Three-phase automatic device: characteristics, purpose, connection

Three-phase type automatons are introductory switches. Devices in AC and DC circuits are used. The standard model consists of a set of expanders. The process of switching them is based on changing the frequency in the circuit. Modulators are integral elements of automata. They consist of resistors, as well as capacitors.

Wired modifications have a stabilizer. Triodes in devices are designed to transmit a signal to the central unit. Regulators for modifications are used single-channel, and two-channel type. Insulators for the protection of the system are applied with overlays. To increase the power of the machine, converters are needed.
