Product Description:

The PSI64C0.232-W1 is a medium frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. As a power conversion stage, it supplies controlled high-frequency current to induction heating, forging, or melting equipment in automated production lines. The unit links to plant PLCs by PROFIBUS and relies on an integrated TriCore processor to execute current regulation algorithms in real time.

In normal operation, the inverter is connected to a three-phase supply of 400-480 VAC, drawing a mains nominal current of 220 A. Inside the water-cooled cabinet, a TriCore CPU supervises the IGBT bridge while PROFIBUS handles both I/O traffic and the built-in timer function. Primary busbars can accept up to 1600 A peak, and the resonant output circuit is rated for a secondary current of 54 kA to drive large induction coils. Basic cabinet heat dissipation is limited to 69 W, allowing compact enclosure sizing. The 95 mm² connection cross-section accommodates the high continuous current. Physical dimensions of 653 mm in height, 288 mm in width, and 280 mm in depth simplify integration into standard machine frames.

During heavy load cycles, the cooling system must remove up to 700 W of inverter and transformer losses, and it does so with a minimum water flow of 4 l/min. Hydraulic resistance across the internal channels produces only 0.6 bar of pressure drop, keeping pump demand relatively low. When the drive reaches maximum induction duty, the cabinet loss value rises to 210 W, still within the capability of the water circuit. The water-cooled design maintains semiconductor temperature without additional air conditioning, supporting stable performance at full primary and secondary current ratings. The unit has a total mass of 40 kg, which should be considered when planning cabinet support and handling.
