PULS QS3.241 INTRODUCTION
The most outstanding features of this Dimension QSeries DIN-rail power supply are the high efficiency and the small size, which are achieved by 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 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 a 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.
