Product Description:
The PSI6100.750-L1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In automated machinery, it converts fixed three-phase mains power into a regulated medium-frequency output used to drive induction heating coils, resonant power supplies, or other loads that require controllable high-frequency energy. By integrating the power electronics and control hardware in one housing, the unit simplifies panel wiring and provides a compact drive element for production lines and laboratory test rigs. Its integrated design also reduces the number of separate control and power components needed within an installation.
The inverter connects to plant power through a three-phase input range of 400 to 480 VAC at 50/60 Hz, so it can operate on common industrial distribution systems without a transformer. An integrated, isolated converter produces 24 VDC at up to 2 A for sensors, relays, or small controllers, eliminating the need for a separate control supply. Cabinet air passes across the internal heat sinks because the inverter is air-cooled, and forced ventilation removes generated heat from the housing. The enclosure carries a protection rating of IP20, indicating protection against accidental finger contact with live parts while requiring installation inside a switchgear cabinet. Cycle coordination and diagnostic communication are handled through the designated Ethernet timer interface.
During operation, the electronics dissipate 360 W, which must be considered when sizing the cabinet airflow path. Reliable operation is maintained at ambient temperatures from +10 to +55 °C, while the permitted storage and transportation range is -25 to +70 °C. The climatic category is 3K3 according to EN 60721-3-3, allowing installation in locations with moderate humidity and limited dust. With a mass of approximately 20 kg, the inverter requires a mounting surface and fasteners capable of supporting its weight. Its rigid housing also helps protect internal components in environments subject to routine machine vibration.
