Product Description:
The PSI6300.325-L1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. This device converts fixed three-phase mains power into controllable medium-frequency power for induction heating coils, welding equipment, and similar loads in automated production lines. A dedicated INTERBUS control interface allows a PLC to trigger the inverter precisely and coordinate its operation with other machine functions. The cabinet-mount housing supports integration into industrial electrical enclosures.
The inverter accepts a supply of 400–480 VAC, allowing direct connection to common low-voltage industrial networks without step-up transformers. Its compatible line frequency of 50 or 60 Hz supports operation with either standard supply frequency. An auxiliary bus supplies the internal electronics and sensors with 24 VDC at a maximum of 2 A, reducing the need for a separate control power module and simplifying wiring. The metal enclosure has an IP20 rating, which protects against accidental contact with the terminals when the unit is installed inside a closed cabinet. The surrounding cabinet must provide the necessary protection from dust and liquids. An INTERBUS timer channel coordinates frequency ramps with upstream motion or temperature control loops, keeping the inverter output synchronized with the machine cycle.
Thermal management uses an air-cooled design that expels heat through internal fans. During continuous full-load operation, the inverter produces up to 360 W of heat that must be removed from the cabinet. The unit meets the 3K3 climatic class under EN 60721-3-3 and can operate at temperatures from +10 °C to +55 °C. Its permitted storage and transportation temperature range extends from -25 °C to +70 °C. A weight of 20 kg supports rigid panel mounting in locations where vibration is limited. Adequate cabinet ventilation and suitable mounting clearances are required to maintain airflow through the inverter and prevent excessive internal temperatures during sustained operation.
