POS POSC series switch mode desktop power supplies

Desktop power supplies are practical solutions for both industrial and consumer equipment. Current conversion circuits are among the most important electronic circuits — and at the same time they are prone to failures caused by external factors (power surges, short circuits, etc). The use of high-quality power supplies extends the life of equipment and improves user safety. POS’s POSC series desktop power supplies are an example of such a solution.

The series consists of 22 products. Depending on the model, the output voltage ranges from 12 V to 48 VDC and the nominal power is 24 to 120 W. This meets the needs of most electronic devices powered by this type of power supply. The devices have a wide input voltage range from 90 V to 264 VAC (at a frequency of 47–63 Hz) and use C8 and C14 input connectors, so they can be used all over the world.

The products have a MTBF of 100,000 h and can work in ambient temperatures from -5 to +40°C (and humidity up to 95%). Protection functions include overcurrent protection, short circuit protection and overvoltage protection. In all cases, the power supplies automatically return to normal operation when the fault is removed.

POS devices comply with a number of international standards, such as EN 62368 (power supply standards for audio/video, IT and communication products) and EN 55032 and EN 61000 (electromagnetic compatibility of multimedia equipment – emission requirements).
