Product Description:
The PSI65C0.232-W1 is a medium-frequency inverter manufactured by Bosch Rexroth Indramat for the PSI Frequency Inverters series. As a drive component, it converts fixed three-phase mains power into adjustable medium-frequency power that machine controllers use for accurate motor speed or process energy regulation in industrial automation cells. This inverter type supports applications such as induction heating and high-speed spindles where consistent output quality is required.
The inverter uses a water-cooled circuit that draws heat away from the power stage, allowing full output in tight enclosures. Its housing carries an IP20 degree of protection, so it must be mounted inside a cabinet but remains protected against accidental finger contact. The unit accepts a three-phase supply of 400–480 VAC at a mains frequency of 50 or 60 Hz, matching common plant power systems without a transformer. An integrated supply delivers 24 VDC control voltage for sensors, relays, or the PROFIBUS timer interface, eliminating the need for a separate auxiliary supply. The unit is suitable for sites classified as climatic category 3K3 under EN 60721-3-3, including production areas with moderate temperature, humidity, and dust. The PROFIBUS timer function synchronizes inverter cycles with commands from a higher-level PLC.
The internal power supply can deliver up to 2 A, allowing low-current field devices to be wired directly to the inverter. During full-load operation, the cooling circuit must remove up to 420 W of thermal loss, which is relevant when selecting heat exchangers and setting coolant flow rates. Continuous operation is permitted from 10 to 55 °C, while the electronics can withstand storage or transport temperatures from -25 to +70 °C without performance degradation. The inverter has a transport weight of 25 kg, which should be considered when selecting cabinet supports, mounting hardware, and handling equipment.
