CI-tronic TM

CI-tronic ^TM 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 thank to their unique design outlast conventional SSRs by a factor of ten.

The secret ? At the heart of every CI-tronic component is a new power chip that eliminates the thermal problems wich 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 applications, while CI-tronic motor controllers can be used on everything from conveyors to cranes.

Just as important, like all Danfoss controlls CI-tronic components come with our usual assurance of globat 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 operationg 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 pochets in the soldering create hot spotes on the chip, which can also impair performance and cause breakdowns. LTE technology solves the problem i a unique way to give yo a high quality product with extremely long life:

• New materials virtualy eliminates the effects of thermal expansion in the power chip

• New design with fewer soldering points increasis heat dissipation

• New one-shot vacuum soldering process prevents the formation of air pochets and hot spots

And they're as easy to specify and install as ordinary contactors

Contactors and motor controllers play a relatively small if crucial role in most processes, so why should choosong 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:

• Compact modular construction

• DIN-rail mountable design

• Industry standard rating

• Universal control voltages

• LED status indicators

• Logical control settings

CI-tronic means fewer burnouts, better process control, longer hater 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-tronic components.

CI-tronic contactors are purpose-build 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 ourperform electro-mechanical contactors by an even wider margin. And they're price competitive, too.

CI-tronic products also give 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.
