Product Description:
The PSI65C0.782-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. As a dedicated power converter, it transforms three-phase utility power into a regulated medium-frequency output used to drive induction coils, hardening furnaces, or similar equipment within automated cells. By delivering controlled energy at higher switching frequencies, it allows precise thermal profiles and shorter cycle times while remaining compatible with standard plant power networks.
The unit accepts a three-phase factory supply of 400–480 VAC at 50 or 60 Hz, and an internal rectifier and chopper stage condition the incoming power to produce the required output. Heat generated by the power stack is removed through a water-cooled plate, so installation requires a closed-loop coolant circuit instead of cabinet airflow. The enclosure has an IP20 rating, protecting live parts against contact with solid objects larger than 12.5 mm when the unit is mounted inside a control cabinet. Under maximum load, the inverter transfers up to 420 W of residual heat to the coolant, which must be considered when selecting the heat exchanger and pump capacity. The unit meets climatic class 3K3 under EN 60721-3-3, making it suitable for industrial buildings with moderate humidity and minimal dust.
The control electronics include an auxiliary supply that provides 24 VDC with a maximum current of 2 A for sensors, relays, or fieldbus gateways, eliminating the need for a separate supply module. The acceptable ambient operating temperature ranges from +10 to +55 °C, while storage and transportation are permitted between −25 °C and +70 °C without performance degradation. Cyclic timing is coordinated through an Ethernet-based timer interface, simplifying synchronization with PLC sequences and other automated processes. The assembly has a mass of 25 kg, so panel hinges or slide rails must be rated to support this load. Adequate mounting support also helps keep the inverter secure during normal machine vibration and cabinet servicing.
