PWM with L/C filtered DC-output

SERVOWATT PWM power amplifiers can be used for servo, current or voltage control. These high-quality PWM DC power amplifiers permit cost-effective and technically optimum solutions in many areas of drive, measurement and control technology due to their proven and universal design. Applications as servo drives with high-power DC motors in different kinds of high-quality machines, as bipolar voltage and current regulators in plant and measuring and test equipment. The L/C low pass filter at the output prevents spurious EMC emissions on the load.
