AC/DC DIN-Rail DC/DC Din-Rail
Available from stockArticle no.:A101.362
The PULS DIMENSION QS20.481 is a compact and efficient 480 W DIN rail power supply with a wide input range of 85 to 276 V AC. Its adjustable output voltage of 48 to 56 V DC and nominal output current of 10 A make it suitable for demanding industrial applications. BonusPower temporarily provides up to 150% of the rated power, or 720 W, while the integrated output capacitors support motor starting, high inrush currents and the absorption of regenerative energy. Efficiency of up to 94.3%, a potential-free DC-OK relay contact and spring-clamp terminals support reliable operation, straightforward diagnostics and fast installation.

Description
The most outstanding features of this Dimension QSeries DIN-rail power supply are the high efficiency and the small size, which are achieved by a synchronous rectification and further novel design details. With short-term peak power capability of 150% and built-in large sized output capacitors, these features help start motors, charge capacitors and absorb reverse energy and often allow a unit of a lower wattage class to be used. High immunity to transients and power surges as well as low electromagnetic emission makes usage in nearly every environment possible. The integrated output power manager, a wide range input voltage design and virtually no input inrush current make installation and usage simple. Diagnostics are easy due to the dry DC-ok contact, a green DC-ok LED and red overload LED. Unique quick-connect spring-clamp terminals allow a safe and fast installation and a large international approval package for a variety of applications makes this unit suitable for nearly every situation.
