Product Description:
The PSI6100.227-L1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat within the PSI Frequency Inverters series. The unit converts three-phase mains power into a regulated high-frequency output that drives induction heating, welding, or other industrial processes requiring precise energy delivery. By integrating the control electronics and power stage in one housing, the inverter simplifies cabinet layout and provides a ready-to-install solution for automated production cells. Its integrated design also reduces the number of separate components that must be accommodated in the control cabinet.
The power section accepts a three-phase input of 400 to 480 VAC at 50 or 60 Hz, allowing connection to common industrial power supplies. Internal components are kept within their thermal limits by forced-air cooling, so the unit does not require an external liquid-cooling circuit. The housing carries a protection rating of IP20, so it must be mounted in a suitable enclosure to limit dust exposure and prevent accidental contact. An integrated auxiliary supply delivers 24 VDC at up to 2 A, allowing it to power compatible sensors or fieldbus nodes without a separate power supply. The inverter exchanges status words and setpoints through a PROFIBUS timer interface, supporting synchronized operation with higher-level controllers. Cooling losses can reach 360 W, so the cabinet must provide adequate ventilation and a suitable path for exhausting warm air. Operation is classified under climatic category 3K3 of EN 60721-3-3, indicating the permitted humidity, temperature, and vibration conditions for installation in standard machine environments.
The permissible ambient temperature during operation ranges from +10 to +55 °C; operation outside this range may require derating or result in shutdown. During transportation or warehouse storage, the electronics can withstand temperatures from -25 to +70 °C without performance degradation. The unit has a total mass of approximately 20 kg, providing a rigid mounting base while remaining manageable during installation. Its mounting location should provide sufficient structural support and clearance for airflow around the cooling passages.
