Product Description:
The PSI63C0.789-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. As a power conversion unit, it modulates three-phase supply energy so that welding transformers, inductive heaters, or similar loads receive precisely timed current pulses for automated cells. The device integrates with factory networks, allowing motion controllers or PLCs to trigger high-current sequences while the internal architecture manages switching events on a millisecond scale. This operating method supports repeatable energy delivery in processes that depend on tightly timed output rather than simple line-frequency switching.
The inverter’s control loop updates every 1 ms, allowing tight regulation of output amplitude and phase during rapid process changes. A water-cooled baseplate transfers switching losses to an external circuit so cabinet air remains stable, while the TriCore CPU handles interpolation, fault supervision, and analog conversion. Line-side wiring must accommodate 110 A of mains current across an input range of 400 to 480 VAC. With a compatible PSG3100 welding transformer, the step-down stage can deliver up to 36 kA on the secondary side for demanding welding pulses.
Peak demand on the internal switches is limited by a 800 A primary current ceiling, and the PROFINET interface exchanges cyclic data with Ethernet-based timers so twenty-four point-address inputs can trigger independent schedules. Sequence repetition up to 1000 Hz lets short welds be stacked without loss of phase accuracy, while the buffered 128 I/O port group handles auxiliary clamps and sensors. Installation requires at least a 35 mm² supply conductor, because a smaller wire gauge can increase cable losses and may trip overcurrent protection, and the screw terminals accept cable lugs up to 50 mm². A minimum coolant flow of 4 l/min must be maintained to avoid thermal cutout during sustained operation.
