Detailed description of the invention
Below in conjunction with drawings and Examples, this utility model is further illustrated.
As shown in Figure 2, in remote control feedback circuit, the second optocoupler N2 in Fig. 1 is cancelled by embodiment, and signal receiving end PC+ is connected to the input of the luminous organ N1A of the first optocoupler and the outfan of level output element U1, connecting an amplifying circuit controlled by remote signal at the outfan of the first optocoupler luminous organ N1A again, feedback signal can be amplified by amplifying circuit；As it is shown on figure 3, in main IC circuit, the signal receiving end PC+ of remote signal is joined in the feedback loop of FB foot of the light-receiving device N1B and main IC of the first optocoupler.By strengthen negative-feedback signal, thus reach by FB foot voltage pull-down to (FB foot voltage is 0V), after removing remote signal, power up normal operation.
