Product Description:

The PSI64C0.758-W1 medium frequency inverter from Bosch Rexroth Indramat was designed with a special focus on aluminum applications that require up to 80 kA. It is capable of supporting a variety of welding modes, including, repeat, spot, and seam welding, as well as adaptive control options such as PHA and KSR. MainWLD operations are equipped with an optional UIR, which renders them adaptable to a variety of applications. The PSI64C0.758-W1 medium frequency inverter operates with a line voltage range of 400 to 480 volts and can handle a nominal mains current of 220 amperes. At 1000 Hz, the main voltage output is calculated by multiplying the line voltage by the square root of 2. The highest primary current discharge that the system can provide is 1600 A. The system is ideal for industrial-grade welding because of its water-cooled design; it regulates temperature and guarantees stability throughout long operations. Because of its small size, it can be easily included in systems that have limited room. The dependable performance of this water-cooled inverter, that is enabled by its compatibility with PSG 6000 series MF transformers, is not limited to welding and material processing; it is employed in a multitude of industrial applications. 

The PSI64C0.758-W1 is designed to withstand substantial thermal loads, thereby guaranteeing dependability and efficiency. It is capable of withstanding voltage tolerances of -15% at 400 V and 10% at 480 V. The cross-sectional area of the connection must be 95 mm2 for the transformer and mains connections. Superior accuracy and dependability are assured by an advanced cooling system, which maintains a constant performance level over long periods of time.
