Method for detecting the disconnection of a load from a dimmer
The method involves measuring a voltage between a phase and an output of a supply stage. A fraction of the voltage is compared with a fraction corresponding to a preset threshold voltage which is lesser than a peak voltage of a power grid. A dimmer is blocked in a non supply state of a load if the m...

| Zusammenfassung: | The method involves measuring a voltage between a phase and an output of a supply stage. A fraction of the voltage is compared with a fraction corresponding to a preset threshold voltage which is lesser than a peak voltage of a power grid. A dimmer is blocked in a non supply state of a load if the measured voltage is lesser than the preset threshold voltage, where value of the threshold voltage is comprised between fifty and two hundred peak volts. An independent claim is also included for a device for detecting disconnection of a luminous load from a dimmer connected to a power grid. |
