Product Description:
The PSI 6300 63C0.728L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. The device converts three-phase mains power into a controlled high-frequency output that energizes induction heating coils, spindle drives, or similar loads that benefit from adjustable power without mechanical gear changes. Within an automated cell, the inverter supplies precise current and voltage waveforms, enabling process parameters such as heat penetration depth, cutting speed, or welding temperature to be varied directly through drive programming rather than by altering tooling. This electronic control supports repeatable output adjustments as operating demands change during production.
Its steel enclosure carries an IP20 protection rating, shielding users from live conductors while allowing airflow around internal components. The built-in auxiliary source provides 24 VDC at up to 2 A, so relays, sensors, and drive logic can be powered from the same chassis. The power stage accepts supply networks operating at 50 or 60 Hz, permitting installation in plants that follow either European or North American utility standards. Its climatic category is 3K3, indicating that the electronics tolerate the moderate humidity and other climatic conditions commonly encountered on production floors and test benches. Adequate cabinet spacing helps preserve cooling airflow around the enclosure during sustained operation.
Continuous operation is permitted between +10 °C and +55 °C, so heat sinks and ventilation must keep cabinet temperatures within this operating range. When de-energized, the unit can be stored at temperatures as low as -25 °C without damage to semiconductor junctions or electrolytic capacitors. It also tolerates shipment or warehouse temperatures as high as +70 °C, provided it remains powered off under those conditions. These climatic limits correspond to EN 60721-3-3 and support storage and operation under common factory climate controls. Supplemental temperature control may be necessary when the local conditions fall outside the permitted operating or storage ranges.
