AC Single Phase Three Stage EMC Noise Filters

Three Phase Filter Features and Benefits:

• High performance Power Noise Filter with much better common and differential mode attenuation performance and low frequency filtering effect, effectively suppress the interference from 10KHz to 30MHz. 
• FT130 series are three-stage filters comprising one common mode and two differential mode, specially suitable for very noisy applications. 
• High voltage versions above 380VAC are also available

Typical Applications of AC EMI Filters:

• Electrical and electronic equipment 
• Datacom equipment 
• Single phase servo motor 
• Inverters and converters, PLC, Variable-frequency power supply, Electric vehicle, Charging post, Various very noisy applications

1. Storage of Three Phase Filter:  

The EMI filters mustn't be left out in the heat of the sun or exposed to the rain, it should be stored in warehouse with good ventilation, surrounding temperature between -30℃ and +65℃ , the highest relative air humidity lower than 90%, and no corrosive liquid or gas.

2. Installation of Single Phase EMI Filters:  

• EMC line filters should be installed at power input, and the line inside the chassis be as short as possible to reduce radiated interference. 
• Both input and output lines of EMI filters neither be intersected nor be tied up by string.
• Make sure the mounting flange fully grounded, and keep the ground cable as short as possible if filters are connected to other equipment. 
• If the terminal is stud, please use two spanners to fasten the screw nut when connecting to avoid stud rotating and thus causing changes to the internal circuit and consequently leading to filters arcing, short circuit, broken down or the filtering effect worsened. 
• First use spanner1 to fix the screw nut near the metal case, then use spanner2 to tighten the screw nut in front( shown as Figure1), otherwise the terminals may be damaged. 
• Apply the same for the connection of other phases.
