PULS QT20.241 INTRODUCTION
The most outstanding features of the DIMENSION QSeries DIN-rail power supplies are the extremely high
efficiencies and the compact sizes, which are achieved by synchronous rectification and other unique design
details.
Large power reserves of 150% support starting heavy loads such as DC motors or capacitive loads. In
many cases, this allows using a unit from a lower wattage class, saving 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 DC-OK relay, a green DC-OK LED, and the
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 application.
