Desktop power supplies are practical and popular 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. The new POS desktop power supplies of the POSC series are such a solution.
The POSC series consists of 22 products. Depending on the model their output voltage ranges from 12 V to 48 V DC and the nominal power is 24 W to 120 W. This meets the needs of most electronic devices powered by this type of power supplies. Their great advantage is a wide input voltage range from 90 V to 264 V AC (at a frequency of 47 … 63 Hz) and the use of C8 and C14 input connectors – they can be used all over the world. The following table shows a cross-section of other parameters of the POSC series.

One of the main advantages of the presented products is MTBF (mean time between failures) of 100 000 h. Moreover, these devices can work in the ambient temperature from -5 ° C 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).
