3.2 Electronic control gear/LED module combination
PrevaLED ® Core Z3 LED modules can either be used with
constant-current control gears or in combination with
OSRAM OTi control gears. The OTi control gears provide a
thermal shutdown function as well as an automatic fl ux cali-
bration. Constant- current control gears do not provide these
features. The table below shows possible combinations of
PrevaLED
® Core Z3 LED modules and OSRAM ECGs.

Preliminary data. The fl ux levels realized with fi xed-value constant-current OTe and OT FIT drivers will change as the effi cacy of the modules evolves.
