constant-current LED driver with an adjustable output current of 500–1750 mA. Control: DALI / DALI-2 / Push DIM. The maximum output is 75 W.
Program the current with the separate LT-ISET programmer through the SET PORT while the driver is disconnected from power. The factory setting is 500 mA. This model does not use NFC Lighting. Full 75 W output is available within the manufacturer’s stated 1380–1750 mA full-power range; at lower current, LED load voltage limits available power.
Input is 100–240 V AC; the manufacturer restricts 277 V AC operation to North America.
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.
