Product Description
The most outstanding features of this Dimension Q- Series DIN-rail power supply are the high efficiency and the small size, which are achieved by a synchronous rectification and further novel design details. Large power reserves of 150% support the starting of heavy loads such as DC motors or capacitive loads. In many cases this allows the use of a unit from a lower wattage class which saves space and money. 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 and virtually no input inrush current make installation and usage simple with no jumpers and switches necessary. 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.
