Product Description:
The PSI63C0.735-W1 medium-frequency inverter is produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. The unit converts fixed three-phase mains power into a controlled medium-frequency output used to drive induction heating coils, resonant power supplies, and other process equipment that requires programmable high-frequency energy. Within an automation cell, it connects to supervisory controls through an Ethernet timer interface, allowing coordinated heating or power delivery sequences that match production cycles and quality requirements. This communication link also supports precise timing between the inverter and other automated equipment in the production line.
It accepts a three-phase input of 400 to 480 VAC, so the inverter can be wired directly to common plant distribution networks without a step-up transformer. Internal rectification and modulation stages remain synchronized because the design accommodates supply frequencies of 50 or 60 Hz. The maximum thermal dissipation is 420 W, indicating the amount of heat that must be removed by the water channels routed through the baseplate. An integrated auxiliary supply delivers 24 VDC at up to 2 A, powering contactors, sensors, or small control relays in the same enclosure. This integrated supply eliminates the need for a separate low-voltage power module and reduces the number of components required inside the control cabinet.
The enclosure has a protection rating of IP20, so it prevents accidental contact with live parts but must be mounted inside a cabinet for protection from contaminants. Water-based heat exchange keeps semiconductor temperatures within an operating range of +10 to +55 °C. During nonoperational periods, the electronics remain stable within a storage temperature range of -25 to +70 °C. Conformance with climatic category 3K3 indicates that the unit can operate under typical production-floor humidity and vibration conditions. Despite the water jacket and integrated auxiliary supply, the inverter has a mass of 25 kg, which simplifies panel mounting and cabinet layout.
