Concept and function

The PNI ST105 switching voltage supply converts the power supply from the 230 V AC mains into a DC voltage (13.8 V nominal) and supports a direct current of up to 5 A, with a peak of up to ~7 A. With this function, the device is suitable for powering electronic equipment that requires a 12 V DC power supply.

Main technical specifications

The ST105 supports an input voltage of 230 V AC ±20% at 50 Hz, with an output of 13.8 V DC ±2%. The ripple (ripple voltage) is no more than 100 mVp-p, which indicates a low level of electrical noise.

Advantages in use and typical applications

Thanks to its switching technology, the ST105 offers high efficiency and low losses, facilitating long-term stable operation with protection against overload and unstable voltages. It is ideal for applications such as CCTV systems, access control and other installations that require stable power supply at 12 V DC.

Installation & safety

• Installation is intuitive: connect the load to the output terminals (+ and -), after checking the polarity, then the unit is powered by the 230 V AC mains and switches to the ON position for switching on (LED indicates the operating status). It is recommended that the load be limited to ~80% of the rated current to ensure durability. In addition, it is necessary to install in a space with adequate ventilation, without blocking the cooling holes, and avoid exposure to moisture or dust, to prevent overheating or malfunctions.
