HF-ballasts for DSI-control are
only manufactured by Tri-
donic. Control information in
the DSI system is transferred
to the HF-ballast via a non-
addressable digital signal. One
benefit of digital control is that
it is independent of the control
circuit’s length and resistance.
All luminaires connected to the system are controlled in the same
way irrespective of the distance between the control unit and the
luminaire. Digital control also allows more flexible control of the
light sources. As a result, the HF-ballast is regulated according to
the eyes sensitivity.
Apart from the phase, neutral and earth conductors, two other
wires for the control circuit are connected to the luminaire. The
control bus is polarity free, which facilitates installation. The control
and mains voltages to the control unit can be routed in the same
conduit or cable sheath over a length of up to 250 m, as the digital
signal is fairly insensitive to disturbances.
The lighting is switched on and o by means of a digital control
command, permitting the mains voltage to be connected directly
from the fuse panel to the luminaire. There is a constant supply
to the luminaires, even when switched o. The minimum level is
dependent on the type of light source 1 %, 3 % or 10 %.

DSI: smartDIM SM and Sensor II with Shutter switch and HF ballast PCA ECO
A larger system can be created for day-
light control with manual control and
occupancy detection by using Tridonic
smartDIM SM. Manual control with
retractable switches or shutter switches.
Dierent functions for occupancy and
automatic switching on can be selected
by means of DIP-switches on the control
unit. Several sensors can be connected
in parallel, but only one should be con-
nected for daylight control. Maximum
25 HF-ballasts can be connected to one
control. Dierent phases can be used to
the luminaires.
DSI control gear
Tridonic manufactures two ranges of dimmable control gear, Excel
and Eco. In addition to all the features available on the Eco model
the Excel unit also has the capability to interpret DALI commands,
the possibility to program parameters and the ability to transmit
error messages.
Note
DSI control is non-addressable.
The luminaire/group can also be computer controlled using the
winDIM-software. This requires the computer to be connected to
the luminaires bus-system via a winDIM cable. The winDIM soft-
ware is available via the Internet www.tridonicatco.com.
