Atlas® Amplifiers are compact single-axis amplifiers that provide high-performance torque control for Brushless DC, DC Brush, and Step motors. They are packaged in a compact, solderable module and are ideal for use in positioning motion control, velocity control, and precision force control applications. Atlas amplifiers come in both a vertical and horizontal mounting configuration and are available in three power ranges: 75W, 250W, and 500W. They are ideally suited for applications such as medical equipment, laboratory automation, scientific instruments, general-purpose motion control, force feedback, and actuator control.

  • Ultra-efficient all digital solderable power amplifier
  • Controls Brushless DC, step, and DC Brush motors
  • Available in 75W, 250W, and 500W power levels
  • Operating supply voltage range of 12V to 56V
  • FOC (Field Oriented Control)
  • Overcurrent, overvoltage, undervoltage, and overtemperature protection
  • SPI (Serial Peripheral Interface) torque command input
  • Two different package sizes available
  • Works with Magellan® ICs, FPGAs or microprocessor-based controllers
  • Comes in horizontal and vertical mount configurations
