Civil power is from the 1 of transformator, 2 inputs, and 3,4 is self-coupling tap, and 5,6 are the power supply of control circuit and sampling is taken out
Head, when line voltage is normal, because C point voltage is always 3V(i.e. R1 blood pressure lowering DW voltage stabilizing gained), A, B point is all higher than
3V, therefore A1, A2 output low level, when line voltage declines, the voltage of 5,6 declines the most therewith, A point voltage also with
Decline, when A point voltage drops below 3V, A1 exports high level, makes audion V1 saturation conduction, relay
K1 adhesive, adjusts in 1,3 by pressure regulator output, when line voltage continues to decline, when in like manner B point voltage is less than 3V,
(VA < VB), A2 exports high level, makes V2 saturation conduction, K2 adhesive, adjusts in 1,4, to reach by pressure regulator output
The purpose of self coupling boosting, during whereas if voltage raises, B point voltage also increases, when B point voltage is higher than 3V,
A2 output low level, V2 ends, and H2 discharges, and outfan is adjusted to 1,3, when line voltage continues to raise, A point voltage
Higher than 3V, A1 output low level, V1 ends, and K1 discharges, and outfan is adjusted to 1,2, and A1, A2 are operational amplifier,
Here being used as voltage comparator, IC1 is three-terminal regulator block, and it is operational amplifier and relay offer power supply, VD5,
