Selecting Dimmer Curves
The dimming curve can be set individually for each 10A channel output. The
QolorFLEX
4x10A
Dimmer has an eight position DIP Switch with two positions for each channel output.

Curve
The LED Curve is the default mode, and is intended for controlling LEDs but may be used for
other specialized loads.
The LED Curve Modes have been optimized for flicker free performance in TV and Film
applications. All settings have been camera tested with motion picture film and digital cinema
cameras. The settings are different to allow compensation for variations in shutter speed and
shutter angle. A camera test is recommended to confirm the correct setting has been selected.
The ISL (Inverse Square Law) Curve is intended for incandescent lamp dimming and is similar
to a conventional mains-powered lighting dimmer curve. The PWM period for ISL is 60Hz.
The NON-DIM function is intended for relays and other devices requiring switched power
without PWM dimming.
The Linear Curve is a simple linear scale that can be used to drive DC integrators or other
devices where linear response needed. The Linear PWM period is 60Hz.
