Product Description:

The PSI63C0.732-L2 inverter is produced by Bosch Rexroth Indramat and belongs to the PSI Frequency Inverters series. As a medium-frequency inverter, it converts three-phase mains power into a regulated high-frequency output for induction heating, forging, or other industrial automation tasks that require flexible power control. It is designed for cabinet installation where Ethernet-based supervision ties its power electronics to higher-level machine controllers. Its architecture combines switching hardware, digital timing, and field wiring into one package.

Its regulation loop updates every 1 ms, allowing tight phase and amplitude control while it switches at an internal carrier of 1000 Hz. The power section tolerates input lines from 480 – 690 VAC, drawing a steady 110 A at rated load. A TriCore CPU coordinates gate drives, monitors analog feedback, and communicates through an RJ45 connector on the built-in Ethernet I/O port, and cable runs up to 100 m are accepted without repeaters. Air cooling removes the baseline 100 W of heat generated by semiconductors and magnetics inside the cabinet. The enclosure carries an IP20 degree of protection, so live parts are guarded against accidental contact while remaining accessible to the airflow required by the cooling method. The Ethernet timer provides precise scheduling for cycle-critical tasks.

For peak demand, the inverter supports a primary current of 800 A, and the downstream circuit can see secondary pulses up to 36 kA for short intervals. Configuration memory holds 256 individual programs, so process settings can be recalled without external tools. Digital status lines operate from a 24 VDC logic supply, and the output stage can source up to 2 A to drive relays or indicator modules. When the output is fully utilized, the cabinet’s thermal load rises to 200 W, so ventilation must be sized for this condition. No water circuit is needed because the product uses fan ventilation instead of liquid cooling.
