DC voltage transformer for 24V LED light sources with all-in-one function (transformer with built-in PWM dimmer). Dimming via DALI, Push (potential-free), potentiometer (470kOhm) or 1-10V. Selectable memory function (lights up with the last set value) in the event of a power failure, also via push button. 1-10 units can be linked and controlled from one or more locations with spring-loaded push button (potential-free). Two outputs with quick terminals, the entire power can be taken out via one output or divided.
