Dedrive Compact STO
Outstanding drive performance combined with maximum functionality
Our Dedrive Compact STO frequency inverters offer outstanding performance and satisfy even the most demanding drive requirements with ease. They feature not only tried-and-tested reliability and functionality, but also:
- high overload capability
- simple operation
- control characteristics for travel and lifting applications independent of the load
- can already be used for 0.75 kW recommended motor shaft output
- highly cost-effective thanks to low wear on the drive system
- application modules are also available with Dedrive Compact STO
