Voltage range: 3AC 380-480 V (+ 10%/-10%) Frequency range: 47-63Hz Overload capacity: High Overload protection level: IP20 Built-in brake chopper: Yes No Built-in filter: Yes Input voltage fluctuation range: + 10%/-20% The SIEMENS 6SL3210-1PE22-7UL0 power module is a high-performance power module designed for industrial automation systems. Its built-in A-class filter can effectively reduce the current fluctuation and improve the stability and reliability of the system.At the same time, the built-in brake chopper can respond quickly when the load changes to ensure the normal operation of the equipment. The module is suitable for the AC voltage range of 380-480 V and can operate stably in the frequency range of 47-63 Hz. Its high overload capability enables the module to maintain efficient operation in the face of sudden large loads. In addition, the module has IP20 protection and can operate reliably in a variety of industrial environments.
