Electric flush-mounted installation device for brightness control in an illumination device

摘要

The installation equipment has terminal block (2) in mounting insert that is connected to phase conductor (L) of an alternating voltage network and load conductor (L') of lighting system (18). The lighting system is connected to neutral conductor (N) of alternating voltage network. An adjustment unit (9) in an operating unit is connected to terminal block through an inductance-capacitance (LC) filter (3). The adjustment unit is controlled by a microcontroller (8) to adjust the duty cycle of the high frequency clocking of the main alternating voltage.
