Product Description:
The PSI62C0.747-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. The unit converts fixed three-phase power into adjustable medium-frequency output that drives induction heaters, specialized spindle motors, or other high-frequency loads in automated production cells. By combining control, protection, and an auxiliary 24 V supply, the inverter provides a compact power stage for machinery where cabinet space and thermal management are constrained. Its integrated design reduces the number of separate power and control components required within the enclosure.
The power section accepts a three-phase input within a 400 to 480 VAC range and synchronizes with utility grids operating at 50 or 60 Hz, eliminating the need for external transformers on most European or North American lines. Thermal energy generated by the semiconductor bridge is extracted through a water-cooled heat exchanger, limiting internal temperature rise while accommodating maximum cooling losses of 420 W. The chassis provides IP20 protection, so it must be installed inside a control enclosure to prevent direct contact with internal components. An integrated logic supply provides a maximum current of 2 A from its onboard regulator, allowing it to power sensors or field I/O without an additional supply module. Cooling-loop connections should be routed so that water can circulate without restricting nearby wiring or obstructing access to the inverter.
The auxiliary regulator maintains a stable output of 24 VDC, providing control power even when the high-power stage is offline. Reliable operation is permitted at ambient temperatures from +10 to +55 °C, and the unit meets climatic class 3K3 under EN 60721-3-3 for use in low-condensation industrial facilities. When the machine is idle or the inverter is being transported, its internal components can withstand storage temperatures from -25 °C to +70 °C without degradation. The inverter weighs approximately 25 kg, which should be considered when selecting panel supports and routing the cooling lines. Time-critical coordination with supervisory controllers is handled through the built-in EtherNet timer interface. This interface supports synchronized control activity between the inverter and the surrounding automation system.
