            Power supplies are executed on the base of variable frequency drives ECT series voltage autonomous invertors.

            Standard ECT4S supplies introduce themselves from alternating to alternating current (AC/AC) converters with voltage and frequency load stabilization.

            Power sources DC/AC (from direct to alternating current), DC/DC (from direct to direct current) are developed and delivered by special request.

      Standard execution main technical features are given in Table 1.

                                                                     Table 1

            Converter control: local – from integrated programmable microcontroller and control panel with display, remote – from external community elements (buttons, relay).

            Static frequency-converter is completed additionally by incoming (outgoing) matching transformer and sinus-filter (option) for outgoing sinusoidal voltage receiving.

            Construction – a cabinet with semiconductor elements, IGBT modules, control system, electromagnetic devices and commutation apparatus. Output filter and matching transformer are placed in the cabinet or separately (by request).

            Power source conditional shorthand structure when ordering:

            Static frequency-converter ECT4S- Х₁/Х₂- Х₃/Х₄- Х₅ - Х₆:

            ECT – series name;

            4 – development ordinary number;

            S – stabilized by frequency (current, voltage – by request);

            X₁/X₂ – output and input current type (direct/alternating) accordingly (is indicated for non-standard fulfillments);

                        DC/AC – from direct to alternating current, DC/DC – from direct to direct current;

            X₃/X₄ – rated voltage, V, on output and input accordingly (is indicated for non-standard fulfillments);

            X₅ – rated output current, A: 10, 16, 25, 32, 40, 63, 80, 100, 160, 250, 400;

            X₆ – rated output frequency, Hz: 50, 60, 200.

Static power sources typical dimensions and weights are given in Table 5.                

                                           Table 5.

            Dimensions are given without outgoing filter and matching transformer consideration. Features of standard and additional optional equipment are coordinated with customer by request.
