Product Description:
The PSI63C0.727-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase mains power into a variable medium-frequency output that drives machine-tool spindles, induction heaters, or other processes requiring tightly controlled high-frequency power. The unit uses water cooling to remove heat from its switching stage, permitting cabinet installation without high airflow. In automated lines, the inverter acts as the power stage of a closed-loop spindle drive and accepts timer commands through its Ethernet interface for coordinated motion or process cycles.
Power enters the inverter at 400 to 480 VAC, a range that matches standard industrial low-voltage networks and eliminates the need for step-up transformers. It synchronizes with mains frequencies of 50 or 60 Hz, allowing the same unit to operate with either frequency. The control electronics are protected by an enclosure rated IP20; the inverter must therefore be installed inside an additional cabinet when exposure to dust or fluids is expected. An internal auxiliary supply delivers 24 VDC for sensors, relays, or drive controllers. This supply can provide up to 2 A, removing the need for an external logic power module.
The water circuit must dissipate a maximum cooling loss of 420 W to keep semiconductor temperatures within the 3K3 climatic category under EN 60721-3-3. During operation, the inverter can withstand ambient temperatures from +10 to +55 °C, which accommodates typical conditions inside industrial facilities. During storage or transportation, it tolerates ambient temperatures from -25 to +70 °C without degradation of capacitor life or sealing compounds. The mounting frame and heat exchanger assembly weigh 25 kg, so the supporting panel and mounting hardware must be suitable for the assembled load.
