It is taken within the scope of electric output power standby, when output voltage variation, output voltage gets higher or is lower, and can pass through resistance
The COMP foot of R8, voltage-stabiliser tube Z1, optocoupler U1, the COMP of feedback to control chip IC 1, the control chip IC 1 are to sample light
The curent change of the receiving end coupling U1 collection emitter-base bandgap grading, the control meeting adjust automatically OUT foot PWM duty cycle of chip IC 1, the transformer BYQ1
Primary energy will increase or decrease, to maintain the output of constant voltage；
The intelligent control panel is equipped with the terminal device and the common I/O port of MCU of 2.4G WIFI, MCU common I/O port and light
The emitting diode anode of coupling U2 connects, so that it may control the Push And Release of load.
