Servo Amplifier (Sva-ii)

Our range of Servo Amplifier (SVA-II) is a box type amplifier with self-contained DC stabilized power supply, mainly for driving and one-stage closed-loop controlling of nozzle flapper servo valve and jet pipe servo valve, etc. It uses a portable standalone box, and is easy to use. The front board is provided with a potentiometer with a scale locking mechanism for easy parameter adjustment. An ammeter is used for displaying the valvea s coil current for easy observation in commissioning. You can select LVDT demodulation board as necessary for controlling a closed loop having LVDT detection sensor.
