1. GENERAL DESCRIPTION

2. 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.

Output voltage
Adjustment range
Output current

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.
