Product Description:
The PSI6200.322-W1 is a medium-frequency inverter produced by Bosch Rexroth Indramat for the PSI Frequency Inverters series. It serves as a power conversion block that delivers controllable medium-frequency energy to automation systems requiring stable, adjustable supply rails. The unit integrates its own 24 V logic supply and uses liquid cooling for operation in production-cell control panels where precise electrical power regulation is necessary. It is compatible with standard three-phase factory power, simplifying its connection to industrial electrical systems.
The inverter employs a water-cooled heat exchanger, so a closed fluid circuit removes most of its thermal energy instead of releasing it into the surrounding air. This cooling method allows the control cabinet to remain sealed and compact. The thermal load transferred to the coolant is 420 W, which establishes the required cooling capacity of the plant chiller. Electrical input is accepted from 400–480 VAC utility networks operating at either 50 or 60 Hz, allowing use in facilities with either supported line frequency. The housing has an IP20 protection rating, which shields live parts against finger contact but requires installation in a clean, dry enclosure. Suitable installation conditions fall under climatic category 3K3, covering typical industrial humidity and vibration levels.
The inverter’s integrated supply provides 24 VDC to its control electronics at up to 2 A. This supply can power compatible contactors, sensors, or the INTERBUS timer interface without a separate logic source. The unit remains fully functional at ambient temperatures from +10 to +55 °C. Storage and transportation are permitted from −25 to +70 °C when the coolant circuit is drained, preventing retained fluid from affecting the unit outside its operating range. The inverter has a mass of 25 kg, which must be considered when selecting cabinet supports and mounting hardware. Adequate clearance should also be maintained for the coolant connections, electrical conductors, and enclosure ventilation requirements.
