Three-phase control units ELFIStor 3F are designed for wireless electric power control in power AC circuits. Applied mainly where the fluent power regulation, current limitation or fluent starting-up is required. The most common applications include power control electrical heating devices, such as electric stoves, high power heating illuminators. The most common applications include power control electrical heating devices, such
as electric stoves or heaters with high powers. ELFIStor Units 3F are suitable for regulating the heating elements with a large temperature coefficient of resistance or for resistance heating premises by direct current passage. Other application possibilities is the control of electric chemical processes applications. Applied as the control unit for slow start up drives with asynchronous motors. The main fields of application are the glass industry, metallurgy, ceramic production, electrochemistry, food, lighting and construction of electric furnaces.
