The power supplies in the Dimension X-Series 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 facilitate

straightforward mounting on DIN-rail.

Primary use are applications involving supplies to

motors, valves and other load circuits with a high

power consumption, 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.
