The modules differ in their casing design; DALI PS and DALI PS2 are suitable for installation in switchingcabinets; DALI PS1 is suitable for installation in suspended ceilings or cavities.The interface of a DALI 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 DALI PS2) can be used for supplying DALI control modules withouttheir own power supply (DALI GC, DALI SC etc.).DALI PS2 StandbyDALI 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 DALI 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 DALI control modules are then still in the DALI circuit.As soon as a DALI control module sends a “Light ON” command the DALI PS2 Standby reverts to normal operatingmode and connects the units back to the power supply. The parameters of the DALI PS2 Standby, such as delay,monitoring interval etc. can be set using the masterCONFIGURATOR configuration software (V1.12 or higher) (seeReference list).DALI Manual | 08-2013 | en21 / 93
