Production TST2-O, TST2-OR, TST2-2O and TST2-2OR.

Three-phase-single-phase filtercartridge transformers TST-ABOUT, with the output rated voltage 220V autotransformer embodiment are three-phase voltage-balun TST2, in which the conclusions for the connection of single-phase load is applied one of the phases and the zero output of this transformer. In this case, the balun transformer converts the three-phase to single-phase. In this case the supply network perceives a single-phase load, is enabled through a balun transformer as three-phase.
Three phase-single phase filtercartridge transformers TST2-O, with the output rated voltage 380V in autotransformer version are special balun transformer in which the output for the connection of single-phase load is applied two output windings of the transformer. In this case, the balun transformer converts the three-phase to single-phase with an output voltage of 380V. In this case the supply network perceives a single-phase load, is enabled through a balun transformer as three-phase. An approximate distribution of single-phase power in phases of three-phase mains supply at a ratio of 2:1:1.
Three-phase-two-phase filtercartridge transformers TST2-2O, with the output rated voltage 380V in autotransformer version are special balun transformer, in which the pins to connect the first load is applied, the two output windings of the transformer, and the pins to connect the second load - two output phases of the device. In this case, the balun transformer converts the three-phase to two-phase with an output voltage of 380V. This supply network perceives these two symmetrical loads, enabled via the balun transformer as three-phase. An approximate distribution of single-phase power in phases of three-phase mains supply at a ratio of 1:1:1.
Filtercartridge transformers TST2-O and TST2-2O ensure the conversion of the three-phase network without galvanic isolation.
Used for matching (electromagnetic compatibility) powerful single-phase loads from the mains supply limited power, including Autonomous sources of electric energy, the redistribution of the currents in the three phases and to reduce the load on the work of other responsible consumers.
Filtercartridge transformers TST2-OR and TST-2OR provide galvanic isolation from the mains supply and the nominal voltages different from the voltages of 220V and 380V, such as 12V, 24V, 36V, etc.
