Product Description:

The PSI63C0.710-W2 is a medium-frequency inverter engineered by Bosch Rexroth Indramat for the PSI Frequency Inverters series. Acting as the power interface between a three-phase mains line and an induction load, the unit converts high-voltage supply energy into a controllable medium-frequency output used for coordinated automated operations. Its enclosure combines power electronics, digital control, and water-cooling hardware so the module can be mounted as a single assembly with connected services and synchronized current delivery. This arrangement suits process equipment that requires repeatable power control during automated cycles.

Its input stage accepts 480-690 VAC and draws a steady 110 A when delivering rated power. A TriCore processor executes modulation algorithms in real time, while Ethernet cabling carries I/O data to higher-level PLCs and supervisory systems. The controller electronics are supported by a 24 VDC logic rail, and an internal 2 A power supply is available for sensors or contactors. An Ethernet-based timer coordinates firing sequences without external relays, and the mains connection area accommodates conductors from 35 mm² up to 50 mm² so wiring can be secured without crowding the terminals.

The inverter is water cooled, accepting its coolant through an M16×1.5 coupling; a minimum flow of 4 l/min limits semiconductor temperature rise, and the circuit shows only 0.1 bar pressure drop at that rate. During fast energy bursts, the power stage can source 800 A on the primary side and, when paired with a PSG 3100 transformer, deliver 36 kA on the secondary. Physical dimensions of 239 mm wide, 448 mm high, and 280 mm deep allow placement inside standard cabinets without excessive footprint. The housing layout also supports orderly routing for both coolant lines and heavy power conductors in compact installations.
