Product Description:
The PSI64C0.201-W1 belongs to the PSI Frequency Inverters series produced by Bosch Rexroth Indramat. It is a cabinet-mounted drive that converts fixed mains power into controlled medium-frequency output for induction heating, welding, or similar automation tasks that need precise energy dosing. By combining a TriCore-based controller with a PROFIBUS communication link, the unit coordinates power delivery with upper-level PLCs and maintains repeatable process parameters. This control structure supports stable timing and current delivery during processes that depend on closely managed heat input.
The inverter connects to three-phase supplies between 400 – 480 VAC and draws up to 220 A of nominal mains current through 95 mm² conductors. Internal losses are split between a 69 W basic cabinet level and 210 W at maximum load, so enclosure ventilation must account for that heat if the primary water-cooled circuit is unavailable. The housing is rated IP20, allowing installation inside a switchgear room while preventing accidental contact with live parts. The TriCore CPU executes modulation and protective routines, while the PROFIBUS I/O interface exchanges setpoints, status words, and diagnostic data. A matching PROFIBUS timer channel synchronizes trigger events with the plant clock.
During short bursts, the power stage can accept 1600 A of primary current and deliver up to 54 kA (PSG 3100) on the secondary side, enabling rapid energy transfer to a work coil. The water jacket must remove as much as 700 W of thermal loss, which it does when at least 4 l/min flow is provided; this produces a pressure drop of 0.6 bar across the exchanger. Overall dimensions of 653 mm in height, 288 mm in width, and 280 mm in depth allow stacking in 600 mm-wide racks. This operating range supports fast heat buildup in applications that use brief, high-energy pulses.
