Product Description:
The PSI6300.642-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat within the PSI Frequency Inverters series. The unit converts three-phase factory power into a regulated medium-frequency output for induction heaters, spindle motors, and other loads that require variable-frequency energy. By modulating voltage and current, it allows precise adjustment of process temperature or speed while maintaining efficient operation of connected equipment. Integrated control electronics support communication with machine controllers, making the inverter suitable for automated machining cells and forming lines where fast electromagnetic response is essential.
Electrical interfacing is centered on a three-phase supply of 400–480 VAC at 50 or 60 Hz. An internal auxiliary supply generates 24 VDC for sensors and control logic and can deliver a maximum of 2 A, eliminating the need for a separate 24-volt power rail. The power devices use a water-cooled heat exchanger that transfers thermal energy directly to a plant cooling loop, so cabinet airflow is not required for the inverter. The housing has an IP20 protection rating, providing protection against contact with hazardous internal parts when the unit is installed inside a closed control enclosure. Proper supply wiring, coolant connections, and enclosure placement are required to support stable operation within an industrial control system.
The cooling system must accommodate continuous heat losses of 420 W to prevent thermal derating during sustained operation. The permitted ambient temperature range during operation is +10 to +55 °C, while transport and storage are permitted from -25 to +70 °C when the unit is not operating. The device meets climatic category 3K3 according to EN 60721-3-3, indicating suitability for the moderate humidity and vibration commonly found in production facilities. A DeviceNet-compatible timer interface supports coordinated startup sequences and communication with related machine controls. The assembly weighs approximately 25 kg, which must be considered when selecting the cabinet structure, mounting surface, and lifting method used during installation.
