The C-Series power supplies are affordable basic units comprising an alternative to the feature-rich Q-Series. Corners were cut when it comes to a few features, but not in terms of quality, reliability, ease of operation, small overall size and generous power reserves. In this sense, the same standards apply to the C-Series as to all other PULS products. In the 120W class, the C-Series units are even smaller than those of the Q Series and yet are every bit as durable, with a specified life expectancy of the electrolytic capacitor of 50,000 hours.
The guaranteed power boost of +20% of the rated power is intended to ensure optimal adaptation to fluctuating loads. If the ambient temperature remains below 45°C or with forced ventilation, this performance is even specified for continuous loads. Nor were any compromises made when it comes to limiting the inrush current. This unpleasant side effect of switching power supplies was completely eliminated by means of a new circuit.
The units are equipped with automatic 115/230V range switching for increased ease of operation and fault avoidance. For the first time, the units are now available in special regional versions that cover either only the 100-120V or 200-240V ranges. This made it possible to further reduce costs without other disadvantages in regional applications.
