Product Description:
The PSI6100.227-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase utility power into a controlled medium-frequency output that feeds induction heating generators and other resonance-driven loads used in automated manufacturing. An internal 24 VDC auxiliary supply and a PROFIBUS timing interface allow the unit to energize sensors or relays and receive deterministic commands without external power modules, streamlining cabinet layouts in industrial automation cells.
The inverter accepts a three-phase input of 400–480 VAC, which aligns with common factory power systems, and it synchronizes with line frequencies of 50 or 60 Hz. Control electronics and field devices are powered by the integrated bus, which provides 24 VDC at up to 2 A, so no separate DIN-rail power supply is needed. Thermal energy from the IGBT stack is removed through a water-cooled plate exchanger rather than forced air, permitting higher power density and minimizing cabinet temperature. Cooling losses are routed directly into the facility chiller circuit to maintain stable semiconductor junction temperatures during continuous operation.
Total heat transferred to the coolant is limited to 420 W, keeping enclosure temperatures predictable when the drive is mounted in a panel with an IP20 rating on the control side. The electronics remain within their operating limits throughout an ambient temperature range of +10 to +55 °C, matching the 3K3 climatic class for moderate industrial environments. During storage or transportation, the permitted temperature range extends from -25 °C to +70 °C, protecting spare units kept in unconditioned warehouses. The inverter weighs 25 kg, providing sufficient mass for stable installation while remaining compatible with common lifting aids used during panel assembly.
