Product Description:

Bosch Rexroth Indramat builds the PSI63C0.765-W2 for its PSI Frequency Inverters series. This medium-frequency inverter connects to an industrial AC supply and generates controlled output power for induction heating, forging, and similar automated processes. Its regulated output supports applications that require precise energy delivery at elevated frequencies. The inverter communicates with a PLC through an Ethernet port, allowing real-time exchange of control commands and operating data.

The inverter produces a maximum cabinet heat loss of 140 W, so the enclosure ventilation system must remove this continuous thermal load. A water-cooled heat sink transfers heat to a process cooling loop through an M16 × 1.5 threaded connection. The hydraulic circuit has a pressure drop of 0.1 bar under the stated operating conditions. The mains nominal current is 110 A, and the permissible supply range is 480–690 VAC. During transient energization, current supplied to the transformer primary can reach 800 A. A TriCore CPU executes the control logic, while an Ethernet-based timer coordinates process sequencing. The enclosure measures 280 mm deep, 239 mm wide, and 448 mm high, allowing installation in standard switchgear frames.

On the secondary side, the converter can deliver up to 36 kA for processes that require high current at the work coil or connected load. The enclosure has a mass of 25 kg, which must be considered when selecting the mounting surface and supporting hardware. Continuous operation requires a minimum coolant flow of 4 L/min to keep the power semiconductors within their permitted temperature range. Cooling hoses should maintain this flow without causing the hydraulic pressure loss to rise beyond the allowable level. Field wiring requires conductors with a cross-sectional area of at least 35 mm² to carry the rated current without excessive heating. The Ethernet connection supports process triggers and diagnostic data through a single communication interface.
