Product Description:

The PSI63C0.232-W2 medium-frequency inverter is produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts high-voltage industrial mains power into a regulated medium-frequency output that supplies induction heating stations, specialized drives, or other process actuators within automated production cells and test rigs. By providing programmable frequency control, the device enables tighter thermal profiles and coordinated energy management compared with fixed-speed operation.

Incoming power can range from 480 to 690 VAC, so the inverter connects directly to high-voltage plant distribution boards without an intermediate transformer. It synchronizes with utility grids operating at 50 or 60 Hz, allowing deployment in both European and North American facilities. Control electronics are fed by an integrated auxiliary supply that delivers 24 VDC at up to 2 A; this rail powers contactors, sensors, or fieldbus gateways mounted nearby. The housing carries an IP20 rating, providing protection against accidental contact when the unit is installed inside a cabinet. Compliance with climatic class 3K3 under EN 60721-3-3 indicates that the unit tolerates moderate humidity and noncondensing conditions typical of machine halls. Configuration and sequencing are handled through a PROFIBUS timer channel, providing deterministic communication with supervisory PLCs.

A liquid circuit routed through the heat sink provides water cooling as the primary method of removing heat. Under continuous full-load conditions, the heat exchanger must dissipate up to 420 W of thermal loss, so its flow rate and inlet temperature should be selected accordingly. Permissible ambient temperatures during operation range from +10 to +55 °C. The electronics may be stored or transported at temperatures from -25 to +70 °C without performance degradation. The enclosure weighs 25 kg, allowing it to be mounted on a suitable panel slide or installed within an equipment rack. Adequate structural support and access to the liquid connections are required when positioning the inverter inside a cabinet.
