Description
The outstanding features of the 1606-XLS DIN rail
power supplies are their extremely high
efciencies and small size, which are achieved through
synchronous rectication and other technological
breakthroughs.
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, thus 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, 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.
