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 application, 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.

A new standard across
a whole product range
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.

LTE technology
takes the heat off
our power chip
In conventional power relays, excessive heat generated
by the power chip can lead to metal fatigue due to the
different thermal expansion rates between the chip,
the heat conductor and the current clip. In addition,
air pockets in the soldering create hot spots on the
chip, which can also impair performance and cause
breakdowns. LTE technology solves the problem in
a unique way to give you a high quality product
with extremely long life:
•
New materials virtually eliminate the effects
of thermal expansion in the power chip
•
New design with fewer soldering points increases
heat dissipation
•
New one-shot vacuum soldering process prevents
the formation of air pockets and hot spots
And they’re as easy to
specify and install as
ordinary contactors
The CI-tronics power chip consists of a silicon
device soldered in a sandwich construction
between a current clip and a heat conductor
assembly. The chip allows current to flow when
a control voltage is applied to the gate.

Contactors and motor controllers play a relatively small if
crucial role in most processes, so why should choosing the
right component be so complicated. You’ll find CI-tronic
components refreshingly easy to work with — as simple to
specify and install as standard electro-mechanical devices
and vastly easier to deal with than conventional SSRs.
It only takes a moment to configure them, and there’s no
need for heat sinks or varistors. CI-tronic components can
be dimensioned to their full rated power and are delivered
as a completely engineered product featuring:

CI-tronicTM means fewer
burnouts, better process
control, longer heater life
It can happen to any OEM. You deliver a large
and expensive system to a customer far from home.
One day there’s a breakdown and an urgent call for
help. A service rep is dispatched to solve the problem
only to find a burned out contactor in the heater system — a small fault but one that ends up costing
you time, money, maybe even a little goodwill.
Whether you’re producing equipment for injection molding, die casting, shrink wrapping or baking,
constant operation eventually takes its toll on your
heat control switch. Naturally, you can help avoid
the unexpected by choosing contactors that are reliable. But you can also make contactor replacement
an even rarer occurrence by equipping your system
with CI-tronicTM components.
CI-tronic contactors are purpose-built for
demanding industrial applications — or applications
where you just don’t want to risk that unexpected call
in the night. With LTE technology, burnouts due to
thermal stress become a very remote concern. CI-tronic
contactors outlast solid state relays by a factor of 10
and outperform electro-mechanical contactors by an
even wider margin. And they’re price competitive, too.
CI-tronic products also gives you better control
of your heating process and longer heater life.
Control is improved by the use of faster switching
patterns which provide more stable process temperatures, which in turn reduces thermal stress and
extends heater life.

The versatile ACI analogue power controller is designed for very precise temperature and transformer control.
Due to the built-in micro-computer the controller can operate in phase angle as well as in burst firing control method.
The controller automatically adapts to the load to ensure a smooth inrush, and in burst-firing mode it will further
eliminate the unwanted effects of DC magnetizing on transformers. The ACI unit is easily connected to a
PLC/regulator by means of one of the selectable input signals.
Analogue control of heaters and infrared lamps. The ACI controller is also ideal on transformer controlled processes.

CI-tronicTM also represents
an affordable breakthrough
in motor controls
Motor controllers
CI-tronic motor controllers
can be adjusted precisely for
the needs of your application.
Ramp-up and ramp-down
times can be set from 0.5 -10
seconds. Starting torque can
be adjusted from 0-85% of
nominal torque. And for applications with high breakaway
torque the controller can
provide a kickstart of full
torque for 200 ms.

Soft starters are a tested way to keep torque surges
in AC motors from damaging the equipment they’re
meant to control — nothing new about that. What
is new, however, is that now there’s an affordable
line of these controls designed specifically for smaller
motors — the CI-tronic range from Danfoss.
CI-tronic motor controllers cover the power range
from 0.1 to 15 kW. They’re ideal for applications
that require smooth starting and stopping but that
don’t call for the expense of a conventional soft
starter. Use them on pumps, fans, conveyors, gear or
belt-driven machinery and countless other types of
equipment. They provide precise control while reducing the shocks and vibrations that are a major cause
of equipment failure and downtime. In addition, by
reducing inrush currents during motor startup they
eliminate power dropouts that can damage sensitive
electronic equipment, saving you the expense of having
to reinforce the line.
There are also a variety of CI-tronic controllers
for more specialized tasks. For example, our motor
contactors and reversing contactors are ideal for
applications with frequent starts and stops. A zero
cross-switching technique is used (the contactor always
switches when the voltage is zero) to ensure speed
and accuracy. These reliable products provide long
service on everything from automatic doors to thread
cutting machines and are an effective way to control
difficult functions like “inching” on cranes.
Finally, for less demanding applications it’s hard
to beat our starting torque limiters, which offer the
dependability of CI-tronic technology at highly
attractive prices.
Everyone benefits
Regardless of the application, CI-tronic motor controllers
provide smooth and precise starting and stopping while
reducing wear and tear on your equipment. But they also
benefit individual applications in specific ways.

The digital controlled MCI soft starter are designed for smooth control of 3 phase AC motors.
The MCI controller has individually adjustable acceleration and deceleration times. Thanks to the adjustable initial torque
and the unique breakaway (kick start) function the controller can be optimized for almost any application
AC motor application where a smooth start and/or stop is advantageous, such as conveyors, fans, pumps, compressors and high
inertia loads. MCI controllers are also obvious as replacement of star/delta starters

MCI 25B motor controller with brake is designed for soft starting and braking of 3 phase AC motors. The digital controlled soft
starter features accurate settings and several monitoring functions. Acceleration time and initial torque are along with the braking
torque easily adjusted.
During braking the MCI 25B will apply a DC current to all the windings of the motor, thus providing a powerful brake function.
The automatic stop detection ensures a safe operation. For positioning applications the unique slow speed function can be applied.
The MCI 25B controller is typically applied on demanding braking applications such as saws, cranes, grinding machines,
automatic doors, etc.

Wiring of overload
protection
Optional thermal overload protection is possible by inserting a thermostat in the slot on
the right-hand side of the controller.
The thermostat is connected in series with the
control circuit of the main contactor. When the
temperature of the heat sink exceeds 100 °C the
main contactor will be switched OFF. A manual
reset is necessary to restart this circuit.
