PULS XT40.481 INTRODUCTION
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 lightweight
design, along with compact dimensions, facilitates
straightforward mounting on a DIN rail.
Primary use is 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 main transformers with rectifiers.
