The powerful drivetrain inverter DTI844 can be used to control different motor types. The power output stage is based on the highly efficient, resonant SoftSwing® topology, which was developed and patented by BRUSA. The SoftSwing® topology achieves minimal switching losses. This allows applications with motor frequencies of up to 3 kHz. Due to its compact and lightweight design, the DTI8 is suitable for almost all applications and predestined for use in high performance drives.

Designed, end assembled and tested in Switzerland

Features

  • Resonant SoftSwing® topology for minimal switching losses and superior EMC properties
