FIELD: electricity. ^ SUBSTANCE: remote control device comprises an amplifier, the output of which is a switching element connected in series with a control coil to an AC voltage source, and a device of AC voltage asymmetry control, comprising an electronic switch, a chain of serially connected resistor and capacitor, connected to outputs of a spark-proof AC voltage source. A shape of auxiliary pulses is added, the output of which is connected to the input of the electronic switch in the asymmetry control device, a diode is connected in parallel to the control coil, being structurally made as non-ruptured, in the asymmetry control device, parallel to the capacitor, there is the second chain connected of serially joined third resistor, output of the electronic switch and input of an optically coupled isolator, output of which is connected to the amplifier input. ^ EFFECT: expansion of functional capabilities, simplification and provision of control line. ^ 9 cl, 4 dwg |
