The dimmer module (1,40) has a programmable microprocessor control device (12,52) and a power stage (23,63) for controlling an electrical load (2) using a phase-chopping principle, with parallel connection of the power stages of a master dimmer and a slave dimmer, A phase detector (5,45) detects the time characteristic of the half waves of the master phase of the master dimmer, with corresponding control of the control device for providing shortened dimmer half waves supplied in parallel to the electrical load.
