DBPSU
DALI / DSI Power Supply Unit (DBPSU) is designed for use with
DANLERS DALI or DSI dimmable devices.
The DALI / DSI Power Supply Unit is rated at 40mA (DALI standard
allows 250mA maximum). The controls interface of a DALI ballast
normally sources at 2mA.
Individual DALI / DSI circuits must not exceed 40mA.
Standard 2-core mains cable of minimum guage 1.5mm2is
recommended.
The maximum cable length of the DALI / DSI signal wires must not
exceed 300m or drop more than 2V on the signal line voltage.
To minimise voltage drop on the cable, the DBPSU can be installed
at the middle of the system so the cable is split into 2 equal lengths.

Wiring connections
To control more than 20 ballasts (64
max) additional DBPSU can be installed
in the middle of the system with cable
split into equal lengths to minimise
voltage drop. Polarity sensitive when
installing multiple DBPSU.
