LTECH 20W DALI-2 DT8 Tunable White Driver, 2 Channel

Name: LTECH 20W DALI-2 DT8 Tunable White Driver, 2 Channel
Brand: Nuordic
SKU: SE-20-100-700-W2D
Price: 108.00 USD
Availability: InStock

Model SE-20-100-700-W2D

The LTECH 20W DALI-2 driver runs tunable white fixtures on two channels, as DT8 color temperature or in DT6 modes, with output current set from 100 to 700mA over NFC and dimming to 0.01% without visible flicker. Its slim plastic case passes a 48mm hole, so it fits through a 2 inch downlight cutout.

Standard configuration

This product ships one way; there is nothing to configure.
