Optional integrated C1 EMC filters will allow the converters to be used in residential and commercial environments in compliance with DIN EN 61800-3. They are suitable for industrial applications, such as pumps, fans, compressors and conveyor systems, as well as for residential and business applications – such as refrigerated counters, fitness equipment, ventilation systems and commercial washing machines.

Commissioning and operation are said to be simple. A “keep running” mode allows continuous operation, even with fluctuating supply voltages. An improved cooling concept and coated printed-circuit boards provide electrical and mechanical ruggedness, allowing use in harsh conditions. The frequency converters can be connected to higher-level controllers via a built-in Modbus RTU/USS interface.

The Sinamics V20 range now covers seven frame sizes, spanning ratings from 0.12–30kW, for operation on 230V single-phase and 400V three-phase supplies.
