Semi-Regulated Power Supply • Alternative or Replacement for AC Transformer • Three Phase Input - DC Output • DIN-Rail Mountable • 125% Peak Power Capability • No Input Inrush Current • Active Input Transient Blocker • Full Power Between -25°C and +60°C • Easy Failure Diagnostics • No Electrolytic Capacitors on Input Side • Cost Effective and Robust 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.
