Product Description:

The Bosch Rexroth Indramat PSI6300.114-W1 is a medium-frequency power inverter in the PSI Frequency Inverters series. Within an automation cell, it converts a three-phase utility supply into a controlled medium-frequency output so that induction heaters, high-speed spindle motors, or similar loads can be regulated directly by the motion controller. By integrating the inverter with closed-loop drives, the manufacturer positions it as an intermediate power stage between the plant mains and application-specific resonant circuits, improving control of thermal or rotational processes.

Designed for European and North American utility grids, the input section accepts three-phase power at 400 to 480 VAC and operates at line frequencies of 50 or 60 Hz, enabling installation without external transformers. Heat generated by the IGBT bridge is removed through a water-cooled plate, and cooling losses are limited to 420 W, allowing the cabinet air conditioner to remain compact. The electronics are protected to IP20, so the unit must be mounted inside an enclosure and is protected against finger contact with hazardous internal parts. The unit follows climatic category 3K3 under EN 60721-3-3, confirming suitability for machine rooms with moderate humidity and minimal conductive debris. A built-in 24 V timer circuit coordinates switching sequences with other drives, eliminating the need for an external relay module.

Low-voltage services are supplied by the internal power module. This module delivers 24 VDC at up to 2 A for contactors, sensors, or fieldbus couplers. During operation, the inverter maintains full power from +10 to +55 °C, supporting use across a broad range of industrial cabinet temperatures. It withstands storage temperatures from -25 to +70 °C, which accommodates powered-down equipment and inventory held in unconditioned facilities. The unit has a transport weight of approximately 25 kg, so suitable lifting equipment should be used during handling and rack installation.
