Product Description:
The PSI63C0.762-L2 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In induction-heating stations and special machine tools, the unit converts three-phase mains power into a controlled high-frequency output that drives resonant transformer circuits and work coils. This role places the inverter between the plant supply and the load, where it meters energy, executes Ethernet-based timing commands, and exchanges 208 input bits and 160 output bits with a Profinet controller.
The power stage operates at an output carrier frequency of 1000 Hz while accepting utility voltages from 480 to 690 VAC at 50 or 60 Hz. Line current reaches 110 A under nominal loading, and cabinet heat dissipation at rated output is held to 200 W. The housing carries a protection rating of IP20, so it must be installed inside an electrical enclosure. Air-cooled channels remove thermal losses, while connection terminals accommodate conductors ranging from 35 mm² to 50 mm² to keep temperature rise within limits. Internal electronics draw 2 A from the integrated 24 V service rail, and climatic classification 3K3 indicates suitability for workshops that remain dry but experience moderate dust and vibration. Basic switch-cabinet losses are 100 W, and auxiliary blowers limit maximum cooling losses to 420 W. A secondary cooling-loss value of 360 W applies when the drive operates below peak power.
Primary-side surge events are managed by a bus that can momentarily accept 800 A. Downstream, the matching transformer can deliver up to 36 kA to the workpiece circuit. Control boards, sensors, and contactors are fed directly by the inverter’s auxiliary supply at 24 VDC. The overall mass is approximately 21 kg, which allows panel mounting without additional supports. Operation is permitted between +10 °C and +55 °C, while storage is possible at temperatures as low as -25 °C. If liquid intercooling is added, a water flow rate of 4 liters per minute creates a pressure drop of only 0.1 bar through the heat exchanger. Mains-frequency synchronization, an Ethernet timer, and Profinet I/O support closed-loop control within automated production cells.
