Product Description:
The Bosch Rexroth Indramat PSI63C0.181-L2 is a medium-frequency inverter in the PSI Frequency Inverters series. Designed for panel installation, it converts high-voltage utility power to the medium-frequency output required by induction heaters, test rigs, and other automated processes. In industrial automation, it delivers adjustable energy to the load while shielding upstream mains components from rapid load fluctuations. Its panel-mounted format allows the inverter to operate as part of a larger control system containing protection, switching, and process-control equipment.
The inverter accepts an input range of 480–690 VAC at 50/60 Hz, allowing the same device to operate with common North American or European industrial supplies without taps or transformers. An internal power module generates a stabilized control supply of 24 VDC and can provide up to 2 A. This onboard supply can energize compatible relays or field I/O without requiring a separate auxiliary transformer. The enclosure has an IP20 protection rating, which provides protection against accidental finger contact with live components but requires installation inside a suitable cabinet. Axial fans draw ambient air through the heat sink, and this air-cooled arrangement controls semiconductor temperatures without requiring a liquid cooling circuit.
Maximum cooling losses are rated at 360 W, which should be considered when calculating cabinet airflow or HVAC capacity. Continuous operation is permitted at ambient temperatures from +10 to +55 °C, while the storage range extends from -25 to +70 °C. The inverter has a mass of 21 kg, so firm mounting rails are required to support the unit and limit vibration. The unit complies with climatic class 3K3 under EN 60721-3-3, allowing operation in industrial atmospheres with moderate dust and noncondensing humidity. An integrated 24-volt timer circuit coordinates sequenced starts and stops for connected equipment. Adequate cabinet clearance must be maintained around the airflow path so that the axial fans can move cooling air across the heat sink without obstruction.
