Embodiment Construction
[0046] Below in conjunction with example the present invention is described in more detail:
[0047] Such as figure 1 As shown, the output terminals of the AC / DC module are connected to the input terminals of the voltage regulators U1 and U2, and the AC / DC module provides DC power to the voltage regulators.
[0048] The adjusting terminal of the voltage regulator is connected with the middle taps of the digital potentiometers U3 and U4, and adjusting the position of the middle taps of the digital potentiometers can change the output voltage of the voltage regulator.
[0049] The serial communication port of the digital potentiometer is connected to the general SPI port of the single-chip MCU, and the data received by the serial communication port can change the middle tap position of the digital potentiometer.
[0050] The output terminal of the voltage regulator is connected to the contact of the relay, and the single-chip MCU controls the conduction and disconnection of the...
