LED DALI PS BUS Power Supply - User Manual Item No.: LC-004-100 Item No.: LC-004-200 Item No.: LC-004-150 1. Product Description The DALI PS is suitable for powering a complete DALI circuit with 64 standard DALI devices. The DALI-line is used for the transmission of data as well as for the supply of DALI-modules. DALI signals are not SELV. Therefore the same procedures should be applied as working with mains voltage. 2. Specifications Supply Supply Voltage supply frequency maximum load output type maximum output current Dimensions (L x W x H) grid 120/240VAC 50/60Hz 4W DALI 230 mA 120,2 x 41 x 21,6mm Weight Mounting 76g DIN Rail (DALI PS:LC-004-200) , in ceiling void (DALI PS1:LC-004-100) fitting in luminaires (DALI PS2:LC-0404-150) 3. Description The DALI-line is used for the transmission of data as well as for the supply of DALI-modules. The modules are powered by the DALI-line itself. Therefore a central power supply like the DALI PS is required. The DALI PS differs from typical power supplies in terms of the requirements for short circuit protection and dynamic behaviour for DALI communication. Since standard DALI-ballasts (max. 64 on a DALI-line) may have a maximum supply current of 2mA, the DALI PS is capable to additionally supply DALI control devices (like DALI MC, DALI GC, …) or interfaces that require higher supply currents (like DALI 0-10V, DALI RM, etc.). 4.
