DALI power supply
DALI PS / PS1/ PS2
DALI PS, DALI PS1 and DALI PS2 are DALI power supply modules with a rated current of 200 mA or 240 mA (DALI
PS2). The modules differ in their casing design; DALI PS and DALI PS2 are suitable for installation in switching
cabinets; 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 without
their own power supply (DALI GC, DALI SC etc.).
DALI PS2 Standby
DALI PS2 Standby also has a built-in relay contact. To reduce standby losses, the built-in relay disconnects the
ballasts 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 mode
after a user-definable delay and controls a built-in relay. With the aid of this relay the connected units can be
disconnected 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 operating
mode 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) (see
Reference list).
