NSP-SERVO-AC-30 Series High-Precision High-Voltage AC Servo Drives for Industrial Automation

Independently developed by ZGC, the NSP-SERVO-AC-30 series is a high-performance AC input servo drive compatible with 1000W-3000W high-voltage DC servo motors, encoder-equipped BLDC motors, and coreless motors. With a wide input voltage range of 90V-260V AC, it boasts industry-leading precision (1 pulse repeat tracking error, 1 RPM speed control accuracy) and supports three control modes: position, speed, and torque, enabling flexible control via external pulses, analog input, RS485, or CAN bus. Integrated with comprehensive protection functions such as undervoltage, overvoltage, and overload protection, and supporting RS232 PC debugging, it is ideal for precision motion control, industrial automation, and robotics applications.
