Product Description:
The PSI6100.001-L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. In an automation line, it converts three-phase utility power into a controllable medium-frequency output that drives induction heating coils, high-speed spindles, or other loads requiring regulated alternating current at elevated frequencies. By providing this intermediate power stage, the unit allows machine builders to match the electrical supply characteristics to the dynamic requirements of their processes.
The inverter is designed for utility inputs between 400 to 480 VAC and accepts line frequencies of 50/60 Hz, so it connects directly to common industrial power systems without step-up or phase conversion. An IP20 enclosure protects against incidental contact and is appropriate for mounting inside a closed cabinet. Thermal management relies on an air-cooled heat sink; during full-load operation, the cooling path must remove up to 360 W of heat generated by the power semiconductors and filtering components. Climatic class 3K3 under EN 60721-3-3 indicates suitability for moderate operating conditions in production facilities when humidity and other climatic influences remain within the permitted limits.
An integrated auxiliary supply provides the control electronics and external sensors with 24 VDC at up to 2 A, eliminating the need for a separate DIN-rail power module. Continuous operation is permitted when the ambient air remains between +10 to +55 °C; outside this range, output derating or additional cooling may be required. For transportation and spare-parts storage, the assembly withstands temperatures from -25 to +70 °C without degradation. The steel chassis and heat sink bring the total mass to approximately 20 kg, so the cabinet and mounting hardware must be able to support the installed load securely.
