Part Code: R911330148-AJ1
Bosch Rexroth PSI 6100 Medium Frequency Welding Inverter is a high-performance frequency inverter used for speed and torque control of industrial motors.
The Bosch Rexroth PSI 6100 (R911330148-AJ1) is a three-phase medium-frequency (MF) welding inverter with an integrated weld timer, used for resistance welding — spot, projection and seam welding. It connects to PSG-series welding transformers to deliver precisely controlled welding current.
Designed for industrial production lines, the PSI 6100 combines the power stage and weld-control functions in one unit, with fieldbus, serial and parallel I/O options for integration. A reliable inverter is critical to consistent weld quality, so a tested spare protects against costly line stoppages.
