Working Principle

The L6R09H-070 AC/DC power supply is divided into two parts. The AC/DC power conversion section and the voltage/current control section. The AC/DC power conversion section consists of a rectifier bridge, step up transformer, voltage regulator, filter circuit and other components. AC power is converted to DC power through the rectifier bridge, step up transformer and voltage regulator. The voltage and current control section consists of an active regulation circuit and a voltage and current control circuit. The active regulation circuit actively modulates the midpoint of the output voltage to ensure the stability of the output voltage within the specified working range and simultaneously completes the over current protection, over voltage protection and short circuit protection functions. The voltage and current control circuit adjusts the output voltage and current to ensure the accuracy of the output voltage and current. Finally, the output is filtered and stabilized to output stable and accurate voltage and current, and all the operation is completed automatically.
