Product Description:
The PSI6300.228-L2 medium-frequency inverter is produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It converts high-voltage three-phase power into a controllable medium-frequency output for induction heaters, high-speed spindle motors, and similar loads in automated production lines. The device is intended for panel installation alongside drive controllers and PLC hardware. Its compact arrangement allows the power conversion stage to be placed near the associated control equipment while remaining enclosed within a suitable industrial cabinet.
For electrical integration, the inverter accepts a line supply of 480–690 VAC at 50 or 60 Hz. An internal input filter supports electrical compatibility, while the IP20 enclosure protects against accidental contact with hazardous internal parts. The surrounding cabinet must provide suitable protection and the required clearances for the high-voltage terminals. The integrated auxiliary supply provides 24 VDC control power at up to 2 A, allowing it to power compatible contactors, sensors, or control circuits. Forced air drawn through the heat sink removes switching heat and supports continuous operation under load. The design complies with climatic class 3K3, allowing operation in indoor locations with moderate temperature changes and limited condensation. PROFIBUS communication coordinates start, stop, and frequency-reference data with a higher-level controller.
Heat dissipation can reach 360 W, so the cabinet ventilation system must maintain adequate airflow around the inverter. Continuous operation is permitted within an ambient temperature range of +10 to +55 °C. When the unit is not operating, it may be stored at temperatures from -25 to +70 °C, provided that the surrounding conditions remain suitable for industrial electronic equipment. With a mass of approximately 21 kg, the chassis can be mounted on a suitable standard backplate without additional bracing. Clearance should be maintained around the fan inlets and exhaust path to prevent restricted airflow. The mounting surface must also support the unit securely and allow access to its power, control, and communication connections.
