7. Principle of operation and product design.

Stabilizers RUCELF are the electromechanical type of the stabilizers,

which provide stepless control of the output voltage, with high precision of it.

Regulation is running with servo drive, which automatically traces changings of

input voltage. Output voltage is measuring and comparing with standard voltage

of control unit.

In case of deviation, servo drive starts to work, adjusting the boosting

voltage to the reference value of output voltage.

The value of boosting voltage either increases, or is subtracted from the

corrupted line voltage. Digital board with microprocessor management is set on

the stabilizers RUCELF. The digital board makes the logical control of protection

on the down and up limit. The temperature sensor protects the stabilizer from

the overheating and disconnects the output load during abnormal operation

temperature.
