Product Description:
The Bosch Rexroth Indramat PSI62C0.632-W1 belongs to the PSI Frequency Inverters series and functions as a medium-frequency inverter within automated production lines. It converts fixed-frequency mains power into regulated high-frequency current that excites induction coils or high-frequency transformers used for welding, brazing, or surface treatment tasks. The housing and interface arrangement allow the inverter to be mounted near the work cell, while the associated controller supervises its operation through the available fieldbus architecture.
The inverter accepts a supply range of 400–480 VAC, and copper conductors up to 95 mm² can be terminated at the mains connections to carry the required current. Thermal energy from the power stage is removed through a water-cooled plate, eliminating the need for cabinet airflow around the heat sink. Communication with the supervisory PLC is handled through a DeviceNet slave interface, while a DeviceNet timer resource synchronizes internal sequences with field commands. The internal generator operates at 1000 Hz, providing the medium-frequency output required for induction applications. One KSR input monitors keying signals. A single MCB trip output reports circuit-breaker status to upstream safety circuits.
Local input and output handling includes 64 serial inputs and 64 serial outputs for exchanging a large number of discrete signals. The unit also provides eight parallel 24 V inputs, eight parallel 24 V outputs, and four dedicated tip channels that support secondary feedback measurements. Process pressure is monitored through binary feedback and delivered to the controller through an analog pressure output. Stop commands can be switched directly by contacts rated at 24 VDC / 3 A, providing rapid energy isolation when a stop signal is issued. The transformer connection accommodates the required power conductors, and one transformer temperature input monitors winding temperature increases during operation.
