Product Description:
The PSI6300.000-L1 is a medium frequency inverter manufactured by Bosch Rexroth Indramat within the PSI Frequency Inverters series. Designed for industrial automation, the unit converts three-phase mains power into a controlled medium-frequency output so that resistive and inductive loads can be driven with accurate timing and current profiles. It is intended for applications that require repeatable energy delivery and stable process control.
The inverter is connected to a three-phase supply in the range of 400 - 480 VAC, allowing installation on factory power systems. Internally, it uses a switching clock of 1 kHz; this frequency sets the output granularity and keeps transformer size moderate. With a protection rating of IP20, the electronics must be housed in a closed cabinet, but finger-safe access to terminals is provided. When operated at maximum power, the converter dissipates 170 W to the control cabinet, so forced ventilation is recommended. Because the air used to cool the heat sink must remain at or below 45 °C, external ducting must keep the intake temperature within that limit. Air-cooled operation removes up to 360 W of heat. A time resolution of 1 ms governs the sequencer, and up to 256 stored programs permit rapid changeover of process parameters. The nominal system current is 110 A, matching mid-size welding transformers.
During high-demand intervals, the inverter can supply 800 A of primary output current, and the corresponding secondary circuit may experience peaks of 36 kA when connected to a suitably matched transformer. Line and load conductors up to 50 mm² can be clamped in the power terminals, providing the cross-section required for those currents without undue heating. The minimum squeeze time of 16 ms lets the integrated sequencer synchronize current ramps with mechanical actuators used in welding or press equipment. Continuous operation is permitted until the heat sink reaches a maximum of 55 °C; beyond this point, the control logic initiates derating to preserve semiconductor integrity.
