Product Description:
The PSI65C0.132-W1 medium-frequency inverter is manufactured by Bosch Rexroth Indramat and belongs to the PSI Frequency Inverters series. It serves as the power conversion stage between the plant’s three-phase supply and the medium-frequency bus used by automated machinery, enabling precise current and voltage modulation for process equipment on the factory floor. Its design couples a high-capacity output section with integrated water cooling, making the unit suitable for high-current tasks that require a compact installation footprint within control cabinets.
The inverter accepts an input of 400–480 VAC and converts it by switching its bridge at 1 kHz, which sets the granularity of the medium-frequency waveform. At the output terminals, the drive can deliver a continuous 2400 A, while the system’s rated operating point is 660 A, allowing the connected load to run efficiently under steady conditions. For short transients, the secondary circuit can withstand 120 kA without loss of waveform control. All logic and auxiliary functions are powered from a segregated 24 V DC supply, and a timer channel is provided for sequence coordination. Internal standby dissipation is limited to 100 W of cabinet loss, which helps moderate heat buildup in the enclosure.
Thermal management is handled by a water-cooled heat exchanger that can reject up to 4400 W of switching and conduction loss. A coolant flow of 10 l/min through the M16 × 1.5 threaded connectors maintains semiconductor junction temperatures as long as inlet water remains below 30 °C. The housing carries a protection level of IP20, so it is intended for cabinet installation and can operate in ambient temperatures up to 45 °C; maximum installation altitude is 2000 m before derating applies. Physical dimensions measure 860 mm in height, 396 mm in width, and 411 mm in depth, allowing straightforward rack mounting alongside other PSI components.
