Product Description
The DIMENSION X-series power supplies include a new and innovative concept for generating an isolated DC voltage from a three-phase mains system. A semi-regulated resonant converter enables a very compact design, maximum efficiency and extremely competitive pricing with only a small compromise in the output voltage regulation, output ripple and hold-up time. Weighing just 1.4 kg, the device provides 960 watts of continuous output power and an additional 25 % power reserve for dynamic loads. The light-weight design along with compact dimensions facilitates straightforward mounting on DIN-rails. Primary use are applications involving supplies to motors, valves and other load circuits with a high power consumption and where an accurate output voltage regulation (which is standard on traditional switched-mode power supplies) is not required. Furthermore, these switched-mode power supplies can often replace mains transformers with rectifiers.
