DALI-2 LED decoder · external 12–48 V DC · 4 PWM channels · IP67 · NFC
DALI-2 control also works in DALI systems. Available functions depend on the controller.
LTECH LD4 is a four-channel DALI-2 LED decoder for constant-voltage loads, with PWM outputs. It requires an external 12–48 V DC supply. IP67; NFC parameter setting.
Maximum load is 960 W at 48 V and PWM up to 3.6 kHz: up to 5 A per control channel, split across two 2.5 A outputs, and 20 A total. Higher PWM frequencies require a lower load; follow the datasheet load table.
Check the manual and terminal markings before installation.
