FIELD: lighting control equipment. SUBSTANCE: the device additionally has in each channel: a synchronizing circuit, demodulator, integrator, comparator, AND gate, OR gate, inverter, flip-flop, multivibrator, interrupter, pulse-width modulators, timer, pulse-length selector, lighting ON signal conditioner, interruption signal conditioners. The given units in correlation with power transformer, first pulse shaper, second pulse shaper, first thyristor, second thyristor make it possible to control the level of lighting and stabilize the output voltage across load in the conditions of noise in power mains. EFFECT: enhanced noise immunity and operate reliability. 2 dwg
