ETC Sensor3 CEM3 - Dimmer Curves; Linear and Modified Linear Curves

System Reference 21
Dimmer Curves
Dimmer curves determine voltage output in response to control signal input. To accommodate
designer preferences and load response variations, Sensor3 offers several dimmer curves, which can be
applied to individual dimmers (see
Curve on page 18 ).
The available curves in CEM3 are as follows.
Linear
The linear curve matches the control input percentage to Root Mean Squared (RMS) voltage output.
Each percent increase in control level increases dimmer voltage output by the same amount.
Modified Linear (Mod-Linear)
A modified linear curve reduces the voltage change at low control levels for better performance in
low-wattage fixtures.
