DC Input Current Mode PWM Servo Amplifiers for Brush-Brushless Servo Motors

Elmo's analog servo amplifier family is a set of powerful servo amplifiers receiving analog commands and operating in current mode only. The amplifiers are designed to address the needs of brush and brushless DC motors. Each exhibits excellent servo performance, top efficiency, high quality and reliability - all in sleek and compact, high-density power packages. Outstanding motion control is achieved through the implementation of Elmo's proprietary switching and control methods enabled by fully customized, dedicated ICs and advanced heat transfer and dissipation methods.
