Product Description:
The PSI6500.190-W1 is classified as a medium-frequency inverter manufactured by Bosch Rexroth Indramat within the PSI Frequency Inverters series. Designed for automation cells, it converts factory mains power into a regulated high-frequency output that feeds induction heaters, high-speed spindles, or test benches that cannot be driven directly from line power. The unit operates as a dedicated power stage that follows setpoints from a PLC or motion controller while its internal logic keeps switching devices within safe limits. An integrated control supply and grouped terminals allow logic and load conductors to be routed through one enclosure, reducing wiring complexity.
The inverter connects to three-phase networks rated at 400–480 VAC and tolerates line frequencies of 50 or 60 Hz, so external transformers are not required in most plants. A self-contained supply section delivers 24 VDC for sensors, relays, and fieldbus electronics and can provide up to 2 A continuously, eliminating the need for a separate DIN-rail converter. The electronics are housed in an enclosure with a protection rating of IP20. The assembly must therefore be mounted inside a closed control cabinet, but its enclosure protects against accidental contact with internal components. These electrical and housing parameters establish the minimum installation conditions for reliable medium-frequency conversion.
Water circulation removes up to 420 W of switching losses, helping keep semiconductor junction temperatures stable across an ambient range of +10 to +55 °C. During transportation or warehouse storage, the unit withstands temperatures from -25 to +70 °C and meets climatic category 3K3 under EN 60721-3-3. A 24 V timer circuit built into the control board supports the staggered startup of contactors or cooling pumps. With a mass of 25 kg, the inverter can be mounted on suitable swing panels or slide rails without exceeding the load limits of compatible enclosure hardware.
