Product Description:

The PSI64C0.333-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat and assigned to the PSI Frequency Inverters series. The unit takes utility-grade AC power and generates controlled medium-frequency power for induction processes, specialized spindles, or other equipment that cannot be fed directly from the mains. By integrating power conversion, monitoring, and fieldbus timing in one enclosure, the device supports compact cabinet layouts and coordinated motion or process sequences.

It accepts three-phase supply voltages from 400–480 VAC at 50 or 60 Hz, so it fits both European and North American plant grids without transformer adaptation. Thermal management is handled by a water-cooled plate that limits internal temperature rise. Under worst-case conditions, the cooling circuit must dissipate 420 W. The housing provides an IP20 protection level and complies with climatic category 3K3 of EN 60721-3-3, making it suitable for clean, temperature-controlled machine rooms. Command sequencing is coordinated through an INTERBUS timer interface that permits deterministic communication with compatible control systems.

The integrated auxiliary supply delivers 24 VDC at up to 2 A, powering sensors, relays, or drive electronics without an additional DC source. Continuous operation is permitted at ambient temperatures from +10 °C to +55 °C, while storage and transport are permitted between -25 °C and +70 °C. These temperature ranges allow the inverter to remain stored in an unconditioned facility before installation while providing a clearly controlled operating range after it is placed in service. With a mass of 25 kg, the inverter can be securely mounted near the water manifold, helping minimize cooling-hose length and pressure drop. Its cabinet location should also provide appropriate clearance for wiring, coolant connections, and ventilation around adjacent equipment.
