1) BOX Type Control amplifier ,

2) the AC 220 V Power ,

3) Provides DC±15V and DC﹢5V , the DC﹢5V is for power of Digital ammeter.

4) with a choseable current,  

5) It can show servo valves' current value without vibration signal by Digital display. 

6) Convenient operate on panel .

7) Be used for closed loop controlling,also for open-loop controlling.  

8) Input signal and feedback signal will be amplified and then be to the Adder, and then after the

driven stage amplified, then driving the Servo valve.  

9)  It can add the appropriate flutter signal.

10) More other technology requests optional. 

Stable

It has a low drift and a high stability, which makes the system with a long stable working status .

Flexible

It is very flexible because of switches on the board for setting zero, adjusting input gain, feedback gain,gain amplification .

Unique circuity

It has an unique design of power amplify circuity . Which can be fit for different kinds of servo system, and also Built-in protecting circuit and against over-current to ensure security.

Visualized output current

It adopts digital display ammeter, The current running coils is very clear with ±0.1mA precision.

Convenient for maintenance

We can check and repair it according to its simple structure and complete Schematic diagram.
