How to wire the Solid State Voltage Regulator?

The solid state voltage regulator can adjust the power supply voltage to a voltage value suitable for load operation through its internal voltage regulation circuit. According to the voltage regulation mode, the solid state voltage regulator can be divided into the potentiometer type solid state voltage regulator, the analog signal type solid state voltage regulator, the digital signal type solid state voltage regulator and the external transformer type solid state voltage regulator. The potentiometer type solid state voltage regulator adjusts the voltage by means of an external potentiometer. The analog signal type solid state voltage regulator adjusts the voltage by means of a control signal with a continuously variable voltage. The digital signal type solid state voltage regulator adjusts the voltage by means of pulse digital signal. The external transformer type solid state voltage regulator adjusts the voltage through the potentiometer based on the reference voltage provided by the external transformer. According to the control mode, the solid state voltage regulator can be divided into automatic control signal type solid state voltage regulator and manual control signal type solid state voltage regulator. The automatic control type solid state voltage regulator automatically adjusts the voltage by the control signal from the control device. The manual control type solid state voltage regulator adjusts the voltage by manually adjusting the potentiometer. Sometimes, we integrate the solid state voltage regulator and its peripheral circuitry into the solid state voltage regulator module to reduce the size and increase the convenience and stability.
