Product Description:

The PSI63C0.620-L2 belongs to the PSI Frequency Inverters series manufactured by Bosch Rexroth Indramat. Classified as a medium-frequency inverter, it converts high-voltage three-phase mains power into a controlled output that permits speed or power modulation of induction equipment in automated production cells. Integrating the inverter between the plant supply network and driven loads provides electronic adjustment of process variables without mechanical gear changes, a common requirement in material-handling and forming systems.

This model accepts a supply range of 480 to 690 VAC at line frequencies of 50 or 60 Hz, allowing installation on common industrial feeders in Europe and North America. An internal auxiliary supply delivers 24 VDC and can provide a maximum current of 2 A for sensors, contactors, or fieldbus nodes, eliminating the need for an external 24-volt module inside the cabinet. Maximum cooling losses are 360 W, and the enclosure ventilation system must remove this heat to keep semiconductor junction temperatures within their operating limits. The inverter communicates timing and status through a DeviceNet timer interface, enabling integration into distributed control systems.

The unit has an IP20 protection rating, so it requires installation in a clean electrical room or closed panel. Heat is removed through an air-cooled system, and installation clearances must allow unrestricted airflow around the enclosure. Continuous operation is permitted at ambient temperatures from +10 to +55 °C, while storage or transportation is permitted at temperatures as low as -25 °C without damaging the electronics. The 3K3 climatic classification under EN 60721-3-3 permits operation in industrial locations where condensation is controlled and airborne contamination remains limited. The unit has a mass of 21 kg, which must be considered when selecting cabinet rails, mounting hardware, and appropriate handling equipment.
