Operating control device for operating a light

摘要

The controller (5) has an input circuit (8) divided into a primary circuit (10) and a secondary circuit (11). The primary circuit is attached to an alternating current voltage source (9), and the secondary circuit is galvanically separated from the primary circuit. The secondary circuit has a supply voltage (UV) for an output circuit (7), and a power factor correcting circuit (25) has a control circuit (26) arranged in the primary circuit or the secondary circuit. Primary-sided primary voltage (UP) and the supply voltage are supplied to the control circuit as input parameters.
