Puls DIMENSION Q Series Manual

Q-Series
P D
RODUCT ESCRIPTION
The most outstanding features of the DIMENSION Q- Series DIN
rail power supplies are the extremely high efficiencies and the
small sizes, which are achieved by a synchronous rectification
and other technological designs.
The QS40.484 is a device for 200-240V mains voltages. 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 input fuses as well as
the near zero input inrush current make installation and usage
simple. Diagnostics are easy due to the DC-OK relay, a green DC-
OK LED and the red overload LED.
A large international approval package for a variety of
applications makes this unit suitable for nearly every
application.
