Product Description:
The Bosch Rexroth Indramat PSI65C0.734-W1 belongs to the PSI Frequency Inverters series and is classified as a medium-frequency inverter for industrial automation. It converts three-phase mains power into a regulated medium-frequency source for induction heating, brazing, or welding equipment. A water-cooled design permits compact packaging, while high-speed switching supports the rapid energy modulation required by thermal processes. The unit is intended for mounting inside a control cabinet and supports diagnostic communication for integration with automated production cells. Its output is well suited to applications that need repeatable heat input across short and closely controlled process cycles.
During normal service, the inverter accepts a three-phase input of 400 – 480 VAC and carries a cabinet protection rating of IP20. An internal auxiliary rail feeds control boards with 24 VDC at up to 2 A. Heat generation is 100 W under standby cabinet load and 850 W when the current is at its peak, while the external exchanger must dissipate up to 4400 W from the power stack. A coolant flow of 10 l/min creates a 0.65 bar pressure drop through the channels, so the water circuit must be sized accordingly. Installation requires 100 mm of free space around the enclosure and placement in an IP54 environment. Integrated temperature monitoring automatically reduces current if thermal limits are approached, which helps protect the power section during extended operating periods.
The power stage can supply a primary current of 2400 A at a switching frequency of 1 kHz, enabling tight coupling with low-impedance work coils. Up to 256 individual programs are stored locally and can be triggered through the EtherNet timer interface for sequenced heating profiles. This allows the control system to switch between process routines without manual adjustment during normal operation. Metal-oxide-varistor overvoltage protection limits incoming spikes, and altitude capability extends to 2000 m without output derating. The protective functions and stored control routines support stable operation when line conditions and thermal demand change during automated cycles.
