For further information on the products please refer to the data sheets and theinstallation instructions.<strong>DALI</strong> power supply<strong>DALI</strong> PS / PS1/ PS2<strong>DALI</strong> PS, <strong>DALI</strong> PS1 and <strong>DALI</strong> PS2 are <strong>DALI</strong> power supply modules with a rated current of 200 mA or 240 mA (<strong>DALI</strong>PS2). The modules differ in their casing design; <strong>DALI</strong> PS and <strong>DALI</strong> PS2 are suitable for installation in switchingcabinets; <strong>DALI</strong> PS1 is suitable for installation in suspended ceilings or cavities.The interface of a <strong>DALI</strong> ballast needs a maximum of 2 mA; for 64 individual addresses this means a current of 128 mA.The remaining 72 mA (or 112 mA in the case of <strong>DALI</strong> PS2) can be used for supplying <strong>DALI</strong> control modules withouttheir own power supply (<strong>DALI</strong> GC, <strong>DALI</strong> SC etc.).<strong>DALI</strong> PS2 Standby<strong>DALI</strong> PS2 Standby also has a built-in relay contact. To reduce standby losses, the built-in relay disconnects theballasts from the power supply as soon as all the luminaires have been switched off.As soon as the <strong>DALI</strong> PS2 Standby detects that all the luminaires have been switched off it changes to standby modeafter a user-definable delay and controls a built-in relay. With the aid of this relay the connected units can bedisconnected from the power supply via a contactor. Only the <strong>DALI</strong> control modules are then still in the <strong>DALI</strong> circuit.As soon as a <strong>DALI</strong> control module sends a “Light ON” command the <strong>DALI</strong> PS2 Standby reverts to normal operatingmode and connects the units back to the power supply. The parameters of the <strong>DALI</strong> PS2 Standby, such as delay,monitoring interval etc. can be set using the masterCONFIGURATOR configuration software (V1.12 or higher) (seeReference list).<strong>DALI</strong> Manual | 08-2013 | en21 / 93
