CI-tronic
stands
for high performance
and long life
There are many ways to control a heating process or a
motor, but you’ll have a hard time finding a better way
than with Danfoss CI-tronic components.
The CI-tronic concept represents a breakthrough in
contactor technology. In effect, we’ve revolutionized the
solid state relay to create a range of electronic contactors
and motor controllers that are as simple to use as they are
advanced. On the one hand, CI-tronic contactors are as
easy to specify and install as ordinary electro-mechanical
components. On the other, they provide the switching speed
of a solid state relay, yet thanks to their unique design
outlast conventional SSRs by a factor of 10.
The secret? At the heart of every CI-tronic component
is a new power chip that eliminates the thermal problems
which cause early burnouts in traditional SSRs. We call the
technology “LTE,” for low thermal expansion, but bottom
line for you is significantly greater reliability
and operational life.
Danfoss CI-tronic contactors are ideal for
just about any type of industrial heating appli-
cation, while CI-tronic motor controllers can
be used on everything from conveyors to cranes.
Just as important, like all Danfoss
controls, CI-tronic components come with
our usual assurance of global availability,
fair prices, volume supply and fast delivery.
And, of course, responsive service, if needed.
CI-tronic components set high standards for quality
and reliability, but you’ll also be impressed by the
sheer scope of the product range. It includes both
electronic contactors and analog power controllers
as well as soft starters, torque limiters, reversing
contactors and other types of motor controllers.
Moreover, CI-tronic contactors already comply with
IEC/EN 60947-4-3, the coming EU standard that
will put tight new controls on ambient and operating
temperatures and EMC immunity and emission.
