Amplitude dimming technology
LC45iC-DA-100-900 LED driver implements amplitude dimming technology across whole dimming range. Amplitude dimming offers
the best available technology for dimming the light output in an accurate and flicker-free way to ensure high quality lighting in even
the most demanding situations such as camera recording applications. Amplitude dimming technology complies with IEEE 1789-2015
recommendations of current modulation to mitigate health risks to viewers.

Dynamic range in colour temperature control
LC45iC-DA-100-900 LED driver is ready to be used out of the box.
Highest precision and color consistency in controlling combinations of different luminaire types is achieved by setting colour temperatures
and lumen outputs before use with Helvar driver configurator. The configured colour temperatures of the channels should match the ones
of the LED modules used. The factory default settings of cool and warm channels are 6500 K and 2700 K accordingly.
After setting up the colour temperatures, the lumen output values of full dimming level (100 %) should be configured for both channels. By
default, output currents are set to be equal in both channels.
