Frequency Converter SD2M DC
The frequency converters of series SD2M DC convince by their maximum output, little need for space, reduced system costs and high efficiency. The devices are designed for complex automation tasks in high-speed applications and allow use of synchronous and asynchronous motors.
Sensorless applications as well as applications with speed sensor can be realized easily. The high-dynamic vector control combined with highest speeds offers a whole new range of applications.
Highlights
The Powerful One
SIEB & MEYER has developed the frequency converter SD2M DC using the three-level tehnology to significantly reduce PWM-related rotor losses.
In addition to the SD2M Turbo devices for 3-phase mains supply, devices with DC supply are also available. These devices allowe to optionally operate SD2M DC with a power supply unit capable of recovering energy. This way applications with a process-related repeated braking operation can take advantage of the benefits of the three-level technology.
