Product Description:
The PSI63C0.201-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts standard three-phase plant power into a controlled medium-frequency output used to drive induction heaters, high-frequency spindles, and similar loads in automated production lines. By integrating power electronics, a cooling interface, and an auxiliary control supply in one enclosure, the unit simplifies panel design and supports continuous operation in demanding industrial settings.
Heat is removed by a water-cooled plate that keeps semiconductor temperatures within operating limits while preventing heat from entering the cabinet air. The housing has an IP20 protection rating, so live parts remain shielded from accidental contact when the inverter is installed inside a closed panel. An internal auxiliary supply delivers 24 VDC at a maximum current of 2 A, providing power for relays, sensors, or small actuators without an external supply. The input section accepts grid frequencies of 50 or 60 Hz across a voltage range of 400–480 VAC, allowing direct connection to common European or North American power systems. During operation, the inverter produces up to 420 W of heat loss that must be removed by the external water circuit. Continuous operation is permitted at ambient temperatures from +10 to +55 °C. The assembled device weighs 25 kg, which should be considered when selecting mounting hardware and supporting cabinet structures.
The design meets climatic class 3K3 under EN 60721-3-3, so it tolerates moderate humidity and noncondensing dust levels found in standard machine halls. For communication sequencing, a PROFIBUS-based timer coordinates frequency adjustments with higher-level controllers, reducing the need for proprietary cabling. When the power is off, the unit can withstand storage and transportation temperatures from -25 to +70 °C without degradation of electronic components or sealing surfaces. These operating conditions should be considered when selecting the installation location, cooling equipment, and transportation method. Adequate cabinet clearance also allows access to the electrical connections and water-cooling interface during routine inspection. Proper handling helps prevent excessive mechanical stress on the enclosure before the inverter is secured in its operating position.
