Circuit's load is relay or electromagnet coils of wire,and it alsocan be usedas the signal lightdisplay and alarm device etc. When it turns on the power switch, the input bonus of inverse's operational amplifieris added toUT, while in-phase input capacitor C has not been charged, so voltage is negative. Technical parameters: Working voltage: UB = 12V ± 12% delay time: tV is about 260S Repeat Time: tw is about 12s switch power: 120w ~ 3.5kW.
