ETEL DSC2P131-111-000 Linear Servo Amplifier – 10Arms/30Arms
The ETEL DSC2P131-111-000 is a dedicated linear servo amplifier designed to drive three‑phase linear motors with exceptional precision. It delivers a continuous current of 10 Arms and a peak current of 30 Arms for up to 1 second, making it suitable for applications requiring high force and rapid accelerations. This amplifier is part of the DSC2 family, sharing the same advanced digital architecture and robust construction.
Linear motors place stringent demands on amplifiers due to their low inductance and high dynamic requirements. The DSC2P131-111-000 meets these challenges with a high‑frequency current loop, advanced PWM modulation, and sophisticated filtering to minimize cogging and force ripple. The result is ultra‑smooth motion even at low speeds, essential for scanning and positioning tasks.
