Assignment:
The control device of AVR-01-K is intended for creation of schemes AVR with two inputs of a power supply, one loading.
Principle of work:
The control device of AVR-01-K controls tension on two inputs of the three-phase alternating current main. If tension within norm, loading is connected to the main input by means of the external switch (the contactor, the time cut-out with the motor drive, etc.) which is managed by the AVR-01-K final-control relay. At accident loading is connected to reserve input of a power supply. At recovery of a power supply on the main input loading switches to it. A power supply of AVR-01-K is carried out from controlled inputs.
