Designation
Values
Description
Load selection
Automatic
The dimmer detects what type of
load is connected and
automatically selects the
appropriate dimming strategy
(leading edge or trailing edge).
RC load (incandescent lamps,
electronic transformers)
Phase control for resistive and
capacitive loads (LED lamps,
incandescent lamps, halogen
high-voltage lamps etc.).
For electronic
transformers/power units
designated for use with RC mode
dimmers (trailing edge phase
ctrl.).
Note:
When selecting RC mode, a load
detection will always be
performed as a precaution. This
should prevent the dimmer from
being damaged (e.g. wound
transformer) when an L-load is
connected.
The RC mode is actually only
used when no
L-load is recognised.
L-load (wound transformers)
Phase control (leading edge
phase ctrl.) for inductive loads,
e.g. wound transformers.
Not
suitable for electronic
transformers, can lead to a
dimmer overload.
Dimmable energy-saving lamps
with RC response
Generally recommended for
ESL, especially for high loads
(advantage: less heat generated
in the dimmer)
