Capacity: 300 kVA (kilovolt-amperes). Phase: Three-phase, with a four-wire system. Input Voltage: Typically a wide range, such as 175V-265V (phase voltage) or 304V-456V (line voltage), but often customizable to specific needs (e.g., \(380V\pm 20\%\)). Output Voltage: A stable, regulated output, commonly \(380V\) or other standard voltages like \(400V/220/230/240/415V\), often with an accuracy of \(\pm 2\%\) or \(\pm 3\%\). Regulation Type: Automatic, using technologies like servo motors or static (thyristor/IGBT) control. Efficiency: High efficiency, often greater than \(95\%\). Protection: Includes comprehensive protection against over/low voltage, overheat, overload, and short circuits. Some models have optional protection for phase failure and inrush surges.
