Hello !
In order to help, someone, maybe ...
The Durst CLS 450 head use either a transformer : TRA450 or a stabilized
step down power supply EST450. Both contain, internally a relay (220 V
ov 110V ) to turn the lamp on or off. So one can plug any timer to
control the head (the relay draw a little current from it) you only need
the correct plug.
If one need, I own both schematics, and can scan and send them...
Regards
