Product Description:
The PSI63C0.725-W2 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In automated plants, this unit converts high-voltage three-phase mains power into a controllable medium-frequency output that drives induction coils, heat-treating equipment, or other loads that require adjustable kilohertz power. The inverter integrates an auxiliary supply for sensors and contactors, allowing low-level control circuits to receive power from the same enclosure without requiring an external supply. This arrangement reduces the number of separate power components needed within the control cabinet.
This model removes switching heat through a water-cooled plate, limiting thermal stress with a maximum heat dissipation of 420 W. It accepts line voltages between 480–690 VAC and synchronizes automatically with 50/60 Hz grids, providing flexibility across different industrial power systems. An internal auxiliary converter delivers a regulated 24 VDC rail that keeps the control electronics active when the power stage is disabled. The climatic rating of 3K3 under EN 60721-3-3 indicates suitability for clean, temperature-controlled machine halls. EtherNet timing support enables time-critical commands and diagnostic data to travel over standard industrial networks without requiring a separate communication path.
The enclosure has an IP20 degree of protection, so it must be installed inside a cabinet while providing protection against accidental finger contact with internal components. The auxiliary supply can provide up to 2 A, which is suitable for small relays, sensors, and proximity switches connected to the control circuit. Reliable operation is supported at ambient temperatures from +10 to +55 °C, while noncondensing storage is permitted from -25 °C to +70 °C. At approximately 25 kg, the inverter requires a mounting surface and fasteners capable of supporting its installed mass. Adequate cabinet clearance must also be provided for electrical connections, coolant lines, and access to the inverter’s control interfaces.
