303P by Copley Controls

The Copley Controls 303P is a robust DC servo amplifier from the DC Servo Amplifiers series, designed by Copley Controls for demanding industrial and automation applications. With a nominal voltage range of 20-80V DC and a power output of 600W, this unit delivers high efficiency and precision control for robotics, CNC machinery, and packaging systems. The amplifier’s primary function is to convert DC power into finely tuned motor drive signals, ensuring accurate motion regulation and reliable performance in critical environments.

Incorporating advanced control algorithms, the 303P offers continuous current handling of 7.5A and peak current capability up to 15A, accommodating sudden load changes and dynamic motion profiles. It supports multiple control modes—Current, Velocity, and Position—and provides versatile feedback interface options including encoders, resolvers, and Hall sensors. The amplifier’s communication interfaces—Analog ±10V, PWM, and Step/Direction—ensure seamless integration with a wide range of motion controllers and PLCs. These technical features allow engineers to optimize system response, reduce tuning complexity, and achieve high-speed, precision-driven applications.

Built to withstand harsh operating conditions, the 303P operates reliably from 0°C to 70°C and can be stored between –40°C and 85°C. Its compact, lightweight design (approximate 300g weight) and IP20 protection class make it suitable for space-constrained installations. Certified to CE and RoHS standards, this amplifier meets rigorous safety and environmental requirements. By offering rugged construction, versatile interfaces, and compliance with global certifications, the 303P enhances system uptime, simplifies integration, and delivers consistent, high-performance motion control for industrial automation and robotics.
