SEMI-REGULATED POWER SUPPLY • • • • • • • • • • • • • Alternative or Replacement for AC Transformer Three Phase Input – DC Output DIN-Rail Mountable Width only 96mm 95.5% Efficiency 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 3 Year Warranty 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.

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. Power Supply Output voltage Adjustment range Output current Jan. 2007 / Rev. 1.0 DS-XT40.72x-EN All parameters are specified at 72V 13.3A, 3x400Vac (XT40.721) or 3x480Vac (XT40.722), 25°C ambient and after a 5 minutes run-in time unless otherwise noted. www.pulspower.com Phone +49 89 9278 0
Open the catalog to page 1INTENDED USE The power supply shall only be installed and put into operation by qualified personnel. This power supply is designed for installation in an enclosure and is intended for the general use, such as in industrial control, office, communication, and instrumentation equipment. Do not use this device in aircraft, trains and nuclear equipment, where malfunctioning of the power supply may cause severe personal injury or threaten human life. PE is the abbreviation for Protective Earth and has the same meaning as the symbol Earth, Ground This document uses the term “earth” which is the...

Open the catalog to page 58. HOLD-UP TIME Hold-up Time Hold-up Time The energy is stored in the output capacitor. As soon as the input is turned off, the output capacitor will be discharged and the voltage will dissipate according to the curves in Fig. 8-2. The lighter the load, the longer the hold-up time. Half the load means twice the hold-up time. The hold-up time depends on the load characteristic. The curves below show the hold-up time for a load with a resistive and a constant power characteristic. The hold-up time is defined as the period of time when the input is turned off and until the output voltage falls...
