How to wire the voltage regulator/voltage regulation module?

INTRODUCTION:

The function of the voltage regulator/voltage regulation module is to adjust the supply voltage to a voltage value suitable for load operation through internal voltage regulation circuit.
According to the voltage regulation mode, the voltage regulator/voltage regulation module can be divided into potentiometer type, analog signal type, digital signal type and external transformer type. The potentiometer type regulates the voltage by means of an external potentiometer. The analog signal type regulates the voltage by means of a control signal with a continuously variable voltage. The digital signal type regulates the voltage by means of pulse signal. The external transformer type regulates the voltage through a potentiometer based on the reference voltage provided by the external transformer. According to the control mode, the voltage regulator/voltage regulation module can be divided into automatic control signal type and manual control signal type. The automatic control type automatically regulates the voltage by the control signal from the control device. The manual control type regulates the voltage by manually adjusting the potentiometer.
