High-frequency frequency converter SFU 400

synchronousasynchronousvector control

•Sensorless operation of asynchronous and synchronous motors •Speed frequencies up to 100.000 rpm (1666 Hz) •Continuous output power: 380 VA / S1 – 100% •Digital signal processor (DSP) •On board chopper brake resistor •High precision sinusoidal output signals with a low distortion factor and low deformation allow for optimal rotation qualities in AC motors of all operating conditions •All parameters like power, voltage and frequency are collected in real time and are regulated by the implemented vector control depending on the load. •High operating safety: All operating conditions like acceleration, operation with nominal rotation speed, braking are controlled and critical conditions are intercepted. •Short circuit protected •Protection against excess temperature
