Product Description:
The PSI 6200.100W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. Designed to modulate the energy drawn from 400 to 480 V mains, it feeds induction heaters, melting furnaces, or other loads that need tightly controlled medium-frequency power. The device mounts inside a switch cabinet, sits between a dedicated step-down transformer and the load, and receives gating commands from a PLC or process controller through its V24/RS-232 serial line.
Its maintenance logic retains parameter tables with a Lithium AA 3.6 V battery, preventing data loss during power cuts. The power stage is rated for a continuous thermal current of 220 A, so the bus bars and semiconductor stack can deliver sustained output without exceeding junction limits. Control electronics run from a 24 VDC external supply, while an internal 24 V source provides 2.5 A for sensors or relays. Heat is removed through a water-cooled heat exchanger; coolant enters on the rear side, flows through brazed plates, and exits at the front. The mains input accepts 400–480 VAC, and cables up to 95 mm² may be landed on the dedicated mains and transformer terminals when the inverter is supplied by the PSG 3100.00 A or PSG 3200.00 A transformers.
During installation, the inverter requires a minimum clearance of 100 mm around the housing so that airflow near ancillary components and the coolant hoses is not obstructed. Hose adapters fasten to an M16×1.5 threaded port, providing a reliable seal for the water circuit. The enclosure carries an IP20 protection rating, so it must be placed inside a closed control cubicle to avoid accidental contact with live parts. Application data and parameter macros are stored in nonvolatile memory that holds up to 256 user-defined blocks, which can be loaded or edited through the 9-pin Cannon connector over the existing serial link without energizing the main bus.
