Dimming actuator, 4-gang Standard
Load type
The dimming principle of the dimming channel is specified here.
– universal (with automatic calibration procedure):
The dimming channel automatically sets the connected load type. After pro-
gramming, after bus voltage return (without mains voltage) or after switching
on the mains voltage supply of a load output, the actuator calibrates itself
automatically to the connected load. The calibration procedure becomes no-
ticeable during ohmic loads by a brief flicker and lasts up to 10 seconds de-
pending on the network conditions.
– electr. transformer (capacitive / trailing edge phase control):
The dimming channel is set to the trailing edge phase control principle. Ohmic
loads or electronic transformers can be connected to the output.
– conv. transformer (inductive / leading edge phase control):
The dimming channel is set to the leading edge phase control principle. Con-
ventional transformers can be connected to the output.
– LED (trailing edge phase control):
The dimming channel is set to an optimised trailing edge phase control prin-
ciple. HV LED or compact fluorescent lamps optimised for this dimming prin-
ciple can be connected to the output.
– LED (leading edge phase control):
The dimming channel is set to an optimised leading edge phase control prin-
ciple. HV LED or compact fluorescent lamps optimized for this dimming prin-
ciple can be connected to the output.
Minimum brightness
The step value set here is a gauge for the minimum adjustable residual phase angle
of the output signal.
The value set here cannot be undershot in any switched-on operating state of the
dimming channel, i.e. under no circumstances can the light be dimmed darker than
the value set here.
