ESCRIPTION
The
most
outstanding
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.
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, the three input fuses
and 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.
