Product Description:
The PSI6100.202-L1 is a medium-frequency inverter produced by Bosch Rexroth Indramat within the PSI Frequency Inverters series. It is intended for industrial automation tasks that require a dedicated electronic source capable of converting standard mains power into regulated medium-frequency power. This conversion allows accurate energy control for connected electrical loads. Forced-air cooling keeps the power stage compact without requiring an external liquid-cooling circuit. The unit is suitable for installation areas that meet the EN 60721-3-3 climatic class 3K3 requirements.
The inverter accepts a three-phase supply ranging from 400 to 480 VAC, allowing direct connection to common factory distribution systems. It supports a line frequency of 50 or 60 Hz, making it suitable for electrical systems used in Europe and North America. A built-in auxiliary supply delivers 24 VDC at up to 2 A. This auxiliary channel can power compatible relays, sensors, or fieldbus nodes without a separate control transformer. The enclosure provides IP20 protection, which guards against accidental contact with hazardous internal parts but requires cabinet installation where dust or moisture may be present. PROFIBUS connectivity supports parameter exchange and coordinated communication with higher-level control systems.
During full operation, the unit releases 360 W of heat, so cabinet airflow must remove this thermal load without directing heated air toward adjacent electronics. Continuous operation is permitted at ambient temperatures from +10 to +55 °C, covering the conditions found in many controlled industrial locations. The permitted storage and transportation temperature range is -25 to +70 °C, allowing the unpowered inverter to withstand broader temperature changes. The difference between the operating and storage ranges should be considered when equipment is moved from an unconditioned area into an active control cabinet. The inverter weighs approximately 20 kg, so its mass must be considered when selecting mounting supports and handling equipment. Adequate clearance around ventilation paths helps prevent heat from accumulating near the power stage and nearby control components.
