DALI-2 PS DIN rail, DALI Bus Power Supply Unit 250mA 24033444

DALI-2 Bus Power Supply Unit

DALI-2 PS serves as power supply for the DALI bus system. Standardised voltage and current limitation as well as timing ensure a reliable bus communication. With the output current of up to 250mA and entire DALI line can be supplied. Up to 64 addressable DALI devices and an additional 20 to 30 control modules (DALI Sensors, MC, Touch panel…) can be connected. Units with different output current and housing are available, suitable for DIN rail mounting, remote ceiling installation (housing with strain relief) or flush-mounted installation boxes.
