The device includes execution unit (3) and current feedback unit (4) connected in series in the current circuitry of the reactive load (1). The signal of unit (4) is fed to one of the inputs of the pulse-phase control unit (6), to a second input to which the output of preset unit (8) is coupled. The output of unit (6) is connected to the control input of the executive unit (3) including a TRIAC. Unit (4) includes a low-Ohm resistor. The output of the voltage synchronization and correction unit (10) is connected to a third input of unit (6) and is formed of a resistor (20) connected between the input and output of the unit, and two Zener diodes (21, 22) connected in opposite direction, disconnectably coupled between the unit output and to frame. 4 claims, 3 figures
