Features and benefits:

• Integrated braking chopper eliminates the need for an external unit in deceleration-heavy applications
• Wide input voltage range (380-480 V) supports use across IEC and NEC installations
• USS and Modbus RTU communication allow direct integration with PLCs and automation systems
• Analog inputs can be reconfigured as digital inputs, increasing I/O flexibility
• Side-by-side mounting capability reduces panel space requirements
• IE2 efficiency class with measured losses per IEC 61800-9-2

Applications:

• Variable speed control of 3-phase AC motors in pump and fan systems
• Conveyor and material handling drives requiring controlled acceleration and deceleration
• Industrial machinery where Modbus RTU or USS communication to a PLC is required
• Installations where an external EMC filter is fitted at system level (unfiltered variant)
• Panel-mounted drive systems with space constraints benefiting from side-by-side mounting

Compliant with EN 61800-5-1, EN 60204-1, and EN 61800-3. Part of the Siemens SINAMICS V20 range.
