PRODUCT DESCRIPTION
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.
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.
