The blown fuse indicator circuit is shown as the figure. The LED -R is used to the AC power indicator, andLED -G is used the fuse FU status indicator. When FU is normal, two LEDs arelit,and the light isorange; after FU fuses, LED -G turns off, and only LED -R emits red light. The current limiting resistors R10, R2 can be replaced by the 220nF/450V capacitor,then the VD1, VD2 can be eliminating.
