Product Description:
The PSI6300.001-W1 medium-frequency inverter is manufactured by Bosch Rexroth Indramat and is part of the PSI Frequency Inverters series. It transforms fixed three-phase supply power into a controllable medium-frequency output. This output can drive induction heaters, weld generators, or similar energy-intensive loads where stable power at elevated frequencies improves process efficiency and quality.
The inverter accepts a supply range of 400–480 VAC, allowing it to connect directly to standard 400 V-class plant networks. Compatibility with 50 or 60 Hz mains supports operation on either common line frequency without requiring tap changes. Thermal management is handled by a water-cooled circuit that removes up to 420 W of internal heat, keeping semiconductor junctions within safe limits during continuous operation. Its enclosure carries an IP20 rating, so the unit must be installed inside a protected electrical cabinet that prevents access to live parts and limits exposure to dust. An integrated auxiliary converter supplies 24 V logic voltage and motor-contactor power for peripheral devices, eliminating the need for a separate low-voltage supply in the cabinet.
The auxiliary rail delivers 24 VDC at up to 2 A, providing power for contactors, sensors, or small actuators connected to the inverter’s control terminal strip. Continuous operation is permitted at ambient temperatures from +10 to +55 °C, while storage and transportation are permitted from -25 °C to +70 °C without degradation. Environmental classification 3K3 under EN 60721-3-3 indicates that the unit is intended for dry production areas with light dust and moderate temperature variation. During handling and mounting, its mass of 25 kg requires either two-person lifting or suitable mechanical assistance to move the unit safely.
