Product Description:
The PSI6100.630-W2 medium-frequency inverter is produced by Bosch Rexroth Indramat and belongs to the PSI Frequency Inverters series. As a power conversion module, it supplies variable medium-frequency output to induction heating coils, high-speed spindle drives, and other equipment that uses programmable current and voltage profiles. Within an automation cell, the inverter connects the plant mains to the controlled load and coordinates energy delivery, while its integrated auxiliary supply powers sensors and control electronics. This arrangement reduces the need for separate power conversion and low-voltage supply components inside the control cabinet.
Its three-phase input section accepts line voltages from 480 to 690 VAC at mains frequencies of 50 or 60 Hz, allowing installation on standard high-voltage distribution networks. An internal 24 V auxiliary rail provides 24 VDC with a maximum output current of 2 A, so external relays and field devices can be powered without an additional supply. During operation, the water-cooled heat exchanger removes up to 420 W of power losses, helping keep semiconductor junctions within their safe temperature range and reducing heat accumulation in the cabinet. DeviceNet timing support enables coordinated startup with higher-level controllers. The water-cooling arrangement transfers heat away from sensitive power electronics without relying entirely on cabinet airflow.
The enclosure has an ingress protection rating of IP20, so the inverter must be mounted inside a switchgear cabinet that protects it from dust and dripping water. The permitted ambient temperature range of +10 to +55 °C supports continuous operation under typical machine-room conditions, while transportation and storage temperatures may range from -25 °C to +70 °C. Compliance with climatic class 3K3 under EN 60721-3-3 indicates suitability for moderate climatic conditions commonly found in production facilities. The unit weighs 25 kg, which limits the structural load placed on the mounting panel. Its enclosed design also helps prevent accidental contact with internal electrical components when it is correctly installed in a suitable cabinet.
