GENERAL DESCRIPTION
The most outstanding features of this Dimension
QS40.241 DIN-rail power supply are the extremely high
efficiency and the small size, which are achieved by a
synchronous rectification, a bridgeless PFC circuit and
additional unique design details.
Large power reserves of 150% and built-in large sized
output capacitors 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 emissions makes usage in nearly
every environment possible.
The integrated input fuse 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.
