Product Description:

The PSI63C0.782-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. As an adjustable power converter, it conditions three-phase mains energy into a controllable medium-frequency output that can drive induction heaters, high-speed spindles, or similar loads that benefit from precise power regulation. Its role in an automation cell is to supply stable high-frequency current while interfacing with modern control networks so that drive parameters remain synchronized with the overall machine program.

Thermal management is handled by a water-cooled circuit that transfers heat to an external exchanger instead of recirculating warm air inside the cabinet. The inverter accepts three-phase AC power on mains terminals U1, V1, and W1 and is compatible with TN, TT, or IT grounding systems. A voltage window of 400 – 480 VAC lets the unit operate on typical industrial distribution levels without tap changes, while its rectifier and DC link deliver energy to the medium-frequency stage. Installation supports vertical or backside mounting, which adds flexibility when cabinet depth is limited. For applications that require galvanic isolation, the outgoing energy can be routed through transformer terminals U2 and V2.

Control and diagnostic tasks are handled by a TriCore CPU. Command data moves through Ethernet, which also provides the timing reference used by the EtherNet timer function. The inverter generates a medium-frequency output up to 1 kHz, making it suitable for loads that require controlled high-frequency power. Its chassis carries an IP20 protection rating, and it may be mounted in an area rated IP54. This arrangement keeps the electronics in a clean area while the surrounding bay can tolerate dust or spray. Required clearances remain necessary at the mains and transformer terminals during service.
