Product Description:

The PSI63C0.132-L2 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. In automated heating, forging, and surface-treatment stations, it converts incoming three-phase power into a regulated medium-frequency signal that drives resonant tanks or induction coils. Installed inside a machine cabinet, it forms the power interface between the plant mains and the workpiece, allowing precise energy dosing and rapid cycle repeats in industrial production lines.

Electrically, the inverter accepts a supply window of 480 – 690 VAC and draws a nominal line current of 110 A; these values set upstream fusing and feeder sizing. For short duty bursts, the primary circuit can pass 800 A, while the associated PSG 3100 secondary path can withstand peaks of 36 kA, supporting high-impact heat pulses without current limiting. Baseline cabinet dissipation is 100 W, which provides an initial value for airflow planning. Cooling is air based, and thermal management is supervised by a TriCore CPU that also orchestrates gating patterns. Command and status bits are exchanged through a discrete 24 V I/O interface, and a 24 V timer module enables synchronized power windows with external motion or material-handling controllers.

When the inverter runs at continuous maximum output, cabinet losses rise to 200 W and overall cooling demand can reach 420 W, so a minimum installation clearance of 100 mm must be maintained to keep the flow path unobstructed. Power and load conductors terminate on clamps rated up to 50 mm², while applications with lower current density may use cables down to the specified 35 mm² minimum. The enclosure stands 463 mm tall, allowing placement in standard 600 mm panels with room for ducting above. That cabinet height also leaves space for cable bends and ventilation routing inside enclosed panels.
