SVA-III-M servo amplifier is a box type amplifier, which is a SVA-III board type amplifier integrated with standard 19-inch power chassis. Its controlling functions are same with that of SVA-III board type amplifier. It is mainly for controlling 3-stage valve with LVDT position sensor, has a LVDT demodulator circuit, and realizes closed-loop controlling with the inner loop of the servo valve's coil, and is also of PID controlling of outer loop. By different settings of the jumping switch, it can also be used for controlling closed loop of position formed by a 2-stage servo valve and LVDT sensor. It is furnished with an integrated linear power supply. You can supply AC220V directly. It uses a standard casing. The front board ammeter indicates the valve's coil current for easy observation in commissioning.
