The module is designed for rectifying, filtering, and stabilizing AC or DC voltage. It is based on the linear voltage regulator 7809 and provides a stable 9 V DC output.
The module is suitable for powering electronic devices with current consumption up to 1 A. The PCB includes input and output terminals, allowing connection of either AC or DC input voltage.
An LED indicator shows the presence of stabilized output voltage. When higher power dissipation occurs, a suitable heatsink must be mounted on the voltage regulator.

Technical Specifications:
Integrated circuit: 7809.
Input voltage: 12 - 20 V AC or up to 26 V DC.
