NCSA-110-300 Servo Amplifier

The NCSA-110-300 is designed as a general purpose amplifier compatible with all types of servo valves requiring closed loop current control. It works with servo valves from Moog, Parker, Bosch Rexroth, Vickers, and other manufacturers that require current output drive (up to 250ma). The adjustable gain settings and flexible input options enable compatibility with a wide range of feedback sensors and command sources.

Yes. As shipped, the NCSA-110-300 has adjustable output current from 0ma to 100ma. With a simple component change (documented in the manual), you can increase the maximum output to 250ma. This flexibility allows you to configure the amplifier for different servo valve current requirements without ordering multiple product variants.

The NCSA-110-300 accepts both voltage and current signals for command and feedback inputs. Specifically, it supports ±10V voltage signals or 4-20ma current signals for both the command reference input and feedback input. This versatility enables integration with PLCs, analog controllers, potentiometers, LVDTs, and various other sensor and command source types.

The built-in 500 Hz dither oscillator improves servo valve performance by reducing static friction and improving response to small command signals. Dither introduces a small amplitude, high-frequency signal that keeps the valve spool in constant motion, preventing stiction and enabling finer position control. This feature is standard on the NCSA-110-300 and can be enabled or disabled as needed.

Yes. The NCSA-110-300 includes a regulated ±15V power supply output at 200ma capacity, available directly at the terminal strip. This output is designed to power LVDTs, potentiometers, and other feedback sensors or auxiliary equipment. The regulated output ensures stable sensor excitation for accurate feedback signals.

The NCSA-110-300 features clearly labeled test points and components throughout the board design. Key signal points (command input, feedback input, error amp output, current command) are easily accessible for measurement with standard test equipment. This clear labeling reduces troubleshooting time and makes it easier for technicians to diagnose issues without extensive documentation.

The NCSA-110-300 offers three key adjustable parameters: feedback gain adjustable from 2:1, reference span adjustable from 200:1, and proportional error gain adjustable from 200:1. These wide adjustment ranges allow you to tune the amplifier response for different servo valve characteristics, feedback sensor types, and command signal levels without external signal conditioning.

Yes. Complete technical documentation including terminal connection diagrams, test point locations, adjustment procedures, and component change instructions is provided with each NCSA-110-300 unit. Additional support is available from NC Servo Technology at 734-326-6666 or through our website at ncservo.com.

Yes. The NCSA-110-300 is designed to replace many obsolete amplifier models across multiple manufacturers. Its flexible input options, adjustable output current, and wide gain adjustment ranges enable it to substitute for legacy amplifiers that are no longer available.
