Product Description:
Bosch Rexroth Indramat manufactures the PSI63C0.732-W1 within its PSI Frequency Inverters series. Classified as a medium-frequency inverter, the unit converts three-phase line power into a variable medium-frequency output for controlled motor or process power in industrial automation. By inserting this electronic stage between the supply network and the load, operators gain precise speed or power adjustment without mechanical intervention. The design also incorporates an internal 24 V auxiliary supply, allowing nearby sensors and relays to draw control power directly from the inverter while keeping cabinet wiring compact.
The electrical interface is sized for factory networks that provide a line voltage of 400 to 480 VAC at 50 or 60 Hz. Water-cooled heat exchangers remove up to 420 W of cooling losses so full output can be maintained even in sealed enclosures. The unit has an IP20 protection rating, which guards components against finger contact while leaving airflow around the electronics unrestricted. The integrated power supply furnishes 24 VDC at up to 2 A. This current is suitable for gate drives, contactors, or small PLC I/O modules mounted nearby. A water loop rather than forced air stabilizes internal temperatures, reduces acoustic noise, and supports higher power density in crowded automation panels.
The inverter meets climatic category 3K3, making it suitable for production areas where airborne dust is low and condensation is absent. It operates from +10 to +55 °C and can be stored or transported between -25 and +70 °C without damage to the power semiconductors. Timing and diagnostic functions are accessed through the built-in Ethernet communication port, simplifying integration with supervisory controllers. With a mass of 25 kg, the unit can be mounted on standard DIN shelves or slide rails without requiring specialized lifting equipment.
