Medium voltage converter
Innomotics SL150
The Innomotics SL150 cycloconverter with thyristor stacks is an optimal solution for controlling the low-speed and high-torque induction and synchronous motors. Designed as three-phase thyristor bridges in 6 or 12-pulse connections, they are robust and ideal for rolling mills, powering mine winders, conveyors, grinding mills and excavators.
Benefits at a glance
- Fewest drive components for any given power rating
Low component variety to reduce capital investment and associated costs for storage and logistics. - Compact and rugged design for extreme environments
High altitudes, temperatures and air quality, plus service friendliness for remote areas.
- Optimal configuration and operation
Integrated test routines, feedback and self-diagnostics, including thyristors, improved commissioning and tuning.
Use of standard HV cable due to the typical low switching speed of thyristors (no screened or armored cables required).
