Product Description:
The PSI62C0.232-W1 medium-frequency inverter is produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It serves as a power conversion stage inside automated cells, taking factory mains power and delivering controlled medium-frequency output to connected equipment. This regulated output supports processes that require stable electrical energy and precise timing, including automated resistance welding applications.
The inverter connects to three-phase utility lines rated at 400 – 480 VAC and synchronizes with grids operating at 50 or 60 Hz. Its dual-frequency capability allows the same inverter configuration to operate with either supported grid frequency. A sealed coolant plate supports the water-cooled design, transferring heat directly to an external chiller loop and limiting temperature increases inside the enclosure. Under maximum load, the power stage releases up to 420 W of thermal losses, which the external cooling circuit must be able to remove. All live parts are contained within an IP 20 housing, so the inverter must be installed in a suitable electrical cabinet. The cabinet should protect the unit from dust, contact, and contaminants while providing adequate clearance around the coolant connections.
An integrated auxiliary supply delivers 24 VDC at up to 2 A. This supply can power sensors, relays, or a PROFIBUS timing module without requiring a separate low-voltage source. Reliable operation is supported at ambient temperatures from +10 to +55 °C, while the permitted storage temperature range is -25 to +70 °C. The 25 kg chassis requires a mounting structure capable of supporting its weight securely within the cabinet. The PROFIBUS timer interface coordinates the inverter’s firing pulses with a higher-level controller, enabling deterministic timing across multiple controlled devices or process zones. This communication path allows the automation controller to exchange timing and operating data with the inverter during synchronized production cycles.
