Profile Name
Characteristics
IES
IES Square Law
Default setting for most lighting require-
ments – provides linear light output in
relation to DMX512 level for most lighting
loads.
SL
‘S’ Law
Used for some early thyristor dimmers in
theatre applications. An unsatisfactory
curve, but may be needed to balance
mixed dimming installations.
FLU
Fluorescent
Used for four-wire fluorescent circuits.
Note that heater circuits should be run to
a separate dimmer, which should have a
non-dim or hot setting.
C–C
Cold Cathode
Use for cold-cathode or neon lighting
loads.
Lin
Linear Volts
Linear rms voltage output in relation to
DMX512 levels.
120
120 volt scale
Provides 0–120v output, scaled to
0–100% DMX512 input.
P03
Preheat 3%
Any DMX512 level 3% or below results in
3% output. Above 3% as IES square law.
P05
Preheat 5%
Any DMX512 level 5% or below results in
5% output. Above 5% as IES square law.
N05
Non-Dim 5%
Non-dim – dimmer switches on for 5%
DMX512 level or above. No regulation.
N50
Non-Dim 50%
Non-dim – dimmer switches on for 50%
DMX512 level or above. No regulation.
N95
Non-Dim 95%
Non-dim – dimmer switches on for 95%
DMX512 level or above. No regulation.
Hot
Always On
Dimmer always on, irrespective of
DMX512 level. No regulation.
