Output Chockes


Output Chokes
The Output Chokes can be used in combination with line filters to diminish the electromagnetic interference.

They are specially effective when the interferences radiated by the connection driver to the motor, cause disturbances in the control systems, data lines or radio and television receivers located near the installation. The setting up of the appropriate choke in the connection cable to the motor, can solve this kind of problems.

Occasionally, the problems of electromagnetic compatibility can appear in an installation when the components that are part of the same control group affect each other; for example, the open control panels can produce interference on the low amplitude signal circuits of sensors. In these cases the inclusion of a toroidal inductance in the cables of the control circuit and sensors, usually solves the problem. Normally, to determine the number and situation of the additional chokes is necessary to make some tests until getting the best configuration.

Sinus filters

SF series
Sinus Filters

The frequency inverters for the speed control of the AC motor, nowadays, in all industrial areas are to be find and in different applications such as bombs, air conditioning systems, scheme tool and in industrial automation in general.

The frequency inverters uses technical as PWM, output voltage quick pulses, etc… These techniques have some disadvantages like motor oneheat, high levels of electromagnetic interference and the necessity of expensive shielded cables.

The senoidal output filters for frequency inverters are designed in order to provide a complete solution to all these problems.
