Technovision TVS-S1 User Manual page 13

Any three phase servomotor stabilizer has only one electronic control card for all the phases and one
Display card for its monitoring and complete control, less those ones that consist of three independent
single phase equipment's duly connected to make a three phase equipment. In these ones, each cabinet
will have its own electronic control card and its display card.
Depending on the total power of the three phase equipment's, no matter if they include some options or
not, they are supplied assembled in one metallic cabinet, and divided in two cabinets joined together
mechanically at factory or by three separate cabinets, which will be joined after their final location. The
input and output are marked in the terminal strips of the equipment. When installing the device, use the
suitable cross cable section in order to guarantee its correct operating.

The LCD display of the control panel of the stabilizer allows checking the input/output voltages and
frequency, whenever you need. Also, the LCD has measurements of Load current per phase. There are LED
indicators to indicate Phase indication. Block diagram of a Servo Voltage Stabilizer is shown in Fig. 4 (the
three phase structure is similar to it but repeating the same block per each phase).
Figure 4 Block Diagram of Servo Voltage Stabilizer
The LCD Display shows the values of the input/output voltages (Phase to Phase & Phase to Neutral) and
frequency. And also measure output current with the output current transformers. Also, the LED indicators
inform about Phase indication. To know in detail the LCD panel information and the meaning of the LEDs go
to the corresponding section of this manual. The input circuit breaker protections, provides protection
against long over currents to both the loads and the stabilizer. Depending on the model and the protection
degree IP, the cooling is natural or forced, in order to keep the internal temperature stable.
