Being able to accommodate an input voltage swing in excess of 40%, whilst still delivering

accuracy on the output of 1% or better, the Servo Electronic design principle comprises a

transformer having its secondary winding connected between the mains supply and the load.

The primary voltage is automatically controlled through a servo motor driven variable

transformer, thereby ensuring a continuous, smooth and very stable output voltage.

A solid state Servo-Amplifier continuously monitors the output voltage of the stabiliser.

Should, due to an incoming voltage or load current change, the output voltage deviate from

the required value, the Amplifier sensor instructs the servo motor to rotate the brush-gear on

the variable transformer to correct the output for the deviation. The speed of detection and

actions of the servo system are exceptionally fast, with controlled motor deceleration to

minimise any possibility of overshoot.

Over the years with advances in semi-conductor, motor and digital technologies, our

development engineers have considerably enhanced the performance of the basic design

principle. Our latest Servo Electronic generation of solutions deliver the most reliable, fastest

acting, highly stable and most energy efficient operation seen in the market today.
