Product Description:
The PSI64C0.660-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat as part of the PSI Frequency Inverters series. Intended for industrial automation, the unit converts three-phase utility power into a controlled medium-frequency output that drives induction heating coils, specialized spindle motors, or other equipment requiring variable high-frequency excitation. Its integrated design combines the power stage and control electronics to simplify cabinet layouts and reduce wiring when integrating the inverter into production machinery.
This inverter uses a water-cooled thermal management system, meaning heat is removed by a closed liquid circuit rather than by forced air, which permits dense packing in sealed cabinets. The housing carries a protection rating of IP20, so live parts are shielded against solid objects larger than 12 mm, but an additional enclosure is needed for wet areas. Input power is accepted from three-phase grids between 400–480 VAC at 50 or 60 Hz, allowing direct connection to plant mains without transformers. Under full load, the unit rejects up to 420 W of cooling losses that must be absorbed by the facility’s water circuit. Climatic category 3K3 per EN 60721-3-3 indicates suitability for machine rooms with moderate humidity and dust.
An integrated power supply module delivers a stabilized output of 24 VDC with a maximum current of 2 A, supplying sensors, contactors, or fieldbus nodes without an external source. The permissible operating temperature range is +10 to +55 °C, and the inverter can be stored from −25 °C to +70 °C without damage. Communication with controllers is handled through a DeviceNet timer interface that coordinates frequency ramps and status feedback over a single bus. The assembly weighs 25 kg, so a rigid mounting plate is required to resist vibration from connected machinery.
