Product Description:
The PSI64C0.357-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. Designed for industrial automation, it converts three-phase mains power into a controllable medium-frequency output that can drive induction heating coils, high-frequency spindles, or similar loads. The unit integrates power conversion, an auxiliary supply, and fieldbus timing in a single chassis, allowing compact installation in water-cooled thermal or motion systems.
Thermal management is handled by a water-cooled plate, which permits continuous operation without adding substantial heat to the control cabinet. The electrical input accepts 400–480 VAC from three-phase lines operating at 50 or 60 Hz, allowing use with both European and North American power grids. An integrated supply generates 24 VDC for drive logic, contactors, and external sensors, eliminating the need for a separate DIN-rail supply. The enclosure has an IP20 protection rating, which provides protection against accidental contact with live components but requires installation inside a suitable cabinet. INTERBUS timer hardware coordinates frequency-reference updates with the plant network, keeping the inverter output synchronized with motion or heating profiles.
The auxiliary source can deliver a maximum current of 2 A, which is sufficient to power small relays or encoder interfaces alongside the inverter. During heavy-duty operation, the converter transfers up to 420 W of heat to the coolant circuit, and this thermal load must be considered when sizing the cooling system. Reliable operation is supported within an ambient temperature range of +10 to +55 °C, while storage or transportation is permitted at temperatures as low as −25 °C. Compliance with climate class 3K3 under EN 60721-3-3 indicates resistance to humidity and airborne contaminants commonly found in production facilities. Despite its integrated water channels, the assembly weighs 25 kg, allowing it to be installed in an industrial control cabinet with appropriate lifting equipment.
