Emi filters

BLA ETECH

An electromagnetic disturbance which may degrade the performance of equipment also causes malfunctioning of the equipment. This process is termed as Electromagnetic interface.

Electromagnetic interface is also known as Radio frequency interface.

Electromagnetic emission is an unacceptable emission, natural or man-made, which results in the malfunctioning of the electronic or electric equipments? Major sources of EMI and RFI include microprocessors, switching power supplies, AC motors, and electrical power cords (which basically act as an antenna).

Effects of Emi Filters

•          Disturbance in the TV or Radio stations due to passing of a vehicle and an electric shaver.

•          Resets of data or loss of data

•          Burn out of sensitive components.

•          Malfunctioning of  flight controlling system due to use of laptop

•        Biological hazards

Function of EMI filters

 The basic functions of EMI filters are as follows:-

•       To suppress the high frequency interface.

•       The suppression interference equipment.

Sources of EMI filters

Emi filters have its different sources through which it can work

They are:

•          High frequency devices

•          Switching Power supplies

•          Digital circuits

•          Fans

•          Computer/ Laptop

•          Electric motors

•          Power lines

•          Electrostatic discharge

•          Microwave equipment

Different types of Emi Filters:-

·         Single phase EMI filter:- Single Phase EMI filters meet all the requirements for AC and DC power line applications.

·         Three phase EMI filter:- this EMI filter protects sensitive electronics and make them less safe, they also protect them 

·         DC EMI filter:- These filters are designed for all application standards with DC supply.

·         IEC Inlet filters: - With wide range of this kind of filter available at global designer and manufacturers of Standard and custom EMI filters.

BLA Etech is one of the leading manufacturers and suppliers of EMI filters. They provide complete arrangement in standard range of EMI filters. We try to satisfy our customers with high and best quality products. They also offer complete design and development of the EMI filters.

IEC INLET FILTER

IEC inlet filter can be defined as a practical solution to pass EMI system approval in a short time. It is also known as Power Entry Module.

Choosing this filter will help you to rapidly accepting the safety purpose of all the appliances. Power entry module combines the IEC inlet and a main filter with 2-pole switch. It gives a good performance in case of compliancesfor medical devices.

Benefits of IEC filters:-

·        Excellent performance conducted by appliances.

·        Provides good thermal behavior.

·        Tests and helps equipments

·        Switch mode power supply is present.

·        It saves the panel space.

·        Protected, per-wired and tested appliance.

·        It gives a 100% quality to other appliances.

IEC filter helps to save labor in electronic appliances and manufacturing equipments. This is basically used for non-locking appliances. Each type of couple connectors are identified by different sheet numbers.

Different types of connectors varying size and shapes are connected through different appliances.

Detachable appliances are used for office equipments, manufacturing factors etc.

IEC standard vary differently as every standard is used for different purposes like office or general purpose. They are also available in low current medical versions and also for the general purpose.

They are mainly required for equipments like computers, TV, toys, switches etc and also for fitness equipments.

Since Power entry Module is connected to the AC power line, they are meant to safety standards.

Power entry modules are quickly connected to any other equipment. It helps to reduce the cost and labor effectively.

They are specially benefited for medical equipments and appliances. They are available with electromagnetic interface that allows connections to the equipments.

They are also available at water resistant. Power entry modules take full responsibility of making power entry module products.

The direct current powered modules are specially used for telephone exchange modules. They are made with the seal opening protection at the panel opening, around the fuse holder.

Inlet manufacturers have expanded on the flexibility of production of IEC filter that are used by labor in manufacturing process and many other process.

It is not possible to connect all the equipments with one power module. Equipment designers are responsible for the safety purpose of the modules. As fuse and fuse holder combinations, the thermal compatibility has to be considered properly.
