Product Description:

The PSI64C0.710-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It converts three-phase utility power into a controllable output that feeds induction heaters, high-frequency welders, or other loads requiring stable medium-frequency energy. Within an automation cell, the inverter functions as the power stage while supervisory control arrives through an EtherNet timer interface, allowing precise coordination with motion axes, material-handling equipment, and process sensors.

The thermal design relies on a water-cooled heat exchanger, so cabinet airflow is not required and operating noise remains low. All electronics sit behind an IP20 housing, which prevents accidental contact but must be mounted inside a protected enclosure. The input section accepts three-phase mains between 400–480 VAC, and its rectifier synchronizes with 50 or 60 Hz power grids without adjustment. A secondary 24 V rail is generated internally. This regulated line is rated at 24 VDC and supports sensors, relays, or the fieldbus transceiver without requiring a separate power source for those connected components.

A maximum auxiliary supply current of 2 A is available on the 24 V rail, providing enough capacity for indicator lamps or small actuators that share the inverter panel. During continuous full-load operation, the coolant must remove up to 420 W of heat generated by the switching devices and transferred through the water jacket. Reliable operation is supported from +10 to +55 °C, aligning with the 3K3 climatic category for sheltered production areas. When the unit is stored or transported, it tolerates temperatures from -25 to +70 °C. The enclosure weighs 25 kg, so its cabinet slide or shelf must provide adequate structural support before the cooling hoses and bus connections are installed.
