Product Description:
Bosch Rexroth Indramat supplies the PSI64C0.766-W1 as part of the PSI Frequency Inverters series. This medium-frequency inverter converts fixed industrial mains power into a regulated output for inductive heating generators, high-frequency welders, and other automation applications that require stable intermediate frequencies. The unit integrates a power supply section and control electronics, allowing it to operate independently in a cabinet and communicate with higher-level controllers through Ethernet-based timing signals.
The inverter is designed for three-phase mains from 400 to 480 VAC at 50 or 60 Hz, providing flexibility across different industrial power grids. Heat generated by IGBT switching is removed through a water-cooled enclosure, allowing the unit to support high continuous current without relying on cabinet airflow. The housing has an IP20 protection rating, which guards live parts against finger contact while allowing access for wiring inside a closed panel. An integrated auxiliary supply provides a regulated output of 24 VDC at up to 2 A for contactors, sensors, or control relays, eliminating the need for a separate DIN-rail supply. Sequencing is governed by an internal Ethernet timer, which supports synchronization with PLC cycle times.
The cooling system must accommodate maximum losses of 420 W, which is used to size the heat-exchanger circuit that removes waste heat from the module. The electronics remain fully functional within an ambient temperature range of +10 to +55 °C. The permitted storage and transportation temperature range is -25 to +70 °C. These limits correspond to climatic category 3K3 under EN 60721-3-3, indicating suitability for controlled production areas with moderate humidity and limited dust. With a mass of approximately 25 kg, the chassis requires secure cabinet mounting appropriate for its weight. The water fittings are positioned to keep service loops short and support compact enclosure layouts.
