Actuators represent the operated thyristor three-phase regulator of alternating current with system of regulation (analog or microprocessor), protection and alarm systems. Are intended for control of asynchronous engines and switching in chains of alternating current. Provide smooth start-up, parametrical regulation of speed and protection of the electric motor against overloads, against break of a phase. Possess high reliability with the increased switching frequency, durability. Give considerable decrease in operational costs in comparison with the contact equipment. Smooth start-up allows to exclude undervoltage of a network at launch of powerful electric motors. Provide regulation of frequency of rotation of mechanisms with the ventilatory moment on a shaft (pumps, fans) in the full range.
Reversive actuators provide a reverse (change of the direction of rotation) of the engine by contactless switching of phases with the set tokoogranicheniye.
