DALI PS serves as power supply for the DALI bus system. Voltage and current limitation according to standard as well as timing ensure a reliable bus communication. With the output current of up to 250mA an entire DALI line can be supplied. Up to 64 addressable DALI devices and additional 20 to 30 control modules (DALI Sensors, MC, Touch panel...), up to an overall load of 200mA 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 ush-mounted installation boxes.
