POWER SUPPLY AC 100-240V Wide-range Input Width only 60mm Efficiency up to 92% 150% (360W) Peak Load Capability Easy Fuse Tripping due to High Overload Current Active Power Factor Correction (PFC) Negligible low Inrush Current Surge Short-term Operation down to 60Vac and up to 300Vac Full Power Between -25°C and +60°C DC-OK Relay Contact Quick-connect Spring-clamp Terminals 3 Year Warranty GENERAL DESCRIPTION SHORT-FORM DATA 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. The QSeries is part of the Dimension family, existing alongside the lower featured C-Series. Output voltage Adjustment range Output current 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.
