Product Description:
The PSI6200.256-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In production lines, it converts three-phase mains power into a controlled medium-frequency output that feeds induction heating generators, welding transformers, or similar equipment requiring adjustable power. Because the unit includes an internal 24 V auxiliary supply and a PROFIBUS-based fieldbus timer, it can occupy a central role inside larger automation cells. It coordinates with drives and PLCs while its power stage delivers the variable output required by rapid thermal or forming processes.
The inverter is designed for cabinet installation, and its enclosure carries a protection rating of IP20, requiring an electrical cabinet for complete protection against accidental contact. It connects to three-phase utility supplies between 400 and 480 VAC and synchronizes with networks operating at 50 or 60 Hz, allowing deployment in many industrial power systems without a step-up transformer. Control logic, sensors, and contactors can be powered directly from the integrated 24 V rail. This auxiliary source provides up to 2 A at 24 VDC, removing the need for an external switch-mode power supply and simplifying wiring within the cabinet.
To manage switching heat, the power stage is water-cooled, and its cooling circuit must dissipate up to 420 W of thermal losses under full load. Continuous operation is permitted across ambient temperatures from +10 to +55 °C, while the gasket materials and electronics remain stable down to -25 °C during storage and up to 70 °C during transport. The inverter meets climatic category 3K3 under EN 60721-3-3, so it tolerates moderate humidity and noncondensing dust when mounted in a protected cabinet. The chassis weighs 25 kg, allowing it to be positioned and secured without heavy lifting equipment when suitable handling practices are followed.
