DALI / DSI Power Supply Unit (DBPSU) is designed for use with DANLERS DALI / DSI dimmable controls or third party DALI / DSI controls.

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 1.5mm2 is 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.
