DALI Bus Power Supply
Specialized power supply providing the operating voltage and current required by the DALI bus.
A DALI bus power supply provides limited supply current to the two-wire DALI communication line. It may be a standalone device or a function integrated into a controller or gateway.
Principal characteristics include rated and maximum bus current, output voltage, number of supplied lines, short-circuit withstand, overload behaviour, and automatic restart. Isolation from mains supply and protective characteristics are also important.
Selection criteria include total current consumption of DALI devices, line length and conductor size, voltage drop, operation with multiple power supplies, and compliance with applicable IEC 62386 bus-power requirements.
This subcategory includes standalone and integrated DALI bus power supplies for lighting-control systems.
