GENERAL DESCRIPTION
The most outstanding features of the DIMENSION Q-
Series DIN-rail power supplies are the extremely high
efficiencies and the compact sizes which are achieved by
a synchronous rectification and other unique 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 jumper and switches necessary. Diagnostics are
easy due to the DC-ok relay, a green DC-OK LED and the
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 application.
