Product Description:

The PSI63C0.179-W2 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. As a power electronics module, it converts high-voltage, three-phase mains power into a controlled medium-frequency output for induction heating, specialized spindle drives, and other processes that use adjustable high-frequency power. Integration into an automation cell allows precise regulation of the energy delivered to connected coils or motors. This controlled output helps maintain stable operation and reduces the mechanical stress associated with fixed-speed systems.

This model connects directly to industrial supply grids rated at 480 to 690 VAC and accepts base frequencies of 50 or 60 Hz, allowing operation on different industrial power networks without an external transformer. An internal auxiliary supply provides 24 VDC control power and can deliver up to 2 A for contactors, sensors, or small actuators, eliminating the need for a separate DIN-rail power module. The enclosure has a protection rating of IP20, so the inverter must be installed inside a suitable cabinet while remaining accessible for routine service. Its 3K3 climatic classification under EN 60721-3-3 supports operation in industrial settings with moderate humidity and dust when the unit is housed correctly.

Heat is removed through an integrated water-cooled channel in the baseplate, and the system must accommodate maximum cooling losses of 420 W. Adequate coolant flow and temperature control are required to keep the semiconductor junctions within their operating limits. The inverter operates at ambient temperatures from +10 to +55 °C, while permissible storage and transportation temperatures range from -25 °C to +70 °C. The unit has a mass of approximately 25 kg, which must be considered when selecting cabinet supports and mounting hardware. A 24 V timer interface is available for sequencing tasks that require delayed power-up or controlled shutdown of external devices.
