Product Description:

The PSI6300.329-L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat and supplied under the PSI Frequency Inverters series. The device converts three-phase utility power into regulated medium-frequency output for induction heating or specialized drive axes in automated machinery. By integrating control logic, gating circuits, and an internal auxiliary supply within a single enclosure, it provides a compact interface between plant mains and loads that require precisely modulated energy at frequencies beyond the standard grid.

It connects to a three-phase supply rated at 400–480 VAC and accepts line frequencies of 50/60 Hz, allowing installation in plants that follow either European or North American power grids. Thermal management relies on an air-cooled channel that releases up to 360 W of heat, so external cabinet ventilation must accommodate that loss. The housing carries a protection level of IP20, which shields internal assemblies from fingers and solid objects larger than 12 mm but does not seal against moisture. Bosch Rexroth Indramat assigns the climatic category 3K3 per EN 60721-3-3, indicating that the inverter should operate in production areas free of condensation and airborne corrosive substances.

An integrated auxiliary supply delivers 24 VDC at up to 2 A, powering contactors, sensors, or fieldbus modules without an additional converter. Control coordination with higher-level equipment is handled through the INTERBUS timer interface, enabling deterministic communication for sequence triggers and diagnostic feedback. Reliable operation is maintained at ambient temperatures from +10 to +55 °C, and the inverter can be stored or transported at temperatures between −25 and +70 °C without damage. The installation mass is approximately 20 kg, which allows secure panel mounting while providing adequate internal space for the core and heat sink.
