Product Description:

The PSI65C0.710-W1 is a medium-frequency inverter built by Bosch Rexroth Indramat for the PSI Frequency Inverters series. The unit converts three-phase mains power into a regulated output suitable for induction heat generators, high-frequency spindle drives, and similar industrial loads that need precise current modulation at elevated carrier frequencies. By integrating the drive and a 24 V control supply in one housing, the inverter simplifies panel wiring while supplying auxiliary sensors and relays required by automated production cells.

The inverter connects to three-phase distribution lines rated at 400 to 480 VAC and maintains stable operation with either 50 or 60 Hz supplies. A built-in switched-mode section furnishes a regulated 24 VDC rail, and its maximum current capacity of 2 A eliminates the need for a separate logic power unit. Cooling is handled by a water-circulated plate that transfers process heat to plant chillers. The enclosure has an IP20 rating, so the device relies on the cabinet for protection from contaminants and moisture. Timing and synchronization cues reach the control board through an Ethernet timer channel that supports straightforward network integration.

Heat rejection at the maximum carrier frequency produces a cooling loss of 420 W, which must be included when sizing the water loop. The unit operates within an ambient temperature range of +10 to +55 °C, and it can be stored or transported between -25 and +70 °C without degrading internal components. Compliance with the 3K3 climatic category under EN 60721-3-3 indicates suitability for clean, temperature-controlled machine rooms. The unit has a mass of 25 kg, allowing it to be moved with suitable lifting equipment. The permitted operating range supports installation in industrial cabinets where surrounding temperatures remain controlled, while the broader storage range accommodates unpowered transportation and warehouse conditions.
