SCA601 Linear Servo Controller


The SCA601 Linear Servo Controller was specifically designed to control single phase, non-comutated devices like voice coil motors. It is a high performance single axis DC motor controller and amplifier system. It is comprised of a highly integrated single PC board level product with a cohesive interface and a compact heat sink. This card provides current amplification and analog servo control interfaces. The single-phase characteristic of the very low noise current amplifier makes it particularly well suited for DC motors such as galvanometers and voice coils. It was specifically developed for control of motor applications requiring both high temporal and spatial servo precision, such as machine vision, inspection, scientific imaging, medical imaging and other business applications. This amplifier interfaces directly to most of the Equipment Solutions motor/stage solutions.


A bipolar linear or switching regulated power supply is required to operate the SCA601 amplifier. Typically better performance can be achieved when using a linear power supply. Equipment Solutions has several high-current supplies for this purpose including the SPS15 ±15V DC Switching Power Supply.
