Product Description:

The PSI64C0.720-W1 medium frequency inverter from Bosch Rexroth Indramat is manufactured to enhance the performance of industrial automation, particularly in aluminum welding applications with a current of up to 80 kA. Under 400 V operation, it allows voltage deviations of -15%, while under 480 V operation, it permits deviations of +10%. The PSI64C0.720-W1 medium frequency inverter can handle a nominal mains current of 220 amperes and can operate within a line voltage range of 400 to 480 volts. One way to ensure accurate performance at 1000 Hz is to multiply the line voltage by the square root of 2. This will give you the main voltage output. The system can only discharge a maximum of 1600 A in primary current. Operational stability and temperature regulation throughout extended durations of operation are guaranteed by the device's design, which is water-cooled. The small footprint of the system allows it to blend in with tight quarters with ease. This inverter's strong performance when used with PSG 6000 series MF transformers makes it a flexible choice for a variety of applications, including welding and material processing. An optional UIR module is available for MainWLD operations that provides the flexibility required to manage a variety of industrial scenarios. A cross-sectional area of 95 mm² is necessary for transformer and mains connections. For any questions or inquiries regarding the supply of this inverter, contact Wake Industrial today.
