ENERAL

ESCRIPTION

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.

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.
