Product Description:
The PSI 6300.740L1 belongs to the PSI Frequency Inverters series manufactured by Bosch Rexroth Indramat. It is a medium-frequency inverter that modulates three-phase power to drive induction heating, hardening, or similar processes requiring adjustable kilohertz-range energy. Within automated production cells, the unit acts as the link between a 400 VAC utility supply and specialized coils or transformers, providing regulated current while reducing the effects of reactive loads on upstream electrical equipment.
The power section accepts a nominal input of 400–480 VAC at line frequencies of 50 or 60 Hz, so it can be wired directly to common industrial mains without transformers. An integrated 24 V auxiliary supply delivers up to 24 VDC and 2 A for contactors, sensors, or small PLC modules, eliminating the need for a separate control power transformer. Heat generated by switching devices is removed through an air-cooled channel, and thermal losses are limited to 360 W to reduce the cooling demand inside the cabinet. Airflow helps maintain semiconductor junction temperatures, while the inverter’s medium-frequency topology keeps output waveform distortion low and supports precise energy transfer to the load.
The enclosure and operating limits are suitable for standard control cabinets. A degree of protection of IP20 guards users against contact with live conductors while allowing airflow across the heat sink. Continuous operation is permitted from +10 to +55 °C, while storage or transportation is permitted from -25 to +70 °C. The climatic category is 3K3 under EN 60721-3-3, indicating tolerance of moderate humidity and the noncondensing conditions commonly found in factory buildings. The unit has a mass of 20 kg, allowing it to be mounted in a control enclosure while leaving space for line reactors or EMC filters.
