Principle of operation Block diagram of the voltage stabilizer Fig The structure of the device includes control system CS switching transformer ST and indication system IS When mains voltage is available Uin the CS while analysing its value operates the ST which appropriately switches taps of primary winding of the ST and output circuits of the device thus providing the required value of output voltage Uout and displays the operating mode on the front panel with the help of IS Output voltage control is performed based on the following algorithm If the mains voltage Uin stays within the range of 1 10 5V to 260 5V then the output voltage Uout 220V 8 not less than 202 4V and not exceeding 237 6V If the mains voltage Uin Is lower than 110V then Uout equals to the mains voltage increased by 100 Uout 2 0 x Uin until it reaches the value of Uout 180 5V which is shutdown threshold of the AVS If Uout becomes less than 180 5V then output voltage would be disconnected Uout 0 If the mains voltage Uin is higher than 260V then Uout equals to the mains voltage decreased by 10 Uout 0 9 x Uin until its value reaches 260 5V which is upper threshold if Uout Exceeds the value of 260 5V the output voltage would be disconnected Uout 0 After mains voltage is resumed after its falling beyond the limits of the working range or full disconnect the voltage stabilizer would automatically supply output voltage to the load Connection is made with a time delay in order to avoid transfer to the load of surges and distortions of sine wave voltage occurring during connections to electric mains In case where a refrigerator or conditioner is connected to the voltage stabilizer we recommend to use the function of increase of the time delay WWW POWERMAN RU
